ELT Remote Switch and Indicator Panel
The ELT remote switch and indicator panel located immediately below
the circuit breaker panel, provides test and monitoring functions for the

mounted in the panel powers the LED. The battery must be replaced
at regular intervals (refer to Airplane Maintenance Manual).
