I just read the manual an I am not sure it does. The manual says nothing about that. My clock does the same when power fails. Comes back to correct time when power returns. I miss that on my older clock. Display never went out even during power outage. You can call Phillips an ask or email. It is on there site.

Wall scoreboard clock model #0028 not working after outlet blew


Remove several screws around perimeter of clock. Open up clock and find small (quarter -sized) battery. Remove this battery - it may be hot glued in place but you need to remove this. You don't have to replace it just remove it. Apparently this battery is used when you have a power outage to retain date / time, but when it goes dead it won't allow the clock to operate. So just remove it and put the clock back together and all should be fine except you will have to reset the date etcetera when you have a power outage.

They're just used to retain memory. That's all. Once power comes on, the time should be correct. Now if the power went out and there was no battery on the clock, when the power comes back on it goes straight to flashing 1200.

Which the voltage of the transformer to be replaced


Hello
Your clock has a backup battery. Battery is for time backup only.

The clock and alarm memory will

be retained during a power

interruption. During battery

backup operation, the display

will not light up, but the correct
time will be maintained internally
The mains transformer inside it will be of 10.2vAC secondary to 120VAC primary. OK.

This AM it started blinking and will not stop It is less than 1 yr.old.


Sorry it took so long to reply to your question. This look like a problem with the Clock/Radio's Microprocessor. You will need to reset the microprocessor by removing all power sources to the microprocessor. This means removing the Clock/Radio from the A/C power source and removing the internal battery (CR2430). After removing all the power sources from the Clock/Radio, let the Clock/Radio set for a period of about 3 hours. This will let the power completely drain from the microprocessor and reset it to the factory settings. You can then reinsert the internal battery and plug the Clock/Radio into the A/C power source. The Clock/Radio should have reset and the functions returned to normal operations. If The Clock/Radio functions have not returned to normal. You will need to let the Clock/Radio's microprocessor drain off the power again and put a new internal battery (CR2430). Then test the Clock/Radio's functions again. The Clock/Radio functions should have returned to normal operation. If you are still having problems getting the Clock/Radio to return to normal operation. You can call the Emerson customer support at this telephone number 1-800-909-1240- Call them between the hours of 8am to 4:30pm central time USA. Give them the make and model number of your Clock/Radio and ask them for their assistance. I hope this information helps you with your problem. Thank you for using FixYa and have a nice day
