ACK NAK Retry Count
This feature specifies the number of times the reader retries a label transmission 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 36 and 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.
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.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit Programming Mode.
This completes the procedure. See Table 29 for some examples of how to set this feature.
