5.5. Floodlight and aiming options
The floodlight and aiming options affect the light source that illuminates the area of
the bar code symbol.
The floodlight illuminates the full area during image capturing. When the scannable
area consists of a highly reflecting surface the floodlight might need to be disabled to
prevent over-exposure.
If an aiming light is available, the bar code reader can generate an aiming pattern to
help the user to target at the bar code symbol. The aiming pattern will only be visible
between two image captures. The aiming pattern will be off when the floodlight is on.
Disable floodlight:
The option ‘disable floodlight’ does not illuminate the area of the bar code symbol
during image capturing.
Alternating floodlight:
The option ‘alternating floodlight’ switches by turn between enabled and disabled
floodlight.
Prevent specular reflection
Only when specular reflection of LED illumination occurs, the reading is performed
with illumination turned off.
SET
Disable floodlight D3A
Enable floodlight D39
Alternating floodlight D3B

5.6. Prevention of flicker
When there is not target to be read, flicker occurs because of the LED illumination,
and this flicker can be prevented with setting. However, by enabling the setting, codes
on LCD screen will be difficult to be read.
