PRO-94 Memory Loss "BACKUP BATTERY??"

I own a PRO-94 and once in a while the scanner loses all of its memory and resets. Well, I thought maybe its something minor. Then, a buddy of mine gave me his to fix due to the same issue. I opened the whole scanner up from top to bottom and figured it must me a backup battery issue. Just replace the backup. Well, does this scanner have a battery backup because I found nothing inside of it, that was a battery backup. Where in the world is it?? Does this model not have one?

This sounds like you're monitoring an EDACS system and are not in trunking mode (search or scan). EDACS systems transmit those tones to make scanning less enjoyable. Read the manual to find out more about programming and monitoring trunked systems.

SOURCE: my pro 2096

I have same problem. First unplug and then turn radio on to clear any left over power. Open the radio by removing 4 screws on back, then 4 more screws to remove top of inner case. then you will see a white ribbon cable. This has either come loose or it is not lined up properly on the connector. There are tabs on each end of the connector, you will need a super tiny screwdriver like for use on eyeglasses to open the tabs. Slide them towards the display or front of radio to remove the ribbon cable. I then used some alcohol and a q-tip and cleaned the metal contact point. then I slid the cable into place, and being careful not to touch anything inside radio, turn it on and check display. It took some moving around for me but finally got it to come back. Then close tabs on connector to hold ribbon cable in place. It seems to be a common problem with this radio.

SOURCE: Battery holder for Pro 95 scanner

Your pro 95 takes the same yellow rechargable battery pack as the pro 97. It is available at the site listing below. It is their #100-006. It cost 5.99 plus 10.95 shipping. I ordered it 4 days ago and got it two days ago. You may be able to save on shipping by calling them and requesting some sort of slower shipping.

SOURCE: MY pro-94 said on the screen lu,red or something like that !

Could the display be saying "wired"? This is what it shows when it is in cloning or programming mode. If it is showing this and there is no programming or cloning cable attached, check the programming jack to see if it is damaged.

How to clear all my frequencies from my portable scanner

To clear all information that you've programmed into the scanner you can perform a RESET to original factory settings:

1. Turn off the scanner.
2. While holding down the 2 and 9 keys, turn on the
scanner. CLEAR flashes for about 5 seconds as
the scanner clears its memory.
Note: Do not turn off the scanner again until CLEAR
stops flashing. Otherwise, the scanner might not clear its memory properly.

I have a radio shack pro 94 scanner that gets stuck in the high channels. How can I make it scan to other channels

Getting "stuck" indicates that the scanner may need to be reset to restore proper operation. This is a fairly drastic step that will erase ALL information that you've programmed into the scanner, but it's about the only fix. To reset the PRO-94:

- Turn the scanner OFF

- While holding down the 2 and 9 keys, power the scanner ON.

- CLEAR will flash for about 5 seconds as the scanners clears its memory and restores factory settings. Do not turn the scanner OFF or press any keys until the CLEAR message stops flashing.

No telling what he did, but if you've tried deleting his entries and the scanner is still locked up, you'll need to reset it. This procedure will clear all the information you have have stored in the scanner.
1. Turn the scanner OFF.
2. While holding down the 2 and 9 keys, turn the scanner ON. CLEAR will flash for about 5 seconds while the scanner clears its memory.
NOTE: Do not turn the scanner OFF until CLEAR stops flashing.

Scanner says WIRED when i turn it on, and it won't do anything

A RESET may clear the problem, but it will also erase all frequencies and data that you've programmed into the scanner. To RESET the PRO-94,
- Turn the scanner OFF
- While holding the 2 and 9 keys down, turn the scanner ON. CLEAR will flash for about 5 seconds as the scanner clears its memory and restores factory settings. Do NOT turn the scanner OFF until CLEAR stops flashing.

How do i replace the memory backup battery on a Symbol mc3090? The memory backup battery no longer takes a charge, changing the main battery results in loss of all setup features and programs. After a...

Hi Ken. Replacing the memory backup battery (flash/BIOS battery) on any unit is tricky to say the least. I would implore you to check and see if your scanner is still under factory warranty with Motorola/Symbol then send it in for the repair. If it's not, I would have a chat with the vendor you bought it from; a lot of times they will do little repairs like that for a reduced price since you are a customer (I know I do). If both of those fail: the BIOS battery is on the main board of the unit. To get to it you will need to remove the outer shell and then start removing components until you get to the board and the battery. Again, unless you are very experienced with electronics like this (maybe even PCs) and really confident in your abilities, I really would recommend having a professional do this. I would offer to, but our repair facilities won't be up until February of this year. If you need some suggestions on where to go or need to troubleshoot more, please feel free to send me a message or email me at I hope this helps. Good luck!

Backup battery

The backup battery exists to protect your data when the main battery dies. It only has enough power to keep the internal memory 'alive' so you dont lose your files, settings etc.

When the backup battery dies it should be replaced as soon as possible, as the main battery will power the internal memory only while it has charge. Should the main battery die it would be like performing a hard reset.
