1.5.1 Control description
Key Description
POWER key Turns the system on or off. (Where the slide switch for MU-190/
MU-231 or MU-270 is ON, this also key turns the display unit on
or off.)
Status LED The color and state of the LED change according to system or
alert status.
Green, lighting: Normal operation status; no alerts generated.
Red, lighting: Acknowledged alert (but not rectified) or SYSTEM
FAIL. SYSTEM FAIL occurs when there is trouble in the Proces-
sor Unit or communication failure between the Processor Unit
and an ECDIS Control Unit. Each Control Unit detects trouble
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 rapidly: Alert not acknowledged nor rectified.
Red, flashing slowly: Alert not acknowledged but rectified.
OFF: The heater on the CPU board is on, because the ambient
temperature is not at least 0°C. The heater takes about two min-
utes to warm the equipment. The LED lights green after the heat-
er goes off.
