The scanner is not connected to the cradle. Scan the pairing barcode on top of the cradle.

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.

4 beep error when scanning barcode


The four beep error is a communications error. Usually it indicates the scanne is not configured properly. If the scanner is connecting with the CBA-K01-S07PAR cable and you are using a PS/2 keyboard you should have scanned the IBM PC/AT barcode from Adobe page 56 of 342 of the LS2208 Product Reference Guide.

If you do not have a PS/2 keyboard attached and are using a USB to PS/2 adapter you should scan the IBM AT Notebook from that same page. If the scanner does not start working immediately you may have to reboot your system. If the scanner still does not work the CBA-U01-S07ZAR USB cable might be a better choice.

If you are not connecting with either of these cables and are still getting the four beep error a call to the Motorola support center may be in order. Their phone number is 800-653-5350.

Four beeps wont turn on, Dell 4700


The four beeps usually indicate a memory problem and it won't pass it's Power On Self Test. Try reseating the memory sticks, or, if you have two of them, take one out and try to start the machine and then swap them.
If this doesn't solve the problem, you most likely have a bad motherboard.

Symbol LS 4000i scanner issues


Hello, it looks like the scanner lost the settings. As power is there, so connection is ok. The several (four) beeps after reading the barcode means communication error.
Please try to find the original sheet with configuration barcodes or download it from support.symbol.com website, you would need to scan the barcode for IBM PC/AT & IBM Compatibles from Keyboard Wedge Chapter.
