•
Slide the VHF radio into the secured mounting tray.
•
Lock the VHF radio into the mounting tray using a 3/32” Allen key, gently hand tighten the
locking screw.
5.3 Cooling Requirements
The VHF radio meets all applicable ETSO requirements without forced air-cooling. Reasonable air
circulation should be provided.
Attention should be given to the incorporation of cooling provisions to limit the maximum operating
temperature if the TY96 is installed in close proximity to other avionics. The reliability of equipment
operating in close proximity in an avionics bay can be degraded if adequate cooling is not provided.
5.4 Electrical Connections
The TY96 has single 25 way D-type connector which is used for all the data and audio signals. A
single coaxial BNC is used to connect the antenna.
