PROGRAMMING CHECK-FEATURES

PROGRAMMING CHECK - BY PROBLEMS

1. Related to NOT BEING ABLE TO PLACE OR RECEIVE CALL

(1) Check E.S.N. given to system provider (place portable in test mode: press # + 38 + # and use "*" to scroll). This ESN also can be seen on the back of the portable when the battery is removed.
(2) Phone must be programmed in portable mode. If the phone is programmed in mobile mode, the phone will not be able to place calls.
(3) Check NAM programming in portable mode. Check programming parameters as provided by programming guide and system provider(s). Check for proper two phone number programming if applicable. Note that the NAM programming in mobile mode is only used as a method to program the lock and security codes in mobile mode.
(4) Check Selectable System Scan for improper setting. Setting to SCAN A, SCAN B, Home or ROAM can cause "No Service" or "ROAM" conditions. Remember portable and mobile modes each have separate Selectable System Scans.
(5) Check service level, for call restrictions. (Set to service level 4 for full use)

Service level - Command Module - Voice Recognition
1 - only locations 1, 2, 3 - access denied
2 - fully functional - fully functional
3 - disabled - access denied
4 - fully functional - fully functional
5 - only allows use with 7 digit or less numbers - only allows use with numbers 7 digits or less
6 - fully functional - fully functional

(6) If 2 phone number operation has been programmed (Step 10, 2nd phone number. bit 1 = on, 0= off), ensure currently active number is correct and registered for service (Rcl # to check).

2. Related to NOT BEING ABLE TO UNLOCK PHONE
(1) The phone in portable and mobile modes has separate unlock and security codes. They are not downloaded upon power-up. Check unlock codes in both portable and mobile modes. Attempt to unlock phone with unlock code corresponding to its mode.
