If wrong, transfer your original COM frequency back to Active, then repeat the turn
OFF, turn ON, and the detent-by-detent channel selection.
2.10 POST INSTALLATION TESTS
This operation procedure presumes that the MK-12DR has been installed with the
Keep-Alive option. All references to figures for adjustments refer to figures in the
MK-12D maintenance manual.
The purpose of this series of tests is to assure proper operation of the installed
avionics equipment. First, and most important, is a complete inspection of the
installation to be sure that all aircraft flight controls operate freely with full travel or
deflection.
Since these procedures cover Units with and without glideslope, simply bypass those
functions (glideslope) which do not apply to the system being tested. A remote
mounted Marker Beacon or Glideslope Receiver whose operation is dependent upon
the NAV Unit being tested should be considered as an integral part of the system and
included in this procedure. If an audio control panel is part of the installation,
remember to select the NAV and MKR audios at the appropriate points in the
procedure.
