PRECAUTIONS

.Replncing the fuses
For continued protection against risk fire, replace only with same type and same rating fuse.

CIRCUIT N0. PART NO. DESCRIPTION
F901 252050 5A STG, Primary fuse (120V,120V/220V model)
F902,FQOS 252075 or 2,5A-SE-EAK or

252075CC 2,5A-SE7EAK, Primary fuse (220V,240V,120V/220V model)

2. Insulation resistance mesurement (Only U.S.A. model)
Connect the insulatingresistance tester between the plug of power supply cable and the terminal GND on the back panel,
Specifications; More than 10 M9 at 500V.

Voltage selector (rear panel)

Worldwide models are equipped with a voltage selector to conform with local power supplies. Be sure to set this switch to
match me voltage of the power supply in your area before turning the power switch on. Voltage is changed by sliding the
groove in the switch with a screwdriver to the right or left.

Confirm that the switch has been moved all the way to the right or left before turning the power switch on, Models with-
out a voltage selector can only be used in areas where the power supply is the same as that of the unit.
