Will not turn on

I cannot get my 2 year old unit to turn on or respond. I've tried to reset by unplugging and removing the 9 volt battery. That worked once, but not anymore. What's going on?

The alarm display in the lower right corner on model #RC40-A keeps blinking and will not stop. This happens with both wake 1 and wake 2 options. I fixed it once by unplugging the unit but it this did not...

Just reinstall the battries and adjust the time once again.

Battery back-up operation

* This clock radio is equipped with

a memory holding system that can

be powered with 2 "AA" batteries

(included). The power failure

protection circuit will not operate

unless battery is installed.

* When normal household power

is interrupted, or AC line cord

is unplugged, the batteries will

power the clock radio to keep

track of time and alarm settings

programmed into memory.

* When the battery backup functions,

the digital display will not light,

however, the function of alarm

still occurs during the power

interruption if remaining battery

power is adequate.

* Normal operation will resume after

AC power is restored so you will not
have to reset the time or the alarm

To install batteries:

1* Remove battery compartment door

(located at the bottom of the radio)

by applying thumb pressure to the

tab on battery door and then lift
the door out and off the cabinet

2* Insert 2 AA batteries (included).
3* Replace the compartment door

Replace batteries every year.

Power is fed to the unit even

when it is not functioning. To

cut the power supply off, the
power cable must be unplugged

Battery replacement in Xantrex XPower Powerpack 600 > 600 watts 12 VDC >...

Battery replacement will require opening the case of the Powerpack 600. The four rubber feet must be removed first (Phillips head #2 screwdriver). Next the two orange handle halves come off starting on the radio side. The screw heads may be either 9/32" or 1/4" heads depending on age of your Powerpack 600. Use either a 9/32" or 1/4" nutdriver to remove the screws. The orange handle halves swing open like a clamshell at the carrying handle and lift off. The orange handle half on the flashlight side has two hidden latches in the handle area that must be released with a flat head screwdriver first before that half can be fully removed. Now that the orange handles are out of the way, slip off the bumpy rubber handgrip from the gray handle. On the radio side of the gray plastic case are 9 Phillips head #2 screws that are in recessed holes to remove. Once those screws are removed, the gray plastic case seperates in half and you can unplug the two pin connector going to the radio and set the radio half aside. You are now inside the Powerpack 600 and can replace the battery if needed.<br><br>Replacement 12 volt, 28ah battery numbers:<br>Sealake # FM12280<br>Zipp Battery # 12V-28AH-T3<br>CSB # GP12260<br>Powersonic PDC-12260<br>Tempest # TD28-12<br>Panasonic LC-C1228PG<br>Universal Power Group # UB12260<br>BB Battery # BP28-12

My memorex quit playing all sound

  1. Unplug the unit and remove the batteries, wait 5 minutes, plug the unit back in and install the batteries.
  2. Check the male end on the iwake and the female end of the ipod for damage, if you are using an ipod it sounds like you may have a bad connection.
  3. Check if the Radio function plays sound.
  4. Make sure the Volume is not turned down.
  5. Does it play through the headphone jack? If so, your speakers may have failed.
  6. Most likely this will need to be sent in to Memorex, or a new unit will need to be purchased.

Clock runs 5 minutes fast

Do you mean you set the correct time initially and then gradually got faster?There may be a reset button on it somewhere,no guarantee.It will probably be a small circle that doesn't look like anything.If there is,press it with a sharp pencil or something just as small.If not,it's just the nature of the beast.I have a radio which slows down over time...and it's a BOSE wave radio and have to adjust periodically!That's about all you can do is deal with it.Sorry if you can't fix it. Good luck!

I have a very old Bose clock radio (model AWR1-1W) that has suddenly deceided to light up every single character on the display solidly. Unpluging and plugging it back in does not help. Any ideas?!?...

Hey Pete! Did you take out the 9V battery as well and let power down to re-set? Benimur from JustAnswer suggested: Your described problem could either be a system glitch, hardware fault.
If it were a glitch, unplug the unit for an extended period of time to force the Bose to reset and revert to factory defaults. This would also require removal of the 9 volts battery. Should this be not corrective, then it would seem that the logic circuitry of the Bose radio is faulty. The logic circuitry includes the micro processor that handles all the controls and the displays. Unfortunately, not a user doable repair.

My 10 year old Bose wave radio quit working.

There's a line fuse inside the radio, mounted on a PC board. CAUTION: disconnect the set from power before opening the case or poking around inside. The fuse could be bad, but these sets are notorious for losing the power transformer. If the fuse is ok then you are looking at a $100 repair fee from Bose. You might want to check out the new HD radios -- better sound, MUCH lower price.

How to set a RCA RP3720A model

First, move the slide switch at the left rear of the top of the unit all the way to the right. You'll see the colon blinking, indicating that you are in 'set' mode. Now turn the dial that surrounds the ON/OFF button on the top of the unit. You can move it clockwise or counterclockwise, to change the time forward or backward. When done, move the slide switch back to the far left. Done.

Magnavox CD Player Clock Radio not working

This Clock/Radio/CD player has had component failure problems. The unit is probably not worth repairing. The reason is the parts and repair information is probably very limited. The cost of the repair with parts and labor will be expensive. This repair would probably cost you more than just buying a new Clock/Radio/CD player. I hope this information helps you with your problem. Thank you for using FixYa and have a nice day!
