Control Description
Turns the system on or off. (With a FURUNO monitor unit, the monitor is also
turned on or off with this switch.)
Status LED The color and state of the LED change according to system or alert status.
Green, lighting: Normal operation status; no alerts generated.
Green, flashing: The heater on the CPU board is on, because ambient tem-
perature is not at least 0°C. The heater takes about two minutes to warm the
equipment. The LED lights green after the heater goes off.
Red, lighting: Acknowledged alert or SYSTEM FAIL. SYSTEM FAIL occurs
when there is trouble in the Processor Unit or communication failure between
the Processor Unit and an ECDIS Control Unit. Each Control Unit detects trou-
ble and its lamp flashes in red and the buzzer sounds. If this condition occurs
at the No. 1 ECDIS Control Unit, the SYSTEM FAIL signal is output.
Red, flashing: Unacknowledged alert or SYSTEM FAIL.
