Question about Proton R5A Clock Radio

Open Question

Proton P300 AM/FM Radio

Does anyone have a wiring or circuit diagram for this radio. In addition can the 110V AC radios be simply converted to run on 240V AC

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,

- Phil

SOURCE: Proton 320 clock radio won't stay off. Comes back on by itself!

check power switch if not block and i good position. and also monitor by multitester if the continuity of that switch cut in off position.

SOURCE: I have a proton 300 table radio and it has very poor reception.

I had this problem too, and fixed it by repeatedly and rapidly cycling the radio between AM and FM. Those buttons on top of the radio collect dust, which gets down into the mechanism and causes poor contact. Pushing the AM/FM button a bunch of times restores the contact. However, in my case this problem was an early warning of other problems to come: phantom turn-ons, etc. Eventually you'll find it necessary to take the unit apart and REALLY clean out all thos switches. I'm at that stage now.<!-- from fixya rte -->

I simply cleaned my red switch by spraying it with tuner cleaner and the problem went away (it will return in a few years and cleaning it will correct it again). The switch can only be cleaned with the radio open. A can of tuner clean/lub with a small straw will be needed.

SOURCE: My Proton 320 radio has stopped working, although

Unfortunately, Proton discontinued these a very long time ago. There is not very much information available about them. The cause for the radio malfunction could be a number of things. One possibility is the switches. There is a foam gasket around the switches that degrades over time. If pieces of it get stuck inside the on switch, or lock the off switch, it would prevent the radio from working. You could try taking it apart and use a can of compressed air to clean out the switches. I had a problem with the radio turning on all by itself and the compressed air cleaning solved it.

Are we talking a new deck/stereo or new speakers/subs?
A new deck will require a wiring harness (cheap at walmart or local auto place) and this will come with a set of directions and wiring diagram for your make/model vehicle.
Subs/Speakers can be wired into a stock AM/FM radio (though I have no idea why anyone would want to do this) fairly simply, The wiring diagram will be printed on one side of your stock radio letting you know where to attach the 12v constant, the remote wire, and the speaker wires.

The original problem that damaged the internal transformer was not resolved. The transformer may be damaged again - it is used in the AC circuit but not in the battery. They are two different circuits. The red led is part of the AC. I would contact Dewalt and send it back explaining what happened. The part they replaced should be under warranty.

There may be extra wires you don't need. The basic set of wires on the radio is 4 pairs of colored wires--one black-striped and one plain for each speaker. Yellow is usually accessory power, red is hot, and black is ground. Some additional wires may be one for a power antenna, one for an external amplifyer, and one for facelight (in case it will run on dimmer)
The car should have the following corresponding wires:
Radio 12v--- orange
Radio Ground--- black
Radio Ignition--- yellow
Radio Illumination--- brown
Dimmer--- gray
Power Antenna--- pink (if you have one)
LF Speaker +/- tan - grey
RF Speaker +/- lt green - dk green
LR Speaker +/- brown - yellow
RR Speaker +/- dk. blue- lt. blue

The car or radio could have additional connectors, such as for a subwoofer, CD changer, etc.

The FM tuner picks up only a few stations and those are very faint. Two other Proton model 320 radios work fine in the same area. I live on Long Island where the reception is rather strong.


The tuning module within the radio is getween the base circuit card and the display. A shot of tuner cleaner into one of the ports will usually bring back the FM performace (I just got done diong my own). Also, it goes without saying that you need to make sure your radio still has its antenna wire and that the vacuum didn't eat it. If this is beyond your skill level, find a computer geek (there are few radio geeks any more). Commercial repair would cost more than the value of the radio.

Want to change my 110v plug on my dewalt radio to 240v


Your radio must be a import from the U.S.A. Your radio will not work on 240v YOU WILL BLOW IT UP!!! You need a step down transformer 240v to 110v to goto your radio, you will have to do a search on Ebay in Power tools. You sould notice the lead on your 110v radio is not like normal flex as its only single insulated for 110 volts.... Don't put a normal plug on or you may have to call the fire brigade!!

Questions:
1. Does the AC cord look ok? Not damaged?
2. Have you tried another AC outlet?
3. Does the AC cord unplug from the radio?

When you operate the radio from the AC power cord, the radio uses an internal power supply consisting of a step-down transformer, rectifier, and filter that converts the AC to DC to operate the radio.

When you run the radio off of batteries, it powers the radio directly. In some radios, when you plug the AC cord into the radio, it activates a switch that disconnects the battery voltage to the radio so that the batteries wont be damaged from the voltage created by the internal supply.

The radio can be powered by either the batteries or the internal supply. You don't want either supply affecting the other, so that is why a switch is sometimes used.

Since the radio works fine off of batteries, that would indicate that there is a problem with the internal power supply. This could be a blown fuse, bad transformer or bad rectifier diode.

Good Luck,
- Jim
