the ls 5700/ls 5800 does not have an on/offswitch. as soon as you plug it in, it's ready to scan.
indicator lights
notice the red and green indicator lights inside the scan window. they provide you with information about the scanner's operation. here's what you can expect to see:
1 green light on, red light off- the scanner is on, waiting to decode a symbol.
2 green light off briefly - a bar code has been successfully decoded. you will also hear a beep from the scanner to confirm this.
3 green light on, red light on - the scanner is asleep. see rest/sleep mode, on page 8.
4 anything else - including steady red light, blinking red light, or blinking green light. the scanner is not operating normally. contact the technical person in charge of scanning at your location, or call the symbol support center at the telephone number on page 8.
the ls 5700 has a push button near the top right corner. this push button is to both adjust the volume and tone of the beeper, and to wake the scanner from its rest or sleep mode.
when the scanner is operating, depress this button to adjust the volume/tone. hold down the button until the desired sound is obtained. there are five distinct volume/tone combinations. each combination beeps two times before cycling to the next sound.
if the scanner is in a rest or sleep mode, depressing this push button briefly awakens the scanner.

removing the connector cover allows access to the scanner's connectors.

generally, the technical person in charge of scanning customizes the scanner for your particular application using programming bar codes found in the ls 5700/ls 5800 product reference guide. if you are programming the scanner yourself, consult the product reference guide for moreinformation.
scanning a bar code
the dotted areas below represent the active scan area.

scanning a bar code
for the best scanning performance, the counter top or surface area covered by the active scan area should be free of any de- signs (e.g. stripes or patterns). ideally, that area should be a light solid color. to scan a bar code, move an item through the active scan area in the direction of the arrows, with the bar code label facing the scan window. the scanner beeps when a bar code has been decoded successfully.
