Power ON with Trigger Key
If the Trigger key has been set to “Enable turning on the power with Trigger key”, the power can
be turned on (while the power was being turned off) when it is pressed. This function allows the
user to achieve multiple operations with only one action, turn on the power → press the Trigger
key → scan a bar code. This feature is a perfect idea when the user wishes to resume scanning
after the power has been turned off. The default is “Disable turning on the power with Trigger
key”.
Setting Trigger Key
Enter key, 4-way cursor key, side trigger key, grip trigger key (option) and center trigger key on
the front of the terminal can be set as the Trigger key. The default is only both left and right side
keys are set as the Trigger key.
Noise Filter
If the background of a bar code is white color, a noise tends to be generated easily during
scanning causing the error rate to increase. To reduce such the noise, the noise filter function is
available with the terminal. Two methods are available to set the function operable.

Filter Description Merit Demerit
A software process removes noise. In
determining the blank at the leading edge of the
barcode, if there is a bar width smaller than a
certain value, it will be bonded to the fore and
aft data, the noise eliminated and the
determination made. Also, the time from scan
start to “enable” of software filter can be set.
Software
noise filter
Setting range: 1 to 8 seconds, Default : 3
seconds
Effective when
scanning leading
edge blank of bar
code using laser
module noted for
easily picking up
noise.
If initial bar is
extremely thin, it
will be determined
as noise and
eliminated, which
may mean that the
bar code cannot be
scanned.
ASIC noise
filter
Removes noise using the ASIC process. If there
is a bar width smaller than a certain value, it
will be bonded to the fore and aft data, and the
noise eliminated. This is normally effective in
preventing DMA overrun.

Notes:
• Only the ASIC noise filter has been set enabled as default.
• The software noise filter is not required by the DT-X7 series.
