If the above examination is no problem, then there may be a part of the interphone itself has failed, including:

Speaker

2. Speaker external socket;

3. Encoder and potentiometer;

4. Soft circuit plug and motherboard socket contact situation;

5. Antenna and the antenna contact with the situation;

If it is the problem of the above components, you need to special repair radios or small appliances to the place to be replaced.

Second, the radio launch issue

Launch key is the most frequently used radio components, a lot of repaired Walkie Talkies are due to the launch button out of the question and affect the normal use. In addition, if there is a problem radiating radio, first check the battery is energized, the battery is no problem, then there may be several reasons:

1. launch button (PTT key) the outer rubber aging or damage;

2. External microphone socket shrapnel poor contact;
