What to do if Kirisun PT8000 Radio LED lights green but no voice is heard?
If the LED on your Kirisun Radio lights green while receiving, but you hear no voice, the issue likely lies with either the speaker or the audio power amplifier. The speaker may be broken, and require replacement. Alternatively, the audio power amplifier IC7 may be broken, also requiring replacement.
Why does my Kirisun Radio beep with PLL unlocked?
If your Kirisun Radio is beeping and showing a PLL unlocked error, it could be due to several reasons. First, the channel frequency might be beyond the limit; reset the channel data. Second, the PLL crystal oscillator X1 may be broken, requiring replacement. Third, the oscillator transistor might be broken, also requiring replacement. Finally, the PLL IC3 could be broken, necessitating its replacement.
What to do if my Kirisun Transceiver fails to power on?
If your Kirisun Transceiver fails to power on, consider the following: * Ensure the power cable is securely connected to both the accumulator and the host. * Check the power cable's protective tube for burnout and replace if necessary. * Inspect the power button for poor contact; replace the silica gel button or PCB button if needed. * Verify the rechargeable battery has power; recharge or replace it if depleted. * If none of the above steps work, the CPU might be broken, consider replacing the IC.
Why does my Kirisun Transceiver have no talkback?
If your Kirisun Transceiver has no talkback, it might be due to several reasons: * The selected frequency might be incorrect. Try reselecting the channel with the correct frequency. * The CTCSS/DCS code might not match. Reset the CTCSS/DCS code to ensure it is the same as the receiving unit. * You might be out of the effective communication range.
How to fix a Kirisun Transceiver beeping due to phase lock loop unlocked?
If your Kirisun Transceiver is beeping because the phase lock loop is unlocked, try the following: * If the channel frequency is beyond the specified range, reset the channel data. * If the crystal X1 of the phase lock loop is broken, replace it. * If the oscillator tube is broken, replace it. * If the IC3 of the phase lock loop is broken, replace the IC.
Why does the red transmission indicator light up on my Kirisun Transceiver, but no sound is heard?
If the red transmission indicator lights up but no sound is heard on your Kirisun Transceiver, it could be due to: * A damaged Power module IC1 with no power output, please replace the module. * A damaged MIC, please replace it.
