N:\mkt\MANUALS\HP8924C\ALR\trouble.fb
Step 1- Run the Power-up Diagnostics
To start troubleshooting:
• Turn on the Test Set to automatically run the power-up diagnostics.
• After power-up, the top line of the Test Set’s display should show copyright
information and the firmware revision code. The second line should display
All self
tests passed
.
• The CDMA CALL CONTROL screen should be displayed. Two conditions cause a
different screen to be displayed on power-up:
r A SAVE/RECALL register named POWERON was saved to automatically power-
up the box in a different state. Press the PRESET key before proceeding; this will
restore the Test Set to the factory power-up condition.
r The
Autostart Test Procedure on Power-Up:
field is set to
On
to
automatically run a loaded program. Press the SHIFT key, then press the CANCEL
key to stop the program. Press the PRESET key to restore the Test Set to the factory
power-up condition.
To turn the autostart function off, press the TESTS key, then select
Execution Cond function (under the
SET UP TEST SET:
heading). The
autostart function is at the bottom of the screen; turn it
Off
.
If
All self tests passed
is displayed, run the Functional Diagnostics to try
to locate the fault.
If the Test Set powers up with an error condition, or if the screen is blank:
