OPERATIONAL OVERVIEW

This chapter provides an overview of the FELCOM 12 system.

The Communication Unit

The communication unit is the heart of the FELCOM 12 system, trans- mitting and receiving messages and alerting you to equipment fault.

On its front panel you should see the POWER switch and POWER lamp. Normally, the power is left on while underway.
