Operating Requirements
All machines have two power on switches: one on the system unit (Media
Console for Type 2142) and one on the display. Some high voltage
machines (180–259 V ac) might have a power cord from the display to the
system unit and a non-switched appliance connector.
MM55 (Type 2116) and MM75 (Type 2168) monitors have universal auto
sensing power supplies.
When the system unit is powered off for 10 seconds or more and then
powered on, the power supply generates a “power good” signal that resets
the system logic.
Note: Whether or not Power Management is enabled, the on/off switch on
the system unit
does not
completely power-off the power supply. Also, the
appliance outlet connector is always powered on when the system unit is
plugged into an electrical outlet. See “Power Management” on page 1-21
for more information.
A Note About Energy Saver Monitors
Monitors rated as “Energy Saver” models use less than 30 W when
operating in the energy-saving mode or when the system unit is
powered off.
To extend monitor life, the monitor should be powered off at the end of
each day.
