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.

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.
This 4 beeps also stays for communication error. Please check the connection to the cradle and also the connection between the cradle and PC.
You can start by pairing the scanner with cradle with the Pairing barcode, then defaulting the scanner to the standard settings - use the barcode "Set All Defaults" from the manual. Then select the right host type USB, RS232 or another.
After this procedure should the scanner work.
Check metroselect single line configuration guide page no. 2
1) Scan Enter/Exit configuration mode it gives 3 beeps
2)Scan recall defaults it gives single beep
3)Scan Enter /exit configuration mode it gives 3 beeps
Now scanner is set to default setting
Print Adobe pages 128 and 129 of 302 of the M2000 Series Product Reference Guide and scan the "Scan Options" "Data Suffix" and "Enter" barcodes. The scanner will give two beeps after the first barcode, two beeps after the second and a warble after the third programming (Enter) barcode.
Hi, I would be happy to assist you in resetting your LS4278, but it would be helpful to know how you are connected. The Set Defaults barcode will reset all of the scanner settings, but it will also cause you to lose the "pair" (communications) between the scanner and cradle. If you try scanning a barcode at this point you will receive a single beep followed by four error beeps. This just means the scanner is not talking to the cradle. Scan the barcode on top of the cradle. The scanner should give a high low high low series of beeps followed by a short low short high. The short low short high indicates the scanner is talking to the cradle again and you are ready to scan.
If you are connected through the USB port and scan a barcode and get one beep, but do not see data on your host try unplugging the black power supply cable from the cradle. Try scanning your barcode again and it should show up on the host.
The default setting for this scanner is EAN13 enabled. This means that all 12 character barcodes will be changed to 13 characters by adding a zero in front.
How to Disable:
Open the manual that came with the scanner (it's available to download on the Cipherlab web page if you don't have it).
Find the UPCA Parameters barcodes (currently page 29). The next heading down is Convert to EAN13. You will see the disable and enable barcodes.
1) Scan Enter Setup Barcode (on practically every page of the manual at the bottom). The scanner will beep 6 times.
2) Scan the Convert to EAN13 Disable barcode. The scanner will beep once.
3) Scan the Update barcode at the bottom of the same page.
Your scanner should now read both 12 and 13 character barcodes correctly.
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.
