BASIC LEVEL TEST MODES AND PROCEDURES
To complete basic testing of an i580 unit, you must enter a test mode to retrieve data from the unit,
and perform the technician tests in the correct sequence with the appropriate equipment.
Test procedures are listed in the order in which they should be implemented. Each test contains a
description of what it does, the approximate time needed to perform it, and the type of equipment
required (if any).
NOTE: The unit must be powered up and registered before performing most tests.
6.1 Test Modes
Some tests require that a certain mode be entered to conduct the test and/or retrieve data from the
unit. The following test modes are used with this unit:
• Debug/Trace Mode
• Test Mode
NOTE: Do not enter these modes until the unit has been powered up and the power-up sequence
has been completed.
6.1.1 Entering Debug Mode
Use this procedure to access the Debug Mode.
To enter Debug/Trace Mode:
1. Power up the unit. Wait until registration is complete before continuing.
NOTE: Steps 2 through 5 must be performed quickly with no more than one second between
each key press: (#, *, M, >)
2. Press #.
3. Press *.
4. Press Menu.
5. Press the right Scroll key. You now are in Debug Mode.
If you press the option key under Trace while in Debug Mode, you can enter Trace Mode. To
exit Trace Mode, re-enter Debug Mode, press the option key under Trace again, and then press
the option key under Exit.
In Trace Mode, the unit switches every five seconds between Debug Mode and normal
operation to allow you to monitor and sample a variety of signals and signal characteristics,
particularly in the SQE/Carrier and multi-data displays.
