HOW TO CHANGE ALARM FROM BUZZER TO 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.

You have to hold the "time button" while pressing the min & hour buttons to set it, and if your trying to set the alarm you hold the alarm button

Contact Dealer or Authorized Service Center.

there are 3 buttons just above the above the LCD clock - Alarm Set, Radio, and Buzzer. When you press the Radio button you will see the word "radio" appear/disappear just below the time with each press of the button. You want to press this button to make the word "Radio" disappear. The same is true for the Buzzer button. Press the Buzzer button so that the word "Buzzer" does NOT appear below the time. If you do not see the word Buzzer or Radio below the time, then the Radio Alarm and the Buzzer Alarm are both OFF and will not sound.

Press the Buzzer alarm button until its indicator on the LCD display goes out. This should defeat that alarm. For your interpretation:

Be sure the radio is set to off or standby.
Hold down the alarm button (#1 or #2) until the disply begins flashing.
Use the TUNER/CLOCKSET dial to change the display to the time you want the alarm to go off.
Press the alarm button briefly to return to normal operation.

When you set the alarm you pressed aburron that said 'radio' and/or 'buzzer' then programmed the time. Just press the buttons again and the alarm will no longer sound. Looking at the dial at the top of the lcd screen you will see the word buzzser or radfio if the alarm is enabled. Pressing buzzer or radio on the side will remove the word and no more alarm!!
