Q
When I read/write frequency, the computer prompts "Initialization serial port error, communication failure".
A
The reasons might be:
1. The PC software model and version are incorrect;
2. The radio is not powered on;
3. The program cable is not original from the manufacturers;
4. The USB interface driver is not installed;
5. The wrong port is chosen;
If not the reasons above, please contact the manufacturer and distributor.
Q
How can I cancel my password if I forget my read/write password?
A
The radio has no defaut password. The password is manually set. If you need to remove the password, you need to return the radio to the factory or contact the local dealer.
Q
How to deal with water ingress?
A
Remove the battery; disassemble the radio including the antenna, frame, circuit board, conductive rubber, etc.; clean it with absolute alcohol and leave it to dry.
Q
Will it damage the battery to continue charging after the indicator turns green?
A
No, it will not. Lithium battery voltage is less than 8.4 v. Charging termination voltage is decided by the lithium battery charger and the radio's protection board. It is the main means of voltage detection. When the charge voltage reaches the valve value, the circuit inside the charger or lithium battery protection board switch tube will be shut down immediately. Then the charging indicator turns green and continuing to charge will not damage the battery.
