Replacing the Fuses
Should a power problem blow one or both of the fuses in the power
entry module on the rear panel, the fuse(s) will need to be replaced.
Before starting, the user will need a 5-mm or 3/16-in screwdriver.
To replace the fuse(s)
1. Disconnect device from AC power.
2. Remove AC power cord from the power entry module at the rear
of the Docking Station.
3. Using the screwdriver, gently pry loose the fuse cover in the left
portion of the power entry module, exposing the fuse holder.
4. Using the screwdriver, gently remove the fuse holder.
5. Note how the fuse(s) are placed in the fuse holder for installation
of the new fuse(s).
6. To remove the fuses from the fuse holder, use the edge of the
screwdriver blade to pry against the bottom of the metal portion
of the fuse where it is secured to the glass portion of the fuse.
7. Place the fuse(s) in the fuse holder, properly orienting the fuse(s).
