Question about Sony Walkman SRF-M37V AM/FM/Weather/TV Radio
There is no internal battery on the Sony SRV-M37V. Presets are held in non-volatile RAM and don't need power to maintain the settings.
Your problem is that the hold switch is not disengaging. Either the contact below the switch has gotten gummed up and won't release, or perhaps the switch is broken.
You can try spraying a tiny (very tiny) amount of Contact Cleaner (available at Radio Shack for less than $5) into the switch. Or disassemble the unit to see why the switch isn't making contact like it should. Hope that helps!
