The SL30 can be installed in several configurations based upon individual requirements. This
includes with or without an external course deviation indicator. The CDI may be discrete,
serial, or composite.

Com Transceiver

For standalone installations, the Com requires connections to:
• a standard Com antenna
• a microphone (or microphones)

The system can be configured to mix the NAV audio with the Com audio if no external audio
panel is used.
