LED Power Level
This selection allows you to adjust LED and aimer brightness.
Off
is used when
no illumination is needed.
Low
is used if low illumination is sufficient.
High
(the
default) is the brightest setting.
If you have an aimer delay programmed (see
Aimer Delay
on page 4-11), the
aimer will be at 100% power during the delay, regardless of the LED Power
Level.
Note: If you scan the
Off
barcode, both the aimer and illumination lights turn off,
making it impossible to scan barcodes in low light. To turn the LED Power
Level back on, move to a brightly lit area and scan either the
Low
or the
High
barcode below.
Illumination Lights
If you want the illumination lights on while reading a barcode, scan the
Lights On
barcode, below. However, if you want to turn just the lights off, scan the
Lights
Off
barcode.
Note: This setting does not affect the aimer light. The aiming light can be set
using
Aimer Mode
(page 4-11).
