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. Default = Lights On.
Note: This setting does not affect the aimer light. The aiming light can be set using Aimer 
Mode (page 25).
Aimer Delay
The aimer delay allows a delay time for the operator to aim the scanner before the 
picture is taken. Use these codes to set the time between when the trigger is pulled 
and when the picture is taken. During the delay time, the aiming light will appear, 
but the LEDs won’t turn on until the delay time is over. Default = Off.
