CTIVATION
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.
