XPNDR – transponder operates with altitude reporting.
TA ONLY – enables display of traffic advisory TCAS targets.
TA/RA – enables display of traffic advisory and resolution advisory TCAS targets.
Refer to Chapter 15, Warning Systems.
TEST Switch
Push – initiates self–test.
Identification (IDENT) Switch
Push – transmits an identification signal.
Transponder Switch
TEST – the ATC FAIL light illuminates to indicate the selected transponder is
operational.

Note: Transponder modes are enabled only when the airplane is airborne, except for mode S, which operates continuously when the transponder mode selector is out of STBY.
ALT OFF – transponder operates without altitude reporting.
ALT ON – transponder operates with altitude reporting.
TA – enables display of traffic advisory TCAS targets.
TA/RA – enables display of traffic advisory and resolution advisory TCAS targets.

Push –
.
numeric switches – set transponder code in transponder
.
CLR switch –
.
first time clears display code
.
second time restores previous code.

Weather Radar Panel
Weather Radar Mode Switches
Push – selects mode.
.
TEST – shows test pattern on map display with WXR selected (except in PLAN mode) and tests transmitter (transmits only up to one second).
.
WX – shows weather radar returns at selected gain level
.
WX+T (turbulence) – shows weather radar returns and turbulence. Turbulence display is available on the EHSI if the selected map range is 50 nautical miles or less
Note: Turbulence detection requires presence of detectable precipitation. Clear air turbulence cannot be detected by radar.
.
MAP – shows ground returns at selected gain level
.
IDNT – suppresses ground return in WX and WX+T modes
Note: Continuous operation is not recommended because weather return intensity may be reduced.
.
STAB – stabilizes the system from the IRS, placing the antenna under
control of the receiver–transmitter to correct for changes in airplane
attitude.
GAIN Control
Rotate – sets gain in WX, WX+T, and MAP modes.
CAL (calibrated) – gain is set to calibrated level in the full counterclockwise position.
