Code:
Below is a snippet of how it was done on the i760 from KINetics in the i760 forum:
In case you wanted to change to 13k Vocoder:
1. Dial **772
2. Enter the Service Code 000000 (six 0's) and tap OK
3. Push the directional pad down until you see a screen that says:
SVC Mode NAM1
End of BASIC NAM
EXIT
4. Push the directional pad right so that "Exit" bacomes "More"
5. Press the action button (middle of directional pad) to enter the additional settings menu.
6. Press down 1 time to get to the screen that says:
SVC Mode NAM1
Orig. SVC OPT
EVRC
7. The default is set to EVRC. To change to 13k Vocoder press right on the d-pad once.
8. Then press the action button once to save the change.
9. Finally, press the left soft key "Exit" to exit the service menu.
