Digital Scanner Activity Modes
The digital scanner is capable of four modes of activity:
•
Active Mode - The digital scanner uses full illumination for active scanning.
•
Idle Mode - In presentation mode only, the digital scanner’s illumination dims after a programmable time
period. See Time Delay to Presentation Idle Mode on page 4-13 . The digital scanner wakes when it is lifted or
senses motion, upon presentation of a bar code, or upon a trigger pull.
•
Sleep Mode - In presentation mode only, the digital scanner’s illumination shuts off after a programmable
time period after Idle Mode has expired. See Time Delay to Presentation Sleep Mode on page 4-15 . The
digital scanner wakes when it is lifted or senses motion, upon presentation of a bar code (depending on
ambient light conditions), or upon a trigger pull.
•
Low Power Mode - The digital scanner enters a low power consumption mode after Sleep Mode has
expired, in which the LEDs turn off in order to conserve energy and prolong the life of the scanner. See Low
Power Mode . In hand-held mode, this occurs immediately after the programmed Time Delay to Low Power
Mode . In presentation mode, this occurs after idle mode and sleep mode. The digital scanner wakes when it
is lifted, senses a trigger pull, or when the host attempts to communicate.
