How to fix Icom IC-Q7E frequency when it cannot be set?
If you cannot set the frequency on your Icom Transceiver, the lock function may be activated. Push [FUNC] + [(CALL)LOCK] to cancel the function. Alternatively, channel indication mode may be selected; turn the channel indication mode OFF in set mode.
How to fix Icom IC-Q7E Transceiver when no power comes on?
If your Icom Transceiver does not power on, the batteries may be exhausted. Replace them. Also, verify that the battery polarity is correct.
Why is transmitting impossible on my Icom IC-Q7E Transceiver?
If transmitting is impossible on your Icom Transceiver, the batteries may be exhausted. Replace the batteries. Also, check if a frequency outside of the 144/400 MHz amateur band is set; if so, reset the frequency inside the 144/400 MHz amateur band.
What to do if no sound comes from the Icom IC-Q7E Transceiver speaker?
If no sound is coming from the speaker of your Icom Transceiver, first check that the volume level is not too low by pushing [VOLY] to a suitable level. Also, if using tone squelch, a different tone may be selected. Check the tone using tone scan.
What to do if desired set mode item cannot be selected on Icom IC-Q7E Transceiver?
If the desired set mode item cannot be selected on your Icom Transceiver, it may be in expanded set mode. Turn the expanded set mode ON. Also, some set mode items can be selected from VFO or memory mode only. Enter set mode from the appropriate operating mode.
Why does my Icom IC-Q7E Transceiver make no beeps?
If no beeps sound on your Icom Transceiver, the beep tones may be turned OFF. Turn beep tones ON in set mode.
What to do if dial select step cannot be used on Icom Transceiver?
If the dial select step cannot be used on your Icom Transceiver, the RIT function may be activated. Push [FUNC] + [BAND] to cancel the function.
