Replacing the Fuse
If the unit will not turn on when plugged in and switched ON (via the
power switch), or you suspect a blown fuse, replace the fuse using the
following procedure:
1. Disconnect the AC power and place the power switch located
on the rear panel in the OFF position.
2. The fuse is located next to the power cord receptacle in the
upper left-hand corner of the rear panel. Remove the power
cord from the receptacle.
3. Insert a small flat-blade screwdriver into the slot in the
receptacle wall nearest the fuse and gently pry open the fuse
receptacle. The fuse holder will slide out. The fuse in use is
visible in the clip. To open the spare fuse compartment, push on
one end until it slides out.
4. Remove the bad fuse and replace it with a 5X20 mm 1A, 250V
fast acting fuse for AC units (TBE P/N F-1189 ), or 1/2A fast
acting fuse for DC units (P/N F-51).
