1. There are three main switches or knobs used in the walkie-talkie. The knob on the left side of the top is the switch, and the volume can also be adjusted. The knob on the right side of the top is responsible for adjusting the corresponding channel.
2. When turning on, turn the switch knob clockwise, there is an obvious startup sound and the indicator light will flash green once, then adjust to the appropriate volume.
3. Then adjust the walkie-talkie to the same channel, if there is frequent noise, it may conflict with other people's walkie-talkie channel, you can switch other channels to avoid interference.
4. When receiving communication from others, the indicator light will flash green.
5. When you need to speak, press and hold the voice key and start communication. Release the voice key in time after the voice is finished.
6. If the charger is used for charging, the charger indicator light is red and does not blink, it is normal charging, and it turns green, indicating that the charging is complete. If the indicator is blinking, it is likely that the intercom is not in good contact with the charger, and it needs to be reinserted for charging.
Walkie-talkie red light has been on the solution, you have to provide the specific model of the machine, such as TK-208 or TK-308, these two machines are nickel-metal hydride batteries, batteries do not have a similar protection board of lithium batteries, inserted in the charger is always charging, often touch, the battery is hot and quickly pull it off, otherwise it will be very damaged!
1. Do not fold the antenna.
2, do not transform or adjust the walkie-talkie. Wireless walkie-talkies should be used correctly to reduce human damage. If any damage is found, the supplier shall be notified in time to repair the damaged wireless radio equipment in time
3, do not put the walkie-talkie next to the heating appliance.
4. If you press the PTT key to speak, the indicator light of the machine flashes red and emits a warning tone, indicating that the battery is used up; The battery needs to be replaced immediately.
First check whether the quiet ratio coefficient of the walkie-talkie is set to 0 or there is signal source interference around. After discharge, the phase detector on the back of the circuit board is also called the demodulator, according to his corresponding specifications of 400 megabits or 450 megabits, it can be replaced, and sometimes because of the knock of the walkie talkie, a contact Angle of the demodulator is broken, which will also produce such failures. Or the surrounding capacitors could break or deteriorate.
That is insufficient power, charge the power on the line, nothing big, this is the reason for the lack of power, if this happens, must first charge, it is not a big thing, sometimes there will be insufficient phenomenon, this is a normal phenomenon, there is a situation that the battery is not working, this situation will have to change the battery, basically will not appear now
