ACK NAK Retry Count
This feature specifies the number of times the reader 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. Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Program-
ming 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 Table 9 for some examples of how to set this
feature.
Table 9. 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.
