Warning! 
Before replacing the rear panel fuse, disconnect the unit from the supply. Failure to 
do this may expose hazardous voltages. Unplug the unit from the local supply 
socket. 
1.  Ensure that power is turned off and the power cable is disconnected from the 
AC power inlet. 
2.  Ease out the fuse carrier by placing a small, flat-bladed screwdriver in the notch 
at the top of the carrier. 
Caution... 
When replacing the power input fuse, always ensure that a fuse of the correct type 
and rating is fitted. Failure to do so may result in inadequate protection. 
3.  Replace the fuse in the carrier. 
4.  Insert the fuse carrier back in the AC power inlet.
