Inspecting and Cleaning
CAUTION
Turn off the console
before inspecting any
delivery device
components.
CAUTION
Always handle the fiber-
optic cable with extreme
care.
Do not wrap the
cable in a diameter less
than 15 cm (6 in)
.
Damage to the fiber can
impair light transmission
through the fiber-optic
and reduce power.
CAUTION
Keep the protective cap
over the fiber-optic
connector when the
TruFocus LIO+ is not
in use.
Routine care
•
Do not tightly kink or bend the fiber-optic.
•
When connected to the console, ensure that the fiber-optic is located
away from high traffic areas.
•
Keep the dust window and the hand held aspheric lens free of
fingerprints.
Inspect the TruFocus LIO+
Frequently inspect the TruFocus LIO+ for dirt, debris, and damage.
Clean the fiber-optic connector
If needed, clean the fiber-optic connector using a cotton swab moistened
with 100% methanol (preferred) or 100% isopropyl alcohol. Place the
protective cap on the fiber-optic connector.
Clean the external surfaces
Wipe headpiece surfaces with a soft cloth dampened with a mild detergent.
Clean the hand held aspheric lens
Follow the manufacturer’s instructions for cleaning the handheld aspheric
lens.
Clean the binocular eyepieces
Moisten a lens tissue with lens cleaner and gently wipe the eyepieces to
remove fingerprints or debris.
Clean the dust window
1. Wrap a lens tissue around one end of a cotton-tipped swab.
2. Place several drops of 100% ethanol, 100% methanol, or high-grade
acetone on the tissue.
3. Wipe the lens gently with the swab to remove all dust and debris.
4. If the surface is still not clean, put a clean lens tissue around the end of
the swab and gently wipe it again.
