Decoded (Internal) Advanced Options
Dot Time (msec)
The value selected for Dot Time (msec) determines (in milliseconds) how long the targeting
dot remains on before the scanner switches to a normal scan sweep. When you double-tap
on this parameter, a dialog box is displayed in which you can enter a value of 0 msec, 200
msec or 400 msec. A value of 0 (zero) disables the target dot.
Aim Duration
This parameter determines the total time the aiming pattern appears before the scanner laser
begins sweeping. When you double-tap on this parameter, a dialog box is displayed in which
you can enter a value from 0 to 30 (0 to 3 sec.). A value of 0 (zero) disables the aiming-dot.
Laser On Time
The value assigned to this parameter determines how long the laser will remain on when the
scan button or trigger is pressed.
Double-tapping on this parameter displays a dialog box in which you can enter a value
between 5 and 99, each number representing 0.1 seconds.
C.2.2 Decoded (Internal) Advanced Options
Continuous Scan Mode
Setting this parameter to on keeps the laser on and continuously decoding as long as the
scanner button is pressed and held down.
Minimum Cancel Time
The value assigned to this parameter determines the time delay before the scanner is turned
off, once the scanner trigger or button is released. This gives the scanner a minimum amount
of time to complete its current decode before the scan is cancelled when you quickly trigger
on/off.
Power Mode
This parameter is a power-saving option. Tapping on it displays a screen listing two power
mode options: Continuous Power and Low Power.
In Continuous Power mode, the scanner is always on, waiting for a trigger pull or a serial
communication.
In Low Power mode, the scanner is in a standby state, drawing minimal power until a trigger
pull or serial communication wakes it. Keep in mind that while this option is more suitable
