3 - 5
Manual Trigger Mode
When in manual trigger mode, the scanner scans until a bar code is read, or until the trigger is released. Default = Manual Trig-
ger-Normal.
LED Illumination - Manual Trigger
If you wish to set the illumination LED brightness, scan one of the bar codes below. This sets the LED illumination for the
scanner when the trigger is pressed.
Default = High.
Note: The LEDs are like a flash on a camera. The lower the ambient light in the room, the brighter the LEDs need to be so
the scanner can “see” the bar codes.
Serial Trigger Mode
You can activate the scanner either by pressing the trigger, or using a serial trigger command (see Trigger Commands on page
8-3). When in serial mode, the scanner scans until a bar code has been read or until the deactivate command is sent. The
scanner can also be set to turn itself off after a specified time has elapsed (see
Read Time-Out , which follows).
Read Time-Out
Use this selection to set a time-out (in milliseconds) of the scanner’s trigger when using serial commands to trigger the
scanner. Once the scanner has timed out, you can activate the scanner either by pressing the trigger or using a serial trig-
ger command. After scanning the
Read Time-Out bar code, set the time-out duration (from 0-300,000 milliseconds) by
scanning digits on the Programming Chart inside the back cover, then scanning Save . Default = 30,000 ms.
Presentation Mode
Presentation Mode uses ambient light to detect bar codes. The LED dims until a bar code is presented to the scanner, then the
LED brightens to read the code. If the light level in the room is not high enough, Presentation Mode may not work properly.
