New PRO-433 / Backlight Stopped Working...

[ErnieB]

I have a new RadioShack PRO-433 that I received for Christmas. However, I didn't get a chance to set it up until this past week. Last night, while entering/moving some freq.'s, the backlight just stopped working - as if I hit a shut-off switch! The manual has nothing to say about the backlight (as usual with this manual!) and I've done everything that I know to do to get it to come back on. I thought that maybe I'd done something to turn it off while using the keypad.

I am hoping that someone might be able to tell me if I DID push a wrong button, or, if perhaps the bulb just burned out - which shouldn't happen on a new scanner! I would think that there should be a way to adjust and/or turn the light on or off... Any help will be GREATLY appreciated.

DM/M-LOCK
Lets you set the display brightness, or locks the
memory. To set the brightness of the display
backlight select BRIGHT, DIMMER or OFF.

Jerri,

Thank you so very much! I now understand how I turned it off!

I guess I jumped too quick regarding the fix for my backlight problem... I went to the menu to find where to turn the backlight "ON" but I didn't find anything regarding said light! I have noticed that some of the "words" in the menu box don't seem to appear on screen exactly as they are shown in the manual. Additionally, all I can find are menu items related to the "Signal Stalker I" settings. I also tried using the M-Lock/DM button with no results there either.

I apologize that I let my enthusiasm over-load my skill level, but could someone please provide me some further info as to what I'm doing wrong? FWIW, I did re-set what looked somewhat like "S-S Lit" but changing that from "off" to "on" didn't do anything.

Thanks (again),
Ernie

If the DM/M-LOCK key didn't work I think it's time to take a trip to Radio Shack with the scanner and get a replacement. That button is the only control on that scanner for backlight control.

Thanks once again. I tried pushing that DM/M-LOCK key and the only response I got was turning the M-LOCK on and off if I kept it pushed in for too long. I guess I'll take back into RadioShack and take advantage of their "World-Class" warranty service!

... The manual has nothing to say about the backlight (as usual with this manual!) ...

The manual mentions the light on pages 13 & 37, but it does not explain how it works.
When you push the DM button it steps through BRIGHT, DIM and OFF.

It looks as if there are 6 bulbs, 3 on each side, so it is likely to be just a loose connection. If you are comfortable in opening the case, you can check the wire connections. It might save you a trip back to RS.

Dick,

Thanks for that info. It does seem awful strange to me that all the bulbs went out at once. I was looking right at the scanner went the lights went out. As I said in an earlier post, it was as if a switch was flipped - no blink, flutter, brighter, dimmer - nothing. I will give your suggestion a try as soon as get time.

Hello Again Folks,

Well, I took out the screws, as Dick H suggested, looked at everything REALLY, REALLY hard - didn't see anything loose - put it back together - AND THE LIGHTS CAME BACK ON!! I guess it just needed a nasty, mean look at it's insides and decided not to mess with me any further! BTW, the DM switch works as it should now - dimmer, lighter & off.

Thanks to all,
Ernie
