2.2 Checking the Power Voltage
18
The power voltage specification of the unit is set as specified when the unit was
ordered.
You can select from 100 V, 120 V, 220 V, and 240 V.
You can determine which voltage is set by checking the positions of the voltage
selectors.
Refer to the diagram between the voltage selectors.
2.2 Checking the Power Voltage
• Before turning the unit on, make sure the supply voltage matches that
indicated on the its power connector. Connection to an improper sup-
ply voltage may damage the unit and present an electrical hazard.
• The power of the unit can be changed with the voltage selectors. To
avoid an electric accident, use the unit with the voltage selectors set to
a voltage value that matches the voltage to be used.
• Make sure the power is off when you change the voltage with the volt-
age selectors. Changing the power voltage when the power is on may
result in damage to the unit or an electric accident.
• The maximum rated power is 110 VA.
• Replace the fuse only with one of the specified characteristics and volt-
age and current ratings. Using a non-specified fuse or shorting the
fuse holder may cause a life-threatening hazard.

In the diagram, the voltage
value is 100 V because
both the left and right volt-
age selectors are set to the
right side.
