Line Fuse

If the dc source appears "dead" with a blank display and the fan not running, check your power source to

be certain line voltage is being supplied to the dc source. If the power source is normal, the fuse may be

defective.

1. Turn off the front panel power switch and unplug the power cord.

2. Remove the fuse from the rear panel.

3. If the fuse is defective, replace it with a fuse of the same type (see Input Connections in chapter 3).

4. Turn on the dc source and check the operation.

NOTE: If the dc source has a defective fuse, replace it only once. If it fails again, the dc source

requires service.
