How to change the word of the police car led flash sign?

Methods of replacing characters on led billboards;

1. Connect the LED display screen to the computer by changing words, open the display screen control software, set the screen parameters, edit the program font, and click Send.

2. Change the words through the USB flash drive. If you use a USB flash drive control card, there will be a column in the software menu. Click USB download and save the setting parameters and contents to the USB flash drive. When changing the program, you only need to copy the content with a USB flash drive and bring it to the LED advertising screen for replacement.

3. Change words by mobile phone (or remote control) If you use the GSM mobile phone SMS control card in the LED display, then the mobile phone is the one you use to change words. First, you need to edit SMS to send and change advertising subtitles. Usually, it is recommended to use USB or GPRS, which is convenient and saves time. In addition, it is necessary to combine the actual needs, such as shops and stores, to send directly through wired control cards and computers, or choose to use U disk control cards. If you want to change the advertising content, you can copy directly with U disk. If the number of LED advertising screens is large and scattered, and you want to send them in groups, then you advocate using GPRS wireless control card to correct the contents in computer software, and then send them in groups with one click, which is labor-saving and convenient.
