Sony ICF-CDK50 (under counter kitchen clock radio) just installed, everything works fine except for sporadic intermittent beeping (3 to 5 beeps). Instructions give no clue as to cause or solution.

If there is no FM Antenna connection you can try to move the power cord to different positions and see if you get a better signal. If not then move the unit closer to a window or try various locations that might have better reception.

Download its user manual from here and refer it for details.

Hello
Unplug the unit and replug it after 5 minutes or so. Then Hold Down the CLOCK/DATE until a short beep sounds. If this beep sound cannot be heard, be sure that the internal circuit has some trouble, and has to be repaired. Normally, any other button get strucked, there will be no response with other buttons. OK.

Look in the user guide...

It has NO outputs whatsoever but it DOES accept the audio from another device's headphone jack through its own stereo miniplug.

The solution is to toss it because it can't be corrected. I gave up on mine after a month and threw it away. Somebody should have told the genius that designed this radio that a kitchen cannot be rotated to achieve a radio signal. Maybe a way to rotate the internal antenna or a way to connect an external antenna would be helpfull. So much for technology. When you pay a premium for a respected name like Sony, you expect more. I replaced it with a cheap Coby at less than half the price and it works fine

Mains transformer output volts are 12V AC for Sony ICF-CDK50
Circuit location is T901 and part number is 143591722 .... TRANSFORMER, POWER (US, CND)
Hope these info will help you.
Thanks.

This is the original manual. Put just hold down the clock/track button until it beeps.
