10.2 Replacing the Power Fuse
• To avoid an electric accident, be sure to turn the power switch off and
disconnect the power cord before replacing the fuse or switching the
power voltage.
Afterwards, be sure to check that the power voltage set for the power
switch with power selectors on the rear of the unit and the voltage to be
used match before reconnecting the power cord.
• 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.
Fuse type: 100 V 120 V setting: 250 V F1.0AL

5 mm x 20 mm
220 V 240 V setting: 250 V F0.5AL

5 mm x 20 mm
• Prior to shipment, the power voltage is set and the fuse designated for
that power voltage is included (same applies for the spare fuse). If you
want to set another power voltage, be sure to replace the fuse with one
of the designated rating.
• If you want to use a power voltage other than one indicated, set the corre-
sponding power voltage setting shown below.
