5.6 Troubleshooting
Troubleshooting can help identify the problem and determine the next action to take (continue
testing, replace parts, or send unit to the Radio Support Center). Refer to the iDEN Customer Care
Troubleshooting Guide for information on how to perform common troubleshooting procedures.
5.7 Self-Test Procedures
An i850/i760 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 i850/i760 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 the Option key 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.
