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. Scan the ENTER/EXIT PROGRAMMING MODE barcode to enter Programming
Mode.
4. Scan the barcode: SELECT ACK NAK RETRY COUNT SETTING.
5. Scan the appropriate three digits from the keypad in Appendix E, Keypad , that repre-
sent the number which was determined in the steps above. You will hear a two-beep indi-
cation after the last character.
6. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming
Mode.
This completes the procedure. See
Table 11
for some examples of how to set this feature.
Table 11. ACK NAK Retry Count Setting Examples
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.
