JCR-160 clock radio Clock running slow

Jensen JCR160 digital clock running slow Tried JCR160 with 120v to 220v convertor in India found the clock looses 5 secs for every min. Tried replacing 110volt input transformer with different 230v input transformer found no change. Tried rewinding the primary side of the original transformer without disturbing the secondary winding & the voltage output still no change. Any solution available ?....

    I also face the same problem
    I use MAGNOVOX MCR140/17 clock radio. The product is excellent but the clock runs slow when used in India as the electrical frequency is 50 Hz compared to 60 Hz so I dont know what to do now.

There is an option to choose 50 Hz or 60 Hz in main IC. Open the radio clock and see the number of IC. Download datashee of that IC and see for selection of 50/60 Hz. You have to just short the desired pin.

The clock works off the frequency (hertz). In US the electrical wave frequency is 60HZ/sec and in India and many other countries 50HZ/sec. Hence, the clock slows down about 6 seconds or so every minute.

Instructions for jensen jcr-425 clock radio, how to set clock


To preset a channel on the JCR-425, you tune in the channel; press the "AL/MEM" button on top of the radio (at which time you will probably be switched to some other radio frequency, which is rather disconcerting), press the "Up" or "Down" button to select the desired preset channel number, press "Set" -- and only then are you returned to your desired radio station. If you want to preset several channels,
You might then think that the next time you turn on the radio that all you would have to do is press one of the 10 preset channel buttons on the front of the radio to visit one of your preset radio stations. You would be wrong. You must turn on the radio, then press the "AL/MEM" button on top of the radio. Only then can you access your preset radio stations.
You might also think that to turn on the radio you would press a button that says "Power." Wrong. You press a button that says "Radio." Well, okay. But you might think that to turn it off, you would just press the "Radio" button again. Wrong. If you have pressed the "AL/MEM" button to access your preprogrammed channels, pressing the "Radio" button simply takes you out of the "AL/MEM" function and back to the "FM" (or "AM") function, apparently taking you back to the last radio station you tuned in manually. To turn off the radio after accessing a preset channel, you must press "Radio" twice.

There is a display button on the unit, if that does not dim the display, there is almost nothing you can do

NEED HELP SETTING THE TIME


i had the same issue; with a little bit of experimenting I was able to set the time. Hold down the stop/time button until it displays 12A (it might display 24H first - do it again if you don't want military time to get the 12A) Let go then press stop/time again so the time blinks. Use the hour and minute buttons to set the time appropriately. When satisfied, press the stop/time button again.
