TY91/TY92 VHF Radio Installation Manual 00839-00 11 April 2012 Issue AA 5.10 Wiring Considerations 5.10.1 TC90 Interconnect The connection from the TY91/TY92 VHF radio to the TC90 uses a minimum of six (6) signal lines; the TMAP pair, the Power and Ground pair, and the Remote On discrete line plus associated ground line. In a certified installation the normal wire choice would be Tefzel hook-up wire.
TY91/TY92 VHF Radio Installation Manual 00839-00 11 April 2012 Issue AA An alternative to a harness built from individual wires, particularly for a long cable run, is to use a multi-core cable. Aviation grade cable with 6 or more cores is often more expensive than the individual wires, and therefore is not generally a good choice for a certified aircraft. For aircraft where those considerations do not apply however, an attractive alternative solution may be to use 3 pair or 4 pair data cable.
TY91/TY92 VHF Radio Installation Manual 00839-00 11 April 2012 Issue AA The following considerations should be taken into account when siting the Antenna. The antenna should be well removed from any projections, the engine(s) and propeller(s). It should also be well removed from landing gear doors, access doors or others openings which will break the ground plane for the antenna. The antenna should be mounted in a vertical position when the aircraft is in level flight.

TY91/TY92 VHF Radio Installation Manual 00839-00 11 April 2012 Issue AA 6.2.2 Intercom Squelch The intercom includes a voice activated squelch control to limit the background noise heard over the intercom. Increasing the squelch level requires a louder microphone input to gate the intercom. 6.2.3 Auxiliary Input Volume The auxiliary input is a low-fidelity monophonic input intended for nav radio ident inputs and simple annunciators. This setting controls the relative volume of the auxiliary audio input.
TY91/TY92 VHF Radio Installation Manual 00839-00 11 April 2012 Issue AA 6.2.7 Frequency Step Size The TY91/TY92 is capable of operating in both an 8.33 kHz and 25 kHz environment.

TY91/TY92 VHF Radio Installation Manual 00839-00 11 April 2012 Issue AA 8.4 Tuning Knobs The right hand knobs are used to tune the radio. The large knob adjusts the MHz portion of the standby frequency, and the smaller knob adjusts the kHz portion of the standby frequency. Pressing the end of the small knob changes the channel spacing that the small knob operates through. If the radio is configured for 8.33 kHz operation, the steps toggle between 8.33 kHz channels and 25 kHz channels.

After you have stepped through all the loaded airports, or if there is no GPS attached, the built-in memory of the TC90 is displayed. The TC90 has nine frequency memories. Each frequency position can be selected by turning the SMALL tuning knob. Whether from a GPS or from the onboard memory bank, the selected frequency is loaded into the standby window.
TY91/TY92 VHF Radio Installation Manual 00839-00 11 April 2012 Issue AA Some FAULT indications can be recovered by switching the VHF radio off and back on again, although in all cases a FAULT code implies that there is a fault with the VHF radio or the installation. Note the FAULT message shown on the screen and pass that information to your avionics maintenance organisation.
TY91/TY92 VHF Radio Installation Manual 00839-00 11 April 2012 Issue AA 9. Continued Airworthiness Other than for periodic functional checks required by the regulations, the TY91/TY92 VHF radio has been designed and manufactured to allow “on condition maintenance”. This means that there are no periodic service requirements necessary to maintain continued airworthiness, and no maintenance is required until the equipment does not properly perform its intended function.
