Product Reference Guide

This feature specifies the amount of time that the Good Read LED remains on following a good 
read. The good read LED on time can be set within a range of 10 milliseconds to 2,550 
milliseconds (0.001 to 2.55 seconds) in 10ms increments.

Follow these instructions to set this feature:

1. Determine the desired setting in milliseconds. A setting of 0 means that the good read 

LED stays on until the next time the trigger is pulled.

2. Divide the desired setting by 10 (setting is in 10ms increments). Pad the result with lead-

ing zeroes to yield three digits. For example: 0 = 000, 5 = 000, 20 = 020, etc.

3. Scan the ENTER/EXIT PROGRAMMING MODE barcode to enter Programming 

Mode.

4. Scan the barcode: SELECT GOOD READ LED DURATION SETTING.

5. Scan the appropriate three digits from the keypad in 

Appendix E, Keypad

 representing the 

duration which was determined in the steps above. You will hear a two-beep indication 
after the last character.

6. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming 

Mode.

This completes the procedure. See Table

3

 for some examples of how to set this feature.
