2.6.2 Electrical Load Considerations
The Avidyne coupler will be connected to the airplane electrical power
system on the same circuit breaker as the associated VHF comm
transceiver and should be wired to carry the full load of the circuit
breaker. The coupler may be damaged if the VHF comm system
attempts to transmit without power applied to the coupler. Connecting
the coupler to the VHF comm circuit breaker ensures that the two units
will be powered at the same time.
