Selecting a Time Zone
1. Press the ATOMIC ON/OFF button (Fig. 3) to turn off the atomic time function.
To indicate you are at the off position, the atomic time icon (Fig. 2) will be removed from the display.
2. Toggle through the DST/TIME ZONE button (Fig. 3) until you reach your desired time zone. (P - Pacific Standard Time, M - Mountain Standard Time, C - Central Standard Time, E - Eastern Standard Time)
3. Once you have selected your time zone, press the ATOMIC ON/OFF button again to turn on the atomic time function. To indicate you are at the on position, the atomic time time icon will reappear with flashing antenna bands. (When the antenna bands appear flashing the unit is searching for the atomic time signal.)
4. If the atomic time icon disappears afterwards, the atomic time signal is not available at that moment. Try setting the unit in other locations. Remember to place the unit away from sources of interference such as mobile phones, appliances, TV etc.
5. The atomic time icon will appear on screen if the atomic time reception is successful. (The antenna bands will stop flashing when atomic time reception is successful.) The radio-controlled clock will have a daily synchronization at 1:00 am everyday. If previous attempts of reception were unsuccessful, the home receiver will attempt synchronization each hour until successful. Each reception cycle ranges from 2 - 10 minutes.

Manual Setting of Clock
1. Press the HOUR button (Fig 1) until you reach the correct hour.
2. Press the MIN button (Fig 1) until you reach the correct minute.
3. Press the BACKLIGHT HI/LOW/OFF button (Fig 3) to adjust the backlight intensity.
Note: A PM indicator will appear in the upper left hand corner of the LCD display during the PM hours. Be sure to set the time for the correct 12-hour period - AM (morning) or PM (evening).

The original is an incandescent 14V 30mA bulb. Hard to get. Much easier to substitute a Blue or Green 3V 30mA LED, in series with a 470ohm 1W carbon resistor, to reduce the 14V to 3V. The LED will last almost forever. Don't forget that an LED is polarity-sensitive, and must be connected appropriately Long-leg to RED, and Short-leg to BLACK.

I must have pressed the wrong button on my old but excellent Proton 320 clock radio because the radio no longer comes on at the time set on its alarm. The radio is fine when I just turn it ON; it goes...


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 ..

I have a Proton car but I have never heard of a Proton radio.

As a matter of general interest, the flywheel tuning system was used on early radios before the superheterodyne system brought us agc lines and such sophistications. Selecting another station was a noisy business and flywheel tuning allowed the dial to be traversed quickly with a flick of the wrist. Those flywheels were heavy and mounted in ball bearings...

The trouble with trying to obtain spare parts for radios is mostly you can't. The manufacturer uses mostly bought-in standard electronic and hardware components and makes as little as possible, apart from the cabinet, the circuit boards and a few other bits and pieces and then will assemble what is generally regarded as a consumable item. The manufacturer's interest fades quickly when the warranty expires. Whatever (few) parts remain will be priced not to sell in order to build in obsolescence.
It is mostly expected that minor repairs will be handled by local repairers using standard parts until it becomes uneconomic or obsolete.

It might be possible to locate another plastic "flywheel" but searching would be a mammoth task. The number might not be a part number, might have been made by anyone and Proton is such a popular brand, model, type a search would not be easy.
The best alternative is to repair the original, adapt something else to do the same job or have a replacement made or devise another method of doing the same job.

Good Luck!

My Proton 320 radio has stopped working, although the clock function still works. Is this a simple fix? Where could I find a manual?


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.

Lost my 'off' ' button on my Proton 320 clock radio!


No need to worry, you can buy adjustable knobs and at radioshack and ebay. However if the button broke off you need to go in and replace it.

I have a 25 y. Proton 300 radio, which until recently has been flawless. It now reverberates and seems to have "ghost" sounds, even when sharply tuned. What's wrong????can it be fixed???where could I...


It sounds like the tuner is out of alignment. A number of things can cause this kind of problem. However, a realignment is a very costly proposition, especially when considering the used value of the Proton 320. If you really like this radio, you might want to try buying a used example off of eBay. They come up very frequently. Only... be selective. Don't pick anything from a seller without a lot of good feedback. And don't overpay ($50 tops).

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.

Tuning lamp on Proton 320 clock radio


The bulb is a small electronics bulb on the left side of the lexan display cover and it is covered with an insulated foil tape. Measure the voltage on the bulb with a voltmeter and go buy a replacement from any electronics supply place or radio shack.

How to set the clock on a 2001 Nissan Frontier


Clock set:

To adjust the clock, press the tune knob for longer than 1.5 seconds. A beep signals entry into the clock adjustment mode and
CL appears in the display. The hours will be blinking. Rotate the tune knob to adjust the hours to the desired level.

Press the tune knob a second time and the minutes will start to blink. Rotate the tune knob to adjust the minutes to the
desired level. After 10 seconds, the radio or CD display will reappear. Once the clock is set to the desired level, press the knob repeatedly until the radio or CD display reappears.

All done!
