Question about Proton R5A Clock Radio

Proton Model RS-420 clock radio lost power back-up

Radio works fine except the power back-up function has ceased to operate - was OK for about 12 years. Now, whenever there is a power glitch (even for a millisecond) it looses the time and all presets. A real chore to reset ever time and if the glitch occurs during the night I don't get my wake-up music. What component has gone bad? Can you specify it and its location so I can get a new one and replace it? I have never opened up the case since I purchased it. Proton Radio Model RS-420 and S#RS420008283

    Same problem. No battery backup but original box says built in rechargeable battery. Also, I need to recall how to set what radio station comes on when you use the alarm. email me at [email protected] if you have the answer. Thanks

    Yes the back up battery has lost its ability to holds a charge, I need to find the circuit boad power supply and replace the batter. Anyone with a schematic on the curcuit ?



    Note, the alarms (both) default to the last station tuned to from the normal operatoin tuning, not the pre set keys.

    Same problem - loses settings after power outage (and boss is getting pissed about me showing up to work late ;)).

    I just opened up my unit, don't see anything that looks like a battery. Any help here available?

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,

- Phil

    My battery is a Varia 11DK, and you could read that other number as 098 or 860. Have you come up with a replacement yet? It's too good a radio not to fix. Thanks

I changed out my battery. Now my radio is not working. Fuse is OK. Ideas?


Most newer cars have a feature that if power is interrupted to the radio (blown fuse, battery disconnect) it will cease to function without the insertion of a reset code. This code is usually on a card in the owner's information package. IT is intended as an anti-theft precaution, since without the unique code, the radio is worthless. If you don't know the code, or didn't receive it, a dealership can usually provide it if you can give them the serial number of the radio. This will, unfortunately, usually involve the removal of the radio to obtain.

It just froze and it stop working i reset it but it is frozen (bv7300 car dvd stereo)


Ok, a little more description is needed to help. When you say "froze", do you mean a dvd image froze on the screen or do you mean that all functions have ceased to operate. If you reset didn't work, you will need to old school it. Remove the radio from power completely for about 15 minutes and then reinstall. See if that helps. The other variables are how long you had the equipment, did you purchase new, did you buy from someone else, did you install or have it professionally installed. These are things that can help with warranty issues too. Good luck.

Hello
Just reinstall the battries and adjust the time once again.

Battery back-up operation

* This clock radio is equipped with

a memory holding system that can

be powered with 2 "AA" batteries

(included). The power failure

protection circuit will not operate

unless battery is installed.

* When normal household power

is interrupted, or AC line cord

is unplugged, the batteries will

power the clock radio to keep

track of time and alarm settings

programmed into memory.

* When the battery backup functions,

the digital display will not light,

however, the function of alarm

still occurs during the power

interruption if remaining battery

power is adequate.

* Normal operation will resume after

AC power is restored so you will not
have to reset the time or the alarm

To install batteries:

1* Remove battery compartment door

(located at the bottom of the radio)

by applying thumb pressure to the

tab on battery door and then lift
the door out and off the cabinet

2* Insert 2 AA batteries (included).
3* Replace the compartment door

Replace batteries every year.

Power is fed to the unit even

when it is not functioning. To

cut the power supply off, the
power cable must be unplugged
OK.

Cant get Pointer to move


First try
Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it. This should connect the mouse to the receiver and work properly. If not, try pressing the receiver button and then press the button on the mouse. This should be done whenever you change batteries or glitch.
Then if that doesn't work try
Normal 0 Turn the mouse over and find the small rest/connect button on the bottom of the mouse and press it. This should connect the mouse to the receiver and work properly. If not, try pressing the receiver button and then press the button on the mouse. This should be done whenever you change batteries or glitch.
Hope this helps you. Bud
