Why can't I hear the speech after pushing SPEECH on my Icom Transceiver?
If you cannot hear the speech after pushing SPEECH on your Icom Transceiver, the speech level may be too low. Adjust “SPEECH Level” in the Speech setting.
Why doesn't the programmed scan start on my Icom Transceiver?
If the programmed scan does not start on your Icom Transceiver, it may be because the same frequencies have been set in scan edge memory channels P1 and P2. Set different frequencies in scan edge memory channels P1 and P2.
Why won't the memory scan start on my Icom Transceiver?
If the memory scan does not start on your Icom Transceiver, it is possible that no, or only 1 memory channel is set. Set at least 2 memory channels.
Why doesn't the select memory scan start on my Icom Transceiver?
If the select memory scan does not start on your Icom Transceiver, it could be that no, or only 1 memory channel is designated as a Select channel. Designate at least 2 memory channels as Select channels for the scan.
How to save changes to a memory channel on Icom Transceiver?
If the contents of a selected memory channel is not changed on your Icom Transceiver, and you want to save the changed settings, touch [MW] for 1 second to write them into the memory channel on the VFO/MEMORY screen.
