Question about Symbol LS4278 Cordless Barcode Scanner - P/N LS4278-TRWM0100ZWR Barcode Scanner

Open Question

Backlight turns red repeatedly ...

Which I assume means that the unit isn't taking a charge. All four of our scanners are doing this which makes me think it might be a driver thing. Any thoughts on this?

Hi, I need to know how to program the DB Power barcode scanner model # BCE0008

Unfortunately, this is all I can find for instructions.
Operation Instructions:
1. Connect the USB receiver to the host (e.g.: PC)
2. Pull the trigger to start the scanner. It works on two beeps.
Notes: 1. The charging port on the scanner is for battery charging only. Do not connect it to data cables.
2. The LED light at the scanner bottom is on and red under charging and off when charging is finished.
3. During working, the scanner will auto shut down in case of not in use for 20 second.
4. The receiver was paired to the reader at factory. Do not pair again unless necessary. When self pairing is needed, please first read the code CHANNEL SETTING. (Before setting, please reset the receiver until the light turns long green. Reset it to the light off when setting is finished.

My canner ls4278 is making a sound and turnin red when i scan

It could be the scanner is not paired to the cradle. The scanner will be once for the barcode and then four times for the communication error. Make sure the cradle has power; it will pull power from a USB port. Scan the pairing barcode on top of the cradle. The scanner will give a high low high low beep and then shortly after give a short low short high beep indicating the radios have paired. If the scanner still beeps four times after doing this, the host type may not be set. If connecting USB scan HID Keyboard from the LS4278 Product Reference Guide.

My screen has gone very dark - what do I need to do to brighten the screen

You don't give any information about your computer, and that makes it hard to give a precise answer. But if you have a laptop, or you're having this trouble with an LCD monitor on a desktop computer, the display backlight may have quit working. Without the backlight you can only very dimly see the display. The usual reason is that the inverter board (in a laptop) or power supply (desktop monitor) isn't working.

Laptop inverter boards are pretty simple to replace, and you can find them for most brands and models now at reasonable cost. Check eBay where there are many sellers. Once you have the replacement, you just need to remove the front bezel of the display, which usually means taking out screws at the corners and releasing snap tabs around the edges. The inverter board mounts below the display panel and there are two cables connected. Unplug the cables, remove the old inverter, put the new one in and reconnect the cables and you're done. The brightness should be back to normal. (It's also possible but less common for the backlight lamp in the LCD panel itself to be bad. While it is possible to replace the lamp it is very difficult to do. It's usually simpler and safer to replace the whole display panel, although they can be expensive.)

In a desktop monitor, bad capacitors in the power supply often cause the backlight to go out. Many sites show what bad capacitors look like and describe how to remove and replace bad ones. It's a more difficult repair than the laptop inverter replacement, involving soldering on the circuit board, but it's still something you might be able to yourself.

Good luck, and thanks for using FIxya!

When I try to turn on the computer it beeps repeatedly and won't turn on. Its a SR5520AN

Beeping means a loose card inside your pc, so open it up and make sure than no cards like the graphics, sound or memory are not loose and also blow out any dust you see and this can cause the pc not to tuen on aswell.
Hope this helps.

Hi can you tell me is it dificult to remove and replace the icc unit in a BA falcon ute. Is just a case of removing the four screws holding it in then pulling the whole panel out

Unfortunately NO. It needs a specialists to remove and replace that component. If you do it yourself you might ruin other components there without your knowledge. Take it to a specialist and have him do the job for you. Spending $5-$15 won't hurt to make this thing work.

I have a symbol 9090 scanner and when the batteris goes dead, it keeps loosing all the settings. I have exported the profile like I was told to do, but it still looses the settings. I am at a loss as to...

Hello rcatron. I think I can help hammer-out your issue. The MC9090 has a backup battery similar to a BIOS battery on a PC motherboard. What this does is holds a constant charge so that the unit's settings are always active and ready to be recalled when it starts up. Generally speaking: if the settings aren't coming back after you reset the unit, it would mean that the backup battery has lost it's charge and with that the ability to hold the configuration (cache/flash) data. However, since all of your units are doing this (correct?) I highly doubt that all of their backup batteries have gone belly-up simultaneously. There a couple causes that immediately come to mind.
  1. The backup battery draws it's charge from the main battery or power source just like a BIOS on a PC draws it's power from the power-supply even when the computer is "off". So, if you take the batteries out (maybe to charge them?) overnight or for extended periods of time, this would be your problem. If so, simply leave the batteries in the units or place them in the cradle whilst not using them for more than 5 hours or so.
  2. When you say you are losing all the settings, are you referring to the general operating system settings (wireless network, backlight, and things like that)? Or are you talking about a custom application that you use for your inventory control? If it's the latter, then I recommend you make a call to your software provider and ensure that the settings are being properly saved and more importantly: in the right place. This could be an issue.
If neither of these apply, then please feel free to send me a message or an email and I will be happy to help you troubleshoot further. I hope this helps. Good luck!
