continual beeping until unplugged
Will not stop making high pitched beeping until it is unplugged.
Please give instructions.
It has never been used with batteries.
Here is a link to the user guide for your clock/radio.
Try operating the Alarm On / Off button and see if this stops the alarm. (beeping)
Here is a link to the relevant page in the manual. See the using the Alarms section halfway down the page.
Also the batteries are there only to maintain the clock and the alarm settings in the event of a power failure. They cannot run the radio. You need to have the adapter plugged in all the time. There is a battery indicator icon in the display that shows when the batteries are low and need to be replaced.
Hopefully this is of some help.
