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 41 and scan the ENTER/EXIT PROGRAMMING MODE barcode to enter Pro-
gramming Mode.
4 Scan the barcode: 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 barcode to exit Programming Mode.
This completes the procedure. See Table ACK NAK Retry Count Setting Examples for some 
examples of how to set this feature.

NOTE
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 beginning.
