Your Profex likely has a dead NiCD battery. You are getting this error because this battery maintains your personal effect settings on an SRAM chip that requires constant power to "live". You can try reinitializing the SRAM on your unit by doing the following:

1. Power off your Profex.
2. Press and Hold the "PLAY" and "GLOBAL" buttons while powering the unit on.
3. You should see a message on the display that reads "MEMORY INITIALIZED". Afterwards the Profex should act normal.
4. If your internal battery is getting low or is already dead, it is going to start leaking (if it hasn't already). YOU NEED TO GET THAT BATTERY CHANGED NOW!!!!! If enough battery acid leaks onto the circuit board, it will ruin your Profex forever.

    Thanks! I had exact same problem with a ProfexII. After replacing corroding internal battery and cleaning up the circuitboard, I also recieved this message. After the re-initialize it works great!

What is wrong with my pioneer pdpro6u media receiver?it shut off and wont power up,and there is a blinking blue light what does it mean?


  • there might be speaker wires touching somewhere
  • check all ventilation slats in Receiver make sure dust free
  • Check all connections maybe cable connections mixed up
  • Make sure power cord plugged in all of the way. Also make sure that the cord does not have exposed wires (this could cause a short
  • Make sure the wall outlet you are using is not overloaded (Too much power being used)
  • If this problem persists call customer service

Want to use my current speakers with a new surround sound system. Current system is 5.1 channels, rated at 100w per channel @ 8. Ohms. New System is rated 145watts, 5.2 channels at 6 Ohms. Will b ok?


Hi Ronald.
8 Ohm speakers will work just fine as replacements for the
6 ohm speakers. When fitting speakers you need to consider
The power handling capability. The impedance and the frequencies
involved. Power handling is expressed in wattage ie 100W.
Unfortunately this can be expressed in rms, max or peak music. The rms value (root mean square) is the only really relevant figure as this is the continuose handling power at 1 KHz. The impedance
is the resistance that the amp sees but is not a dc resistance and
varies with frequency. The lower the impedance the more power
will be drawn from the amp. In the event of a short circuit across
the speaker the amp will try to deliver infinite power into an infinitly
small load in an infinitesimal amount of time and will self destruct.
Using an 8 Ohm speaker draws less power than a 6 Ohm speaker.
Connecting speakers in parallel; results in the impedance beingreduced. For example two 8 Ohm speakers in parallel will result
in a 4 Ohm impedance load but in series will be 16 Ohms.
Incidentally the the .1 (5.1) is the sub woofer which only has
to handle the bass frequencies, a small percentage of the
amplifiers overall frequency response..
Connect your speakers and then power up the amp last
after double checking there are no shorts on the speaker
cables.
All the very best from Vintie.

Altec Lansing 2100 Controller. My controller's power button is intermittently not working. Anyone know if this is an easy fix or have a controller to sell?


Test the remote control for its infrared emission. To get more details about how to check a remote control, visit the site linked here.

Switch on akai58022 tower speaker, it worked when I got it today and now it wont even switch on


what do you have it plugged-into for power ? it uses the 8-pin Apple Lightning dock connector. If you are using a USB adapter for that, then be aware that a USB-port will only let you draw 500mA or 1/2 an Amp of power....more than that will cause failures and damage to the USB port and the Hub even.

I have a 1970's Panasonic Flip Clock Radio. (Model RC6530) The radio works just fine, but the flp clock stopped flipping. There is power going to the unit. I can also hear a low hum from the flip...


It looks like your problem might be an easy fix, at least. If the gear train between the motor and clock got stripped, you'd be in a bit more trouble. If the motor just isn't spinning, remove it from the side of the clock housing. There are 2 screws (or nuts) holding it in place. When you get it off, the cover for the motor will also be off. Apply some 3 in 1 oil, or perhaps just a tiny bit of penetrating oil, and give it a spin. From what I've read, it should do just fine. A lot of people use wd40, but I understand that can gum up over time.

This is a "at your own risk" type of repair, but as long as you unplug it before dismantling the radio, I think you'll be fine.

Your radio should have come with a receiver of some sort for the radio signals to set itself. I had this same issue with my clock when the battery in the receiver died ... try replacing this too. It took me forever to figure out what it was because I had forgotten that it had its own radio receiver ... then once I remembered it existed, I had to find it, but replacing the battery fixed the problem. Hope that helps :-)

BOSe Wave Radio - Disk "not readable"


I had the same problem with the disk unreadable error and took my unit to a authorized repair dealer about 100 miles from where I live to have it fixed. It ended up costing me about $300 to have the CD unit totally replaced which is almost as much as I paid for the unit in the first place. I am like a lot of you that used the CD very little although the unit was about 3 years old. I think Bose has a problem and would like us to think it is very rare. I bought a Lifestyle surround system about 14 years ago that has a CD and have never had a problem with it so needless to say I am very disappointed in the Wave II Radio/CD system. I am fairly certain the problem will occur again, but only time will tell.
