if there is no scanning activity for a specified period of time, the scanner enters a rest or reduced power mode. the default is 30 minutes. you can change this period of time by scanning the appropriate bar code in the product reference guide. this mode saves power and extends the life of the scanner. the ls 5700/ls 5800 automatically awakens as soon as you pass a bar coded item past the scan window.

    the ls 5700 also has a programmable shut-down sleep option that turns off the laser and the motor. the scanner can be awakened from this mode or the rest mode by momentarily depressing the push button on the top right corner. when you press this button, the scanner emits two beeps. the volume and tone settings remain unchanged.
