Check that menu item 43 (SCN MD) is set to 'MEM'. If it's set to 'ONLY' and if any of your memory channels are configured as 'ONLY' (flashing '>' top left of display) then only those will be scanned. Setting SCN MD to 'MEM' will allow you to scan all channels that have not been set to 'SKIP'. A channel set to 'SKIP' will be identified with '>' in the top left of the display.
