Replacing AC Power Fuses
?
W
ARNING
!
The Encore contains high voltage (120 or 240
VAC) which can cause injury or death. Be sure to unplug the console from its
AC power source before performing any maintenance inside the console.

C
AUTION
:
You must replace fuses with new fuses of the proper type
and rating, or else your Encore console can be damaged. The only brand of
fuse that should be installed in the Encore is Wickman-Werke model 19195.
Any other kind of fuse will compromise the UL (Underwriter Laboratories)
safety compliance.
1.
Obtain the correct replacement fuse, which can be purchased from
your Colortran dealer as part #
29-00039 (4 Amp 250 Volt slow blow).
2.
Remove the AC power cord from the Encore Back Panel to access the
fuse holder, which is built into the AC power connector.
3.
Use a small screw driver to pry open the fuse holder. Remove the bad
fuse from the fuse holder, and snap the new fuse gently into place.
4.
Slide the fuse holder into the Back Panel until you feel it snap into
place.
Replacing the RAM Backup Battery
?
C
AUTION
:
Modern electronics can sometimes be permanently
damaged by just a tiny amount of static electricity, an amount much smaller
than you can feel! To protect your Encore from damage, it is recommended
that you use a grounding wrist-strap connected to the console chassis whenever
you remove the computer cover.
