HOW DO I SET RADIO PRESET FOR DAILY ALARM?
SOURCE: Proton Model RS-420 clock radio lost power back-up
The battery is located on the display circuit board at the front of the unit. It's a bit of a pain to get to.
You'll need to open the case, unplugging the wiring harness plugs so you can take the two halves apart. Next, remove the strip of circuit board at the top where the snooze/alarm and other top button switches are. Then you will be able to get to all of the screws holding the display circuit board to the front of the case. The battery is soldered to the board. I'm not sure what type or voltage it is, but it's probably a single-cell NiCd at 1.2v. I think the best replacement would be a supercapacitor but I need to figure out exactly what the battery is first.
It's a great radio that's worth fixing. If anyone can tell us what the battery is, please post! Mine says "860" on it.
Cheers,

The display itself may not be the problem which may be related to the power supply for it instead.
Some technical skills and a decent multimeter is the minimum you should have to determine the source of the problem.
If you are looking for a local service company, you should always post your ZIP code so a tech in your area is likely to respond.

when you set the alarm it is activating by itself ...see that you have the button that will set it to go to radio or buzzing noise..and in the back it has a knob for a separate volume on the alarm I think this is what you have lower and the alarm is not heard even if it kicks in ..
let me know if that is the issue or I should see further ..
