Radio Shack PRO-2046 will not retain memory after unpluged for about 24 to 48 hours,, supect memory back up capacitor bad. What is the "C" number on the schematic for this capactior and value of it?

My Radio Shack Scanner Pro-2046 loses it memory after it is unplug-ed for about 24 hours or less. The memory capacitor is probably bad. Where on the PCB is this memory capacitor and it value. I cannot find any "C" numbers for capacitors stamped on the bottom side of the PCB. With the scanner face, facing towards me, up side down on the very far right middle there is a large button style capacitor approx: 1/2 in Dia. and about 1/2 high and there is a L-13 next to it. Is this the memory Capacitor? on towards the back of the unit there is a taller capacitor about 1 inch in height and about 3/8 inch in Dia. next to a transformer and power jack. Up front in the middle there is a 470 uf capacitor "C" number unknown, next to VR-1 and IC-5. I know that the unit is suppose to retain its memory for approximate 14 days after it is unplugged. Would someone tell the the location of the memory capacitor and the value of it PLEASE. n5flb, ham call sign (a ham of 43 years) www.n5flb@yahoo.com

SOURCE: 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.

Program stored frequency memory problem


very possible this one has an internal battery that need to be replaced. I am not talking about your radio battery itself, inside there is a coin size battery like a 2025, 2020, 2032, etc. you can get them at radio shack, walmart, lots of places. take the back off and look inside to see. mine did and replaced it and now it works fine. your model may be different, but it is worth a try. if that is not the answer then the memeory chip is bad or the the capacitor on it has failed

Unplug the tv for about 5 minutes. If it comes back on and plays properly then you are likely to have a bad power supply which has bulged capacitors on it. If you are proficient in soldering and unsoldering you can save buying the entire power supply. The bad capacitors will be domed or bulged on the top. They are cylinder shaped components and good ones are flat on top (usually). You can usually get capacitors at Radio Shack and are the radial type and not axial. Radial is the two pins at the same end.. Do a search with your model number in Ebay or Google or shopjimmy.com to find a power supply should you need one. Be sure to match the picture for picture with your power supply and also match the numbers

The memory on the unit is not retaining the frequencies. Check for a small battery on the circuit board like a button battery you would find on your computer motherboard. Replace the battery and reprogram the unit.

Looses frequencies programmed


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!

My magnavox 37mf321d 37 LCD tv


This is a bad power supply and an easy fix. Their are several electrolytic capacitors on the power supply. If one is bad it will have a bulge on the top. Mine had a bad 2200uF and a bad 1200uF capacitor. About $7 worth of parts at Radio Shack. Radio Shack had the 2200uF but it was axial leads instead of radial. (leads come out of each end instead of one end) but It will still fit. They only had a 1000uf capacitor so I combined that with a 220uF capacitor and wired them in parallel. Make sure you put them in with the correct polarity.

"ALL CHANNELS LOCKED OUT' RADIO SHACK COULDN'T HELP.


If the scanner's display locks up or does not work properly after you connect a power source, you might need to reset or initialize it. If you have problems with the scanner, first try to reset it to retain the memory. Warning: Initializing the scanner will clear all channel memories and reverts it the state it was in right out of the box. To Initialize the scanner, turn off the scanner then turn it back on. Press 0 when the welcome screen appears. 'Please select factory tests. Exit if no key is pressed' will briefly appear. Then quickly press 1. 'Initialization clear all memory Enter to confirm Clear to exit' will briefly appear. Quickly press ENT to initialize. 'Initializing, Please stand by' then appears. Do not turn off the scanner while it is initializing. The display should then show M000 on the top line and Bank 0 CH 00 when finished.
