Character Activation Timeout
You can set a timeout for the length of time the aimer remains on and attempting 
to decode barcodes when using Character Activation Mode. Set the length (in 
milliseconds) for a timeout by scanning the following barcode, then setting the 
timeout (from 1-65535 milliseconds) by scanning digits from the Programming 
Chart, then scanning Save. Default = 5000 ms.
Character Deactivation Mode
If you have sent a character from the host to trigger the scanner to begin scanning, 
you can also send a deactivation character to stop scanning. Scan the following On 
barcode to use character deactivation, then use Deactivation Character to select 
the character you will send from the host to terminate scanning. Default = Off.
Deactivation Character
This sets the character used to terminate scanning when using Character 
Deactivation Mode. On the ASCII Conversion Chart (Code Page 1252), find the hex 
value that represents the character you want to use to terminate scanning. Scan 
the following barcode, then use the Programming Chart to read the alphanumeric 
combination that represents that ASCII character. Scan Save to finish.
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.
