The PC687 is designed to give you years of trouble-free service. There are
no user-serviceable parts inside. Except for the fuse in the DC power cord,
no maintenance is required.
To replace a blown fuse:
1. Press ends of the fuse holder together. Twist to open. Carefully
separate the two pieces.
2. Remove the fuse and inspect. If blown, replace with the same
type fuse.
Use only the fuse specified for your PC687. Failure to do so may void your
warranty.
