Piper Malibu Meridian PA-46-500TP Airplane Maintenance Manual page 1036

WARNING: AIRBORNE WEATHER RADAR SHOULD BE OPERATED ON THE GROUND ONLY BY
QUALIFIED PERSONNEL.
WARNING: THIS INSTRUMENT GENERATES MICROWAVE RADIATION.
-- DO NOT ALLOW PERSONNEL TO STAND NEAR OR CROSS IN FRONT OF A
TRANSMITTING RADAR ANTENNA.
-- DO NOT ALLOW PERSONNEL TO LOOK INTO A WAVEGUIDE, OR INTO THE OPEN
END OF A COAXIAL CONNECTOR OR LINE CONNECTOR TO A RADAR
TRANSMITTER OUTPUT.
WARNING: DO NOT OPERATE RADAR WHILE AIRCRAFT IS IN A HANGAR OR OTHER
ENCLOSURE UNLESS THE RADAR TRANSMITTER IS NOT OPERATING OR THE
ENERGY IS DIRECTED TOWARD AN ABSORPTION SHIELD WHICH DISSIPATES THE
RADIO FREQUENCY (RF) ENERGY.
A. Removal
(1) Remove screws (13) and remove the radome.
(2) Disconnect ground wires, antenna transceiver connector, and configuration module connector.
(3) Remove screws (4) and remove the antenna transceiver / array assembly.
(4) Remove screws (2) and remove the configuration module.
B. Installation
(1) Position the configuration module and secure with screws (2).
(2) Position the antenna transceiver / array assembly and secure with screws (4).Torque to the
low side of 60-70 in.-lbs.
(3) Connect ground wires, antenna transceiver connector, and configuration module connector.
(4) Position the radome and secure with screws (13).
C. Self-test
NOTE: This procedure does not apply when the Avidyne Entegra EFIS is installed.
The following displays basic system fault information and tests antenna clearance. Use the GAIN,
TILT, and function knobs and the RNG and mode buttons on the IN-182A indicator.
(1) Set the radar function knob to TST.
(2) Turn GAIN knob to minimum.
(3) Set antenna TILT to full up and select a range (RNG) of 240 NM.
(4) At the same time, depress the Wx/WxA and VP mode buttons to display the maintenance
menu. (See Figure 2.)
(5) Press the range up (RNG ^ ) to display the RT CALIBRATION DATA page. (See Figure 3.)
(6) As the RT CALIBRATION DATA page comes up, all fault fields will flash briefly. When the
display stabilizes, the only fault field displayed should be XMITTER. If any other fault fields are
displayed, further investigation is required.
(7) To initiate the antenna clearance test, rotate the GAIN knob to obtain a GAIN POT %2 value of
-26.5 to -28. The antenna will then move to each of its extreme positions to verify that there is
no physical interference and to ensure that all scan motors are working properly.
