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).
