5.7 Self-Test Procedures
An i 860 unit allows you to conduct automatic self tests to ensure that it is working properly. Self-
test procedures include gathering information from the unit’s displays and testing the functionality
of basic components. These procedures usually do not require test equipment other than a reference
SIM card.
The following self-tests can be performed on an i 860 unit:
•
Passcode
•
Programming Menu Settings
•
Call Performance
5.7.1 Passcode Test
Use this test to determine the passcode for the unit.
The passcode test time is approximately 5 minutes:
1. Power on the unit.
2. If the display reads Unit Locked Enter Code , enter 0000 or the 4-digit code provided by the
customer. (If the customer has changed the passcode but does not remember the new code, read
the codeplug to determine the passcode.)
3. If the passcode unlocks the unit, from the Main Menu, select Settings > Security > Phone
Lock, and press
A
under Off .
If the unit does not unlock, repeat the test. If the problem persists, send the unit to the field level
of service.
NOTE: If applicable, ensure that the unit’s codeplug file is copied and retained for future use.
