Honeywell 3820 Barcode Reader User Manual


 
3 - 5
If there are no trigger pulls during the “image scanner power time-out timer”
interval, the image scanner goes into power down mode. Whenever the trigger
is enabled, the “image scanner power time-out timer” is reset. If the image
scanner is placed in the 2020 cradle and the battery is in the process of being
charged, the image scanner will not go into power down mode.
Note: When the image scanner is in power down mode, pull the trigger to power
the unit back up. There will be a set of power up beeps and a delay of up
to a few seconds for the radio to join. The image scanner will then be
ready to use.
Automatic Trigger
The image scanner scans continuously at full power with illumination fully on.
Presentation Mode
The LEDs are off until a bar code is presented to the image scanner. Then the
LEDs turn on automatically to read the code. Presentation Mode uses ambient
light to detect the bar codes. If the light level in the room is not high enough,
Presentation Mode will not work properly.
