Reading Parameters
Illumination Mode
This feature allows you to select the illumination mode for the reader. The illumination mode
can be used to:
• increase the overall diode life
• reduce power consumption
• turn off the illuminator for safety purposes
Selections:
• Disabled: the illuminator is always off
• Enabled: the illuminator is always on
• Triggered: the illuminator is turned on when the r
e
ading phase starts. The illuminator is
turned off as soon as the code(s) are read or when the reading phase ends.
The triggered selection is ignored for Automatic and Test Operating
Modes.
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 100 milliseconds to 25,500
milliseconds (0.1 to 25.5 seconds) milliseconds 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
z
eroes to yield three digits. For example: 0 = 000, 5 = 005, 20 = 020, etc.
3. Go to page 69 and 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 D, Keypad representing
the duration which was determined in the steps above. You will hear a two-beep indica-
tion after the last character.
If you make a mistake before the last character, scan the CANCEL barcode to
abort and not save the entry string. You can then start again at the begin
-
ning.
6. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming
Mode.
This completes the procedure. See Table 33 for some examples of how to set this feature.
