Error Messages
If The Non-
Recoverable
Firmware Error
Occurs at Power-up
If the Test Set displays this error when first powered up, disabling Test Set opera-
tion, it could be related to the
Autostart
field on the main TESTS screen, or a
POWERON Save/Recall register. This field causes the Test Set to automatically
run the last program loaded in memory when the Test Set is powered up. If the pro-
gram is corrupted, the Test Set will automatically “lock up”.
The only way to recover from this condition is to clear the Test Set’s operating RAM. This
will clear any IBASIC program, Save/Recall registers, and RAM disks that have been
saved, as well as three calibration factors. The calibration factors are easily re-entered; the
IBASIC programs, Save/Recall registers, and RAM disks must be re-loaded or re-initial-
ized after clearing memory.
To Clear the Test Set’s RAM:
1. Turn the Test Set off.
2. Hold the PRESET and HZ/uV buttons down.
3. Turn the power on (with the buttons still held down) and wait until the CDMA CALL
CONTROL screen is displayed.
Re-enter the Calibration Factors Erased when RAM is Cleared
Use this procedure to re-enter the three calibration factors that were erased when RAM is
cleared. Use the ANLG SCRNS keys (to the left of the cursor control knob) to access the
required screens.
1. Access the RF GENERATOR screen and select the
DC FM Zero
field (under
FM
Coupling
).
2. Disconnect any cables to the ANT IN or RF IN/OUT connectors.
3. Access the TX TEST screen and select
Zero
under the
TX Pwr Zero
field.
4. Access the AF ANALYZER screen and select
Zero
under the
DC Current
field.
