shock, do not perform any servicing other than what’s described in the operating
instructions unless you are qualified to do so.
6.1 Fuse Replacement

unit. Try to determine and correct the cause of the blown fuse then replace only with
the correct fuse. The fuse is located in a fuse compartment which is part of the AC
receptacle in the rear panel.
Replace the required fuses according to this table.

AC 220V 198V to 242V T 1A, 250V
