Why doesn't the memory scan start on my Icom Receiver?
If the memory scan on your Icom Receiver doesn't start, it's possible that fewer than two memory channels have been programmed. Program two or more memory channels to resolve this.
Why is the select memory scan not starting on my Icom IC-R75 Receiver?
If the select memory scan isn't starting on your Icom Receiver, it could be because fewer than two memory channels have been designated as select channels. Designate two or more memory channels as select channels for the scan.
