5.0 MAINTENANCE, continued
5.3 Fuse Replacement
A. Under normal use, the fuse should not require replacement. The purpose of the
fuse is to protect the electronics from failure due to inrush.
B. Should it become necessary to change the fuse, replace with the same type (3
Amp/slow blow in most machines) to insure long life and performance.
C. On the back of the Illuminator Box, next to the Power Cord Plug, there is a small
plastic Fuse Holder. Gently pry the Holder up using a small screwdriver. Pull
completely out and replace the Fuses with the appropriate voltage Fuse.
Replace into the Illuminator Box, ensuring a snug fit.
5.4 Nosepiece Adapter Insert
A. If use of a different diameter Light Guide is needed a Nosepiece Adapter Insert
is necessary. To purchase additional Adapter Inserts, contact Galiso, Inc at
B. To install the new Nosepiece Adapter, unscrew all three Thumb Screws. Turn
the Illuminator Box over to allow the Adapter to fall out. Insert the new
Nosepiece Adapter and re-tighten the Thumb Screws.
5.5 Troubleshooting
If the problem is not resolved by performing the following suggestions, please call
Galiso, Inc. at (800) 854-3789 or (970)249-0233.
A. Light has low output, Fan operates:
1. Check the lamp to ensure that it is fully seated and connected. See Section
5.2 Lamp Replacement.
2. Check to make sure the Light Guide is fully seated in the Nosepiece.
3. Check the intensity setting.
4. Check the Lamp. A partial short in the Lamp may cause low or intermittent
output.
B. Output is intermittent; Fan operates (Lamp turns on and off every few minutes.)
1. The Illuminator Box may be running too hot. (A thermal cutoff protects the
circuitry from heat failure.
2. Check air intakes and exhaust areas for dust or dirt accumulation. Make sure
minimum clearances are maintained. (See Section 3.1 Assembly and
Placement, for clearance information).
3. Move the OPTI-LITE to another location.
