Can't disable alarm feature on colock radio

Can you comment with the model number? It will be on the information sticker on the radio itself. It will possibly start with 'CRX-'.
Try this - Press and hold the alarm set button until the display flashes like your setting the alarm time. Click the same button again and it should swap between buzzer and radio each time you click it. It will probably show some sort of logo on the display telling you which it is set to.

SETTING THE WAKE TIME You can select two different wake times for music or alarm to turn on automatically. WAKE 1 and 2 controls are located on top of the unit behind the SNOOZE bar.

1. Slide switch to SET position. The display will change to wake time.
2. Use the FAST FORWARD, FORWARD and REVERSE buttons as needed until you reach your desired AM or PM wake time. For music, select an AM or FM station and then turn the radio off. Set wake time and then slide the switch to MUSIC. For Alarm, set wake time and then slide switch to ALARM position. If a wake time is set, an indicator in the display lights and the unit turns on in the chosen mode (alarm or music) at the set time for approximately one hour. To turn off the wake mode, slide the switch to OFF or press the OFF button. NOTE: If both Wake 1 and Wake 2 controls are in the SET position, the time of day is displayed. GE 7 4825 User Manual

Either the electronics are fubar or the noise making device is no good. Gotta checkout which is ng.

If it has a wake button, push and hold the wake button while you push the hour and minute buttons to set the time to wake. It may have an alarm button instead of a wake button. Then there should be a switch to set to wake to alarm sound or music.

The manual says to "DISABLE THE ALARM PERMANENTLY" you should:

"Press and hold WAKE 1 or WAKE 2 until the green indicator disappears."

I did this and the light indicator to the right of the clock digital readout went out after a few seconds. I won't know until tomorrow if the alarm is permanently disabled.

On the top of the alarm clock is a CANCEL button. Press the button and the light next to the WAKE MODE indicator on the front of the clock will begin to flash. Press the WAKE MODE button on the top of the clock. The WAKE MODE indicator will go out and the alarm is off. If you want the alarm back on just press the WAKE MODE button again.

GE doesn't make this kind of product any longer but on their site they say to call 1-800-447-1700 for assistance. Maybe someone there can find a copy of the instructions for you.

Disable the alarm permanently 1. Press CANCEL button. 2. The corresponding WAKE indicator will be flashing. 3. Press WAKE 1 or WAKE 2 button within 3 seconds to deactivate the corresponding alarm function permanently.

What I have found with my alarm clock like this one is that you CANNOT be soft on it. When setting the time, hold down the F or R button extra hard. I know that seems odd, but it works!

SLIDE THE SWITCH TO TIME DO NOT PUT ON WAKE 1 OR WAKE 2 THOSE ARE LIKE TWO SEPEATE ALARM TIMES YOU COULD SET PUT ON CANCEL OR JUST TIME.
