Aiming the Barcode Scanner
Aim the scanner away from you, direct it at the barcode and press the trigger to scan.
The Scan On LED (or equivalent) turns red to indicate the scanner is on.
Adjust the aim so that the thin, red laser beam covers the entire length of the barcode.
Some scanners use a laser aiming beam which then spreads into a wide beam when the scanner’s
Aiming Beam Timer expires. Place the aiming beam in the center of the barcode and hold the
scanner steady until the beam spreads and the barcode is decoded. Beeps may be heard as the
barcode is decoded. Refer to the barcode scanner user’s guide for information on the Aiming
Beam Timer and beep sequences, and the TE reference guide for host generated beep sequences.
