    There is no battery compartment. Our model is actually a Radio Shack Pro 508 (20 Channel) Scanner. Electric only.

Check your manual to see if there is an internal battery. Many devices use an internal Lithium battery to retain memory. Like any other battery, after time, they will go bad.

The older programmable scanners used to use a 9V battery to retain memory. There was a plate on the back to gain acces to the battery. The newer units may have a long-lasting lithium battery inside.

Please let me know if I can be of futher assistance to you.

Good luck!

    There has to be an internal battery or large capacitor to retain memory during a power failure. See this link on Radio Shack's website:



    http://support.radioshack.com/support_el...



    Specifically:



    "The memory backup circuit begins to function a few minutes after you plug in the scanner. If a power failure occurs or if the power cord is disconnected, this circuit retains information in memory for about 1 hour."



    The failure is with the memory backup circuit. It doesn't sound like the memory is being written into non-volatile memory, other wise it would be retained indefinitely. Therefore, there has to be a rechargeable battery or capacitor that is retaining the voltage for a period of 1 hour on the microprocessor.

  2. 2. Press and hold the "TUNE/CLEAR" key and stick the end of a paperclip in the reset hole and hit the rest button.
  3. 3. Now remove the paperclip off the reset button and wait for the display to turn back on.
  4. 4. Now release the "TUNE/CLEAR" key.
  • The scanner is no initialized and ready to be programmed again.

  • Now program the scanner.

  1. 1. Press "PGM" key.
  2. 2. Now enter a channel you want to store a frequency.
  3. 3. Press "PGM" again.
  4. 4. Now you will be on that channel.
  5. 5. Now enter the frequency you want to program and don't forget the decimal.

Does the Uniden BC 148XLT have a memory battery in it? When I unplug the scanner from the wall outlet , it looses all the frequencies. Also if you know what size it takes, would be...


Sorry, but maintaining memory in your BC248CLT is not as simple as replacing a battery. Your scanner has a capacitor-based backup system, and the capacitor has apparently failed with age. Unless you're skilled at electronics repair, or you have a buddy who is, repair of this classic (circa 1999) scanner will set you back about $100. That makes repair impractical, so you might want to keep your current scanner powered up, and start looking for a replacement. Good deals on used scanners can always be found on eBay, but be certain that you know what you're buying, what condition it's in, and what it's worth.

I cleared my pro-82 scanner. Program button is not working to let me reprogram. Help.


As long as all frequencies have been cleared, try initializing the scanner. This will return everything to the original factory settings.

To INITIALIZE:
- Turn the scanner OFF, then switch it back ON.
- Hold down the TUNE/CLEAR button.
- While continuing to hold the TUNE/CLEAR button down, insert a pointed object such as a paperclip or the tip of a pen into the RESET opening on the side of the scanner, and press the RESET button inside the opening. The display should go blank.
- When the display comes back on, press the TUNE/CLEAR button again. The scanner should now be ready to accept programming.

How do you set up the scanner to scan police and ems channels


First you'll need a list of frequencies to program. For a comprehensive database of active frequencies in your area, visit:

www.RadioReference.com

Once you've selected your frequencies, power the scanner ON and

1. Press E/PGM to enter the program mode (the scanner turns on the
PGM icon).

2. If the current channel is not the one you want to program, enter the
memory number then press HOLD.

3. Enter the frequency including the decimal point, then press E/PGM.

4. To program the next memory, press  or  and repeat step 3. To
program a different memory, repeat from step 2.

5. To exit program mode, press HOLD or SCAN or change the scanner’s mode.

Notes:
• Any frequency you program replaces the previous memory contents.
• If you enter a frequency you have already stored in a different
memory in Step 3, the scanner beeps and displays the channel
where you have previously stored the frequency. If you want to store
the frequency anyway, press E/PGM a second time in Step 3.
• To clear the contents of a memory, enter “0” in Step 3.
• Channels you program are automatically unlocked (see
“Locking/Unlocking Memories) and have Delay turned on (See
“Setting Channel Delay”).

Uniden bearcat scanner


The scanner was probably turned off and it forgot what frequencies were programed into it. Older scanners have a problem with retaining their memory when they are shut off. Most of the older scanners have a memory back-up battery that helps the scanner retain its memory. Check and see if this battery is still good. As for your frequencies, you'll have to reprogram the scanner. To put it in technical terms, some older scanners have what is called RAM (Regency Alterable Memory) and ROM (Regency Organized Memory), when you turn off you scanner, this memory is erased, along with your programmed channels. Be sure not to turn off your scanner unless you're willing to reprogram the scanner.

Looses frequencies when programmed


if it loses the frequencies immediatly then it sounds like the capacitor that holds the charge for the memory has gone out. If it is sitting for a few days and loses frequencies this is more common. Solution, if you've had it less than a year, take it to your local radioshack, try to find the receipt and have them send it to the repair center for you.
