IR SENSOR ACTIVATION An infrared (IR) sensor located behind the scanner window initiates the scanning
process. In short range mode the signal projects approximately 101.61 mm –
177.84 mm (4" – 7") beyond the output window. In long range mode the signal
projects approximately 228.61 mm – 330.21 mm (9" – 13") beyond the output
window. The IR sensor remains active as long as the unit is powered.
When the unit remains dormant for a time, the laser will turn off. In this stage, the
scan engine’s computer is on “standby”. To reactivate the unit, present an object
within the scan field.
The model number on each scan engine includes the scan engine number and
communications protocol.
