Fasteners
Installation of the HC4 is unique to every aircraft. It is left to the installer to provide the properly certified fasteners
for the application.
5.3
Mounting the Transmitter
The HC4 transmitter should be mounted in aircraft or other craft using the BMS-supplied mounting bracket (BMS
P/N 4414414000). The transmitter/bracket assembly must have adequate space above and below the unit to
allow free air flow. Three thermostatically controlled fans contained within the HC4 chassis keep the unit at
operating temperature.
1. Place the transmitter so that the two holes on its rear side fit the pins on the mounting bracket.
2. Tighten the mounting screw fasteners. Ensure the round nut captures the mounting bracket on the transmitter.
