Installation
5.1 Unpacking and Inspecting Equipment
Carefully unpack the VHF radio and make a visual inspection of the unit for evidence of any damage
incurred during shipment. If the unit is damaged, notify the shipping company to file a claim for the
damage. To justify your claim, save the original shipping container and all packaging materials.
5.2 Installation Overview
The TY96/TY97 VHF Radio must be mounted rigidly in the aircraft panel. The following installation
procedure should be followed, remembering to allow adequate space for installation of cables and
connectors.
•
Select a position in the panel that is not too close to any high external heat source. (The radio
is not a significant heat source itself and does not need to be kept away from other devices for
this reason).
•
Prepare the instrument panel to ensure the radio mounting tray can be secured using the
mounting holes in the tray. The front edge of the mounting tray should sit flush with the
instrument panel.
•
It is advisable to complete the 25 way D-sub cable harness at this point before securing the
mounting tray into the aircraft. The cable harness and antenna connector can then be secured
to the removable mounting tray plate. Refer to section 5.4 for cable harness details and
section 5.5 for fitting the antenna connector.
•
Route the mounting tray plate and cable harness into position, avoiding sharp bends and
placing the cables too near to the aircraft control cables.
•
Attach the VHF antenna coax using a BNC connector.
•
Clip the mounting tray plate into the mounting tray and secure with M2.5 pan head screws.
Note: The mounting tray plate clips into the mounting tray to aid assembly but must be
secured using screws. The clips alone are not strong enough to retain the back plate when
fitting the radio.
•
Secure the mounting tray to the instrument panel via the six (6) mounting holes in the tray. It
is important that the tray is supported at the rear with at least two mounting holes as well as
the front four.
•
Check that the VHF radio locking mechanism is correctly oriented by unscrewing the locking
screw using a 3/32” Allen key.
