Question about Uniden BC895XLT Base Scanner

1 Answer

MEMORY QUESTION I have a Uniden BC 890 which is a very simular unit to the 895 xlt. I have noted that if it is unpluged for a period of time the stored channels go away. I presume the memory battery, a 2032 lithium battery is failing. I can see the battery but Uniden thoughfully spot welded the contact/retaining strap to the battery and soldered it to the circuit board.. I realize if I remove the battery for service it will cause the loss of the memory channels which I can deal with. My question is: "Will removing the battery without supplying a 3 v source fritz the operating program of the scanner or will it resume working when powered up". Is there a reset procedure to restore function? Thanks.

    This repair relates only to scanners using a memory battery. It does not apply to units using a memory that is not corrupted by loss of memory battery voltage. I am told that some Radio shack scanners use this same circuity so it should apply to them also.

This problem is caused by failure of the lithium memory battery #2032. To replace same remove top and bottom covers.Use a small pair of pliers or curved hemostats to hold the bottom of the speaker connection socket to the board as you unplug the connector. If it is not done you run the risk of loosening the socket from the circuit board. Carefully unplug the ribbon cables that connect the front panel to the main circuit board. You may leave the rest of the attached wires alone as they are long enough to permit service without removal. Remove two screws from each side of the front main frame and the single screw securing the main circuit board to the front panel board. Gently bow the front of the main frame sides inward to permit detachment of the front panel. On the bottom front of the front panel is a small flat battery soldered to the front circuit board on flat standoff legs. I do not know if this radio has fet components that could be damaged by static electricity but to be on the safe side I used a pencil soldering iron that was grounded to the frame to remove the legs and battery from the circuit board. Note the polarity of the battery before removal. The little standoff legs are spot welded to the battery. They may be either gently peeled off with small pliers or you may use a dremel tool with the cutting wheel to grind out the welds to the battery along the long axis of the legs. This last method does not deform the legs like the first method. Tin the insides of the legs where they were welded to the battery. Prepare the new CR 2032 lithium battery by sanding or scraping the surface where the legs will be reattached, then tin it also. With rosin core solder reattach the legs to the new battery. Try to avoid heating the battery more than necessary to get a good solder joint.The top side when completed should be the + side. Note the circuit board has the location for the + lead. Re-solder to board from the component side of the board. Reattach the front panel to the main frame with the ribbon cables on the correct side of the board. Carefully plug the ribbon cables back in, taking care they are fully seated in their sockets. Replace the bottom panel. Plug the speaker plug back into its socket, again grasping the socket gently with pliers to prevent loosening from board. Replace all screws and you should now be able to unplug the radio without lose of memory. I did leave the 13.6 volt dc supply connected the the radio during service as I was not sure if the total loss of memory voltage would damage the internal scanning program. Good Luck. Its not as complicated as it sounds if you have the right tools and some electronic experience.

It used to be that you could reset a Uniden scanner by holding down the #2 and #9 buttons while turning on the radio - that MIGHT do a factory reset for you. Let me know.

I have a Uniden Bearcat "BC 855 XLT" scanner. It scans properly, the antenna is good and the solder connection is good. Yet is will not recieve a signal even the weather. What part needs to be replaced?


There's no telling without completely troubleshooting the unit, and that would likely cost you more than the unit is worth. Used BC855XLT scanners are selling for between $15 and $30 on eBay . . . .
