If there is no display on your Kirisun Portable Radio after switching it on, the battery power may be insufficient; try to recharge or replace the battery pack. If this does not work, the power switch may be broken and need replacement. In some cases, the CPU or regulator tube Q45 may be broken, requiring IC replacement.
Why Kirisun Two-Way Radio cannot transmit?
If your Kirisun Two-Way Radio is unable to transmit, it might be because the frequencies of both users are not the same. To resolve this, select the same frequency channel again.
How to fix phase locked loop unlocked with “tick, tick” sound in Kirisun Two-Way Radio?
If you hear a “tick, tick” sound and the phase locked loop is unlocked on your Kirisun Two-Way Radio, the issue could be: * A broken Phase locked loop Crystal Oscillator X1: Replace it. * A broken oscillator tube: Replace it. * A broken Phase locked loop IC2: Replace the IC.
What to do if my Kirisun Portable Radio has no display after being switched on?
If your Kirisun Portable Radio's display doesn't turn on after you switch it on, the issue could be due to several reasons: * The battery power may be insufficient, so recharge or replace the battery pack. * The power switch may be broken, consider replacing it. * The CPU may be broken, consider replacing the IC. * The regulator tube Q45 may be broken, consider replacing the IC.
Why can't my Kirisun Portable Radio transmit?
Your Kirisun Portable Radio might not be able to transmit due to a few reasons: * The frequencies of both users are not the same. To resolve this, select the same frequency channel again. * The CTCSS/DCS signaling of both users are not the same. To fix this, set it with PC. * You might be beyond the efficient communication range.
What to do if my Kirisun Portable Radio transmitting red light is on, but no voice is heard?
If the transmitting red light is on but no voice is heard on your Kirisun Portable Radio, consider the following: * The power-amplifier tube may have no power output, so replace the tube. * The microphone might be broken. * The operational amplifier IC14 may be broken, so replace it.
What to do if my Kirisun Transceiver has no signal?
If your Kirisun Transceiver shows no signal, several factors could be at play. First, ensure the antenna is securely connected. Other potential issues include low sensibility (requiring trimming in computer test mode), a broken HF amplifier (requiring replacement), a squelch level that's too high (needing a reset via PC), a broken Mixer tube Q19 (requiring replacement), or a broken Frequency Modulation IC4 (requiring replacement).
What to do if receiving green light is on, but no voice is heard on Kirisun Portable Radio?
If the receiving green light is on but you hear no voice on your Kirisun Portable Radio, the speaker may be broken and needs replacing. Other potential issues include a broken audio power amplifier IC9, a broken switch tube Q48, or a broken operational amplifier IC6; in each case, replace the corresponding component.
What to do if Kirisun Portable Radio has no signal?
If your Kirisun Portable Radio shows no signal, ensure the antenna is well connected. Low sensibility can also cause this issue, try trimming in 'computer test mode'. Other potential causes include a broken HF amplifier (replace it), a squelch level that is too high (reset it by PC), a broken Mixer tube Q19 (replace the tube), or a broken Frequency Modulation IC4 (replace the IC).
What causes abnormal programming in Kirisun Portable Radio?
If you are experiencing abnormal programming with your Kirisun Portable Radio, consider the following: * Make sure the wires are well connected. * There may be abnormal output of the RS-232 serial port of the computer, so check the computer. * There may be an abnormal connection of MIC and SPK jack, so check the jack.
