MAINTENANCE AND SERVICE
The maintenance described below should be
performed routinely so that the P
ACSCAN™ is
always operating in a safe and reliable manner.
In some cases (calibration check, probe
examination etc.) it is a good practice to carry
out the procedure prior to using the system every
time that it is powered-on. For example
checking the instrument cali
bration is necessary
if reliable measurements are to be made, while a
physical examination of the probe will lessen the
possibility of injury to the eye. In any event, a
routine consideration of all the items is a good
practice and may help to avoid major problems
in the future.
SYSTEM GENERAL INSPECTION
1. Be sure the instrument is located on a flat,
level and stable surface and in a comfortable
viewing position.
2. Examine each item for any defects or
damage.
3. Visually examine the instrument, prior to
use, for loose or disconnected cables or
cables which appear frayed or broken.
4. For electrical-shock protection, the AC
adapter should only be plugged into a
properly wired AC receptacle.
5. Verify that operational conditions are such
as to prevent either small objects or liquids
from entering the unit in order to prevent
component damage or a fire hazard.
6. Verify that the foot pedal functions properly,
is placed in a convenient location, and that
the cable is free from becoming entangled.

ROUTINE MAINTENANCE
CLEANING
System: Periodic cleaning of the PACSCAN™
with a soft cloth is all that is usually required to
keep the system looking new. Stubborn stains
may be removed using a soft cloth dampened
with a mild detergent solution.
CAUTION
Never use strong solvents such as benzene,
acetone, thinner or abrasive cleansers as these
may damage the system.
!
WARNING
To prevent electrical shock, it is recommended
that the power cord be disconnected prior to
cleaning the system.
!
Probes: Place the probe into a suitable
receptacle that allows the applanating surface
and adjacent 2-3 mm of the probe to be
immersed into 70% isopropyl alcohol. After a
five (5) minute soaking period, wash the probe
tip under running water and then dry. The
remainder of the probe and cord may be wiped
down with alcohol.
CAUTION
DO NOT soak probes in alcohol for extended
periods of time, as damage can occur.
!
STORAGE
When not in use, it is recommended that the
power cord be disconnected and the P
ACSCAN™
be covered to keep dust and debris from entering
the system. While stored the P
ACSCAN™
