On/Off - Honeywell IntuVue RDR-4000 Pilot's Manual

ON/OFF

The radar may be turned completely off by selecting OFF with the
System Control Switch, which is located in the top center of the control
panel. When this switch is in the OFF position, no weather radar
information is available, and no predictive windshear detection will
occur. This switch should always be set to ON (System 1 or System 2
selected) whenever it is safe to operate the radar. This will ensure that
the radar is always scanning while in flight so that the most current
weather information is instantly available in the 3D memory.
The Radar is OFF (Not Transmitting) when:
 The System Control Switch on the Radar control panel is set to OFF
 Or the System Control Switch on the Radar control panel is set to
either System 1 or System 2, and
o The aircraft is on the ground and the PWS Qualifiers are not
satisfied (See AUTOMATIC WINDSHEAR ACTIVATION on pg 18)
o And the Display Selection Knobs for both the CAPT and F/O are
set to OFF
