2D Reread Delay
Sometimes 2D bar codes can take longer to read than other bar codes. If you wish 
to set a separate Reread Delay for 2D bar codes, scan one of the programming 
codes that follows. 2D Reread Delay Off indicates that the time set for Reread 
Delay is used for both 1D and 2D bar codes. Default = 2D Reread Delay Off.
Illumination Lights
If you want the illumination lights on while reading a bar code, scan the Lights On 
bar code, below. However, if you want to turn just the lights off, scan the Lights Off 
bar code. Default = Lights On.
Note: This setting does not affect the aimer light. The aiming light can be set using Aimer 
Mode (page 45).
