ADF/DME TUNING
The optional BendixKing KR-87 ADF is not tuned by
the G1000 system. Refer to the Honeywell BendixKing
KR 87 ADF Operators manual for ADF information. ADF
volume is also adjusted through the KR 87.
The G1000 system tunes the optional DME transceiver.
The UHF DME frequency is paired with a VHF NAV
frequency, providing DME distance information.
Frequency pairing is automatic and only the VHF NAV
frequency is shown on the display.
DME TUNING
The DME radio is tuned by selecting the associated
NAV system or HOLD in the DME Tuning window. The
DME Tuning window is located to the right of the HSI on
the lower right corner of the PFD. Pressing the top-level
DME softkey toggles the DME Tuning window ON and
OFF.
NOTE: When another Auxiliary window is
turned on, the DME Tuning window is replaced
on the PFD.
