Good Read LED Duration
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
0.1 to 25.5 seconds in 100ms 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 100 (setting is in 100ms increments). Pad the
result with leading zeroes to yield three digits. For example: 0 = 000, 
5 = 005, 20 = 020, etc.
3. Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Program-
ming Mode.
4. Scan the bar code: SELECT GOOD READ LED DURATION SETTING.
5. Scan the appropriate three digits from the keypad in
Appendix D, 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 bar code to exit Programming
Mode.
This completes the procedure. See Table 18 for some examples of how to set
this feature.
