Ericsson T39 evaluation

Test methods and precautions for second-hand licensed and European stocks (t39m) and brand-new lines (t39mc) are as follows.

1. In terms of appearance, t39m and t39mc have nothing to say, whether they are close to brand-new or brand-new. There is nothing to say, just look at how flexible the flip cover is, and pay attention to whether the metal shell of the front shell and the antenna bottom and tail of the rear shell are worn. As for the protective stickers on the screen, the previous post has a detailed description, so I won't say it. Whether the antenna is original. There should be a fragile sticker on T39mc antenna to see if it is damaged. As for the second-hand cable, look at the wear degree of the antenna and tail of the front shell and the back shell, as well as the wear of the keyboard. Overall, give an evaluation, whether you can accept it. Second-hand people should pay special attention to the flexibility of flip cover. In addition, you should also test the side keys. When standby, press the side key up and down, and the standby time will be displayed. There is also a keyboard light, and the flip test is opened in a slightly dark place. As for the label of the back shell, t39m is almost irregular. At least three tips from Ericsson are wrong. There are detailed pictures in my friend's photo album. Please pay attention. Of course, if you encounter regular water, it may also be positive water.

2. Function test: Make a phone call first and see how the receiver and microphone are. If you feel that the other party's voice is low, you can push the side key up, and the screen shows the size of the receiver, up to 8. Enter the process mode, press the right * Zuo Zuo * left * key in standby mode, 1. 1 is the software version, and the latest r4a008, 1.2 is the lock of the sim card; 1.3 is imei. Note whether this is consistent with the label on the back shell. 1.3 is a function test. Test it separately to see if there are any problems. 1.3. 1 See if there are any bright spots or black spots on the screen; 1.3.2 See whether the signal light and screen light work normally; 1.3.3 is the keyboard. Press all keys in turn to test whether each key is good. 1.3.4. Buzzer; 1.3.5 vibration 1.3.6 receiver; 1.3.7 microphone. If you don't want to make a phone call to test your mobile phone, you can use 1.3.6 and 1.3.7 to test the listening microphone. 1.3.7 Just rub the microphone with your hand to see if you can hear it, and test the sound source line and transmitter at the same time. 1.3.9 Needless to say, the number of flip covers is a concern. The second-hand flip cover 20000 has basically been used for at least one year. The flip cover can be reset, so don't worry so much.

3. Others: signal, whether the main version leaks electricity, Bluetooth, infrared. And whether the mobile phone password has been changed, the default is 0000. In addition, if you can open it yourself, you can look at the usage of the keyboard pad.

1. See if the seal has been torn off: it's white with Ericsson's logo.

Note: Some merchants open the box for inspection in advance, with anti-counterfeiting labels. It doesn't matter whether this machine has been used or not. We have the following test methods.

Look at the color: Do you need the color of your mobile phone?

3. Appearance inspection:

After closing, flip the lid to check whether the seam is even and symmetrical.

Antenna: Turn it gently by hand to see if it is loose. About 60% of the antennas are loose.

The appearance of aluminum alloy front mask, whether there are scratches and looseness (just press it obliquely).

... press the connector around the phone (especially the bottom of the phone), is there a big gap? ...

4. Whether there are opening marks at the groove, anti-counterfeiting label and anti-image screw where the battery is installed.

5. Record the serial number and production date of IEMI on the label. Insert the SIM card.

Check the battery: Ericsson's anti-counterfeiting laser logo is on the model label of the battery. The battery has been charged to golden yellow, and there is no trace on the surface (if used, there are traces). On the back is a trademark, which is composed of letters and three letters of Ericsson to distinguish it from previous batteries. In the middle of the trademark, there is a smooth surface (mirror sense). If you look carefully, there are no scratches caused by light. Battery model bus-165438. 3.6V600mAH。

Once the battery is installed, it should be flush with the back of the phone. Press gently, leaving no gaps.

⒏ Press the NO key to turn on the computer, and there will be three prompts after finding the network.

? Press 1 time for each key, and check the contact sensitivity of the key.

⒑ Click and click 1 time to test the effect. Slide the volume button on the side to detect the sound during the call.

... class =' class1' > note: when typing, check whether there is a black spot (screen) above the name on the screen. )

Send text messages to check the effect of stroke input and text messages.

5] check the serial number IEMI three places must be the same:

First place: inside the machine, press *#06# to display letters.

.......... (or press > *< *< *, and select item 1 in the service information, item 3).

Second place: See item 5 above. Printed on the label on the back of the fuselage;

The third place: the outside of the box, on the white label ...

⒔ Check the turnover number: after pressing > * < lt * < *, select the turnover counter in item 9 of the third maintenance test.

Note: Generally, flipping the cover within 20 times means that no one has used it. ...

5. record version number: press > *< *< *, select item 1, and service information. Select the project 1 and press Yes to get the software information.

5] Turn off the power repeatedly and turn it on again. Check whether it is sensitive.

[6] Issue a formal invoice (it is recommended to buy it at Aiji Store), and the invoice must indicate: a. The serial number of the mobile phone and the purchase date of IEMI.

1. Be sure to look at the number of flips when buying. Press > * < < * < *, and then press the number keys 3 and 9 to check the number of flips. Indicates that someone has tried or used it more than 10 times. /kloc-no one took it for 0/0 times. Generally, the new machine is 3-5 times. Press the number keys 1 and 1 again to view the software version.

3. Depending on the appearance of the machine, check whether each key feels good, dull, astringent and inflexible. Press once to see if the rear shell and the front shell are in close contact, and then press the surface metal plate and charging input terminal diagonally to see if the metal plate is loose.

3. Slide the volume adjustment button on the left to check the standby time. If the new machine is over 70 hours, it is better to let MM charge for 30 minutes. It is better if the standby time exceeds 100.

4. Twist the antenna by hand to see if it is loose, and press the battery left and right to see if it is loose or in poor contact.

Make a phone call, listen to the call quality, and press the volume button on the left to see how it changes. In the meantime, let the other party feel whether the sound quality of the call is clear, and see if there are three black spots or screen phenomena on the screen. Send another text message and receive another text message to see if it is normal. Call 1 12 again to see if the background noise is very loud.

It is annoying to see many people on the forum saying that the phone number of 39 is not easy to find, including many elderly people, saying what letters should be added in front of the stored phone number? I don't know if I didn't hear you clearly or what. Let's talk about how I found the phone number smoothly and quickly: press the right button of 39 and the words "find and dial" will appear. If the settings are correct, we only need to enter the name of the person we are looking for here, and we can quickly find the phone number of that person.

Let's see how to set it in the address book; Select 1 (Address Book) -2 (Add Contact)-In the column of "Name", we directly enter the contact name "XXX" to be saved, edit the number and exit, and then select 8 (option) under 1 (Address Book)-and then select 6 (sort order)-select to arrange by "name".

Similarly, if we put the contact's name "XXX" in the column of "Last Name" in the above steps, then after quitting editing, we will follow the same steps to 8 (Options)-6 (Sorting Order)-Select to arrange by "Last Name".

After setting the number according to the above steps, can you find the phone number conveniently?

When the monthly view of the shortcut is placed in the first place, press the left arrow key of standby time to immediately bring up the day of the week.

Second-hand T39mc is now on the market, and there are many refurbished machines and assembly machines. The following is my own experience for the reference of airplane friends.

First of all, the following explanation should be clear: T39mc in any of the following situations is not recommended to be considered, so as not to worry about buying an unsatisfactory T39mc.

1. The IMEI of the fuselage is inconsistent with the IMEI on the back of the machine (unless the seller shows the maintenance instructions for replacing the motherboard in customer service). Most of the IMEI inconsistencies are assemblers, even the refurbished machines whose motherboards have been eliminated from the production line-assemblers, whose performance is unstable. )

The color of the antenna is not light gray. The material is too smooth. An antenna is like a human eye to 39. Poor eyesight (antenna is not original). The consequences can be imagined. The assembly signal is poor and the material is smooth. )

3. The data on the energy dashboard, pressing the side key to display the standby time and call time, is obviously not in line with the actual situation. There is something wrong with the battery chip. It is difficult to ensure that Bluetooth, infrared and others are intact. )

4. The keyboard is not silver. (The original keyboard is silver, and all three colors and 39 have been seen. The original keyboard has excellent wear resistance and color transparency. )

The antenna on the back of the old machine is not worn. (magnesium-aluminum alloy back shell is easy to wear. If not, it is usually painted or renovated. )

6. The gap between the back cover and the front cover of the machine is relatively large. (After the shell is opened, the gap will be larger. After the repair, 39. I didn't investigate any specific problems. )

7.8 of ⒎IMEI is not 63 (Nanjing). 7 1 (Malay). 5 1 (Sweden). (39 sources outside these places are a bit hanging, which may be the aforementioned elimination of motherboard assemblers. )

⒏ During the call, a small triangle (with an exclamation mark in the middle) symbol will appear on the screen, indicating that the call is not encrypted. I don't recommend personal opinions on issues worth discussing. )

(9) Smell the pine fragrance in the battery cell. (Rosin is needed for spot welding when repairing the motherboard. )

⒑ Enter the factory setting, and the password is not 0000. (This will lead to unsuccessful factory settings in the future, and the problem is not light. )

⒒ engineering mode > *< < lt *< *, the screen is broken.

(5) There is a sizzling current sound on the receiver during the call (both the receiver and the motherboard have problems).

⒔ Ericsson's logo, the three bars are not horizontal twill (vertical twill). (Ericsson's trademark, if there is a whiteboard inside, it must be an assembled shell, even the shell is assembled, and the inside can be imagined. )

Tips for use and entry of engineering mode

The use of telephone books.

The quickest way is to put the English letters of the name in front of the phone book.

For example, Wang Xiaoxiao can be edited by W Wang Xiaoxiao in the phone book. So you can enter quickly by pressing the 9 key.

For example, baby can edit baby B.

In addition, after 2000, all models support the group function, so it is very important to manage your family, classmates and so on, because you can send short messages in groups.

Most of Ericsson's mobile phones support fast name search for card slots.

For example, I write the top ten of my cards as my most frequently used and closest people. I can quickly enter the first few digits of my calling card by calling, and I can write the location of people I often use as 1, 6, 8 and so on, which you think is easy to remember.

Then stand by, enter 1#, 6#, 8# to quickly find the desired mobile phone, and so on.

The use of short messages.

It should be noted that because Ericsson's mobile phone software integrates too many functions, it is necessary to delete useless messages as much as possible, otherwise the speed of mobile phone software will slow down.

In addition, the * key and the # key can switch the input method and punctuation. If you don't have the input method you want, don't worry. See if your input method is not adjusted at all. You can find it by setting the second item in the sixth language setting in your mobile phone. Press the * key to select the desired input method, or you can clear the input method that is not commonly used.

3. Numbers enter the menu. Ericsson's later machines all support digital entry menu. Once you are familiar with it, you can quickly enter the menu. For example, 39, after pressing the left and right keys to enter the menu, press the number 3-3-8 to directly enter the SMS counter menu. Press 4-5-3-2 to adjust the standby screen. This can be entered quickly.

2. SMS counter and call counter are very useful, and you can control and understand your SMS and call volume every month. I usually reset it at the end of each month, so that I can know how many calls I made and how many text messages I sent.

5. Enter the engineering mode. In standby mode, enter right * Zuo Zuo * left * to see if the network lock is left * * left.

The side keys of a mobile phone are also up and down keys.

You can check the date and other status of the mobile phone, enter the menu or use the side keys to operate up and down. During the call, the side key is still a tool to adjust the volume. If the incoming call cannot be turned over and refused, you can press the up key twice.

Disadvantages of T39

T39, a classic of Ericsson. However, it also has the following disadvantages (take r2k version as an example):

1. When the flip cover is closed, press the no key to turn it on and not turn it off. If the yes key cannot bring up the call list, press the yes key again to make a call.

3. When searching for dialing in the phone book, you can't directly press the yes key to enter the name list. You must select a word in the input method state and press the no key, then press the yes key to enter (this is not as good as T68);

3. When the battery is low, the prompt menu appears for too long, during which the mobile phone does not respond to the key operation. If you make a phone call at this time, the prompt of low battery appears for a long time, which makes the calling number not displayed for a long time, which is very inconvenient;

3. It is unnecessary to press and hold the C key to change the mute option (this is not as good as t 18).

Of course, this can't change the heroic qualities of t39 classic. If the Ericsson brand does not fall, there will be a better t39 improved model.
