ACK NAK Retry Count
This feature specifies the number of times the scanner retries a label transmis-
sion due to a retry condition. The selectable range is from 1 to 254 retries. A
selection of 0 disables the count, and a selection of 255 specifies unlimited
retries.
To set this feature:
1. Determine the desired setting.
2. Pad the number with leading zeroes to yield three digits. For example: 0 =
000, 5 = 005, 20 = 020, etc.
3. Go to page 31 and scan the ENTER/EXIT PROGRAMMING MODE bar code to
enter Programming Mode.
4. Scan the bar code: SELECT ACK NAK RETRY COUNT SETTING.
5. Scan the appropriate three digits from the keypad in
Appendix D, Keypad ,
that represent the number 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 the table below for examples of how to set
this feature.
Table 6. ACK NAK Retry Count Setting Examples
NOTE
If you make a mistake before the last character, scan the CANCEL bar
code to abort and not save the entry string. You can then start again at
the beginning.
