4.1 Turning on and off the Power
CAUTION
• Checking the power supply voltage
If the AC power supply voltage is improper, abnormal volt-
age may damage the mechanism inside the equipment.
Confirm that the AC power supply voltage is within the
specified rating before turning on the MT8801C power.
The following shows the specified power supply voltage
and frequency:
Voltage: 100 to 120 Vac or 200 to 240 Vac (Because
an automatic input voltage rating switching
system is used, the rating need not be
switched.)
Frequency: 47.5 to 63 Hz
For normal MT8801C operation, leave the power switch on the rear panel set to on
when the AC power inlet is connected to the power outlet, and only use the Stby/On
switch on the front panel to turn the power on and off.
Check the power display lamps at the lower-left part of the front panel as listed in the
table below to confirm the power supply state.
