Test Scanning
1.
Ensure all connections are secure.
2.
Aim the scanner at a barcode within range. Assuming the scanner is in
trigger mode (default), press the trigger.
3.
On successful decode, the scanner beeps and the LED flashes green.
Tip
1. Do not hold the scanner directly over a barcode. At 90˚, scanning light can bounce directly back
into the scanner from the barcode area as specular reflection, creating a "dead zone" where
decoding is, at best, difficult. Instead of a 90° head-on approach, tilt the scanner up to 65° forward
or backward to achieve a successful decode. Practice a few times to find what range of angles
works best.
Maintenance
Cleaning the scan window is the only maintenance required. A dirty window may
affect scanning accuracy.
Never use any abrasive material or solvents on the window. Do not spray water
or other cleaning liquids directly onto the window.
Remove dirt by wiping gently with a damp cloth or tissue moistened with water
and/or ammonia.
