LINE VOLTAGE AND FUSE

To move the fuse, turn the fuse cap located on the line voltage selector in the direction
indicated by the arrow. Then remove the fuse plug from the unit. Put the fuse plug back so that
the proper line voltage marking can be seen through the cut in the edge of the plug.

Whenever the position of the selector is changed, check the rating of the fuse. A0.2-ampere
fuse is to be used for either 220V or 240V operation and a 0.3-ampere fuse for 110V, 120V or 130V
operation. If the rating of the fuse is correct, replace cap.

Fuse replacement

If the fuse blows, the fuse cap and replace the
fuse with a new one.

Take off the fuse cap by turning it with a coin,
etc. in the direction indicated by the arrow.
