Reset to factory defaults with either Factory Defaults, ESC+ON, or MASTER RESET,
ON. Caution: Use of MASTER RESET, ON, will erase all user saved setups
and measurement traces and return the unit to a fully Factory Default condition. If the error
persists, contact your Anritsu Service Center.

Fan Failure
The system has determined that the fan should be running due to the internal temperature of
the unit, but cannot detect that the fan is actually running.
It is important to keep the fan inlet and exhaust ports clear of obstructions. The cooling fan
will vary the speed in relation to the internal temperature of the instrument. The fan will
turn on at low speed when the internal temperature of the instrument reaches 44
º
C, and will
increase the fan speed to maximum at 54
º
C. As the internal temperature of the instrument
decreases, the fan will reduce speed until the temperature reaches 39
º
C, at which point the
fan will turn off.
