Query IC-2350
 

Hello
I have an ICOM IC-2350 xcvr 144/440 rcv 900
After every transmission while receiving there enters a tone
I did as per instruction on Start-up hold said Set-Lock Switch
and change the setting to No Beep
It still Beeps in a lazy fachion Like intermittently at times
Now Is there a Mem Battery that needs to be replaced ??
Has anyone else encountered this I say problem ???
Thank you for reading my query
