My Fm4 has a strange problem, I have replaced the back up battery and this
is working, if I store a station at 88.10 mhz when I switch it back on the
frequency comes up at 88.00 mhz for the first 5 - 10 minutes, it then slowly
creeps up to 88.5 then 88.10, it does this on all stations stored.

Does anyone have any ideas about this

Thanks
Gary
