2 SAFETY PRECAUTIONS
1 . General precautions
1 ) Servicing must be performed by NIDEK service persons or other qualified personnel.
2 ) In case the system cannot be repaired by the procedures described in this manual,
please report the serial number of the system and details of the symptom or symp-
toms.
3 ) Observe the procedures described in this manual.
4 ) Failure to do so may cause accident or malfunction.
5 ) When performing maintenance work, turn off the power switch and disconnect the
power cord from the wall outlet unless the power needs to be on.
6 ) Never wipe the covers using an organic solvent such as paint thinner. Doing so may
ruin the surface and impair the appearance of the system.
2 . Maintenance cautions
1 ) In case of the system malfunction, check the symptom and turn off the power switch.
2 ) Do not drop parts or screws inside the system, nor bump it against surrounding
objects.
3 ) Prepare storage cases so as not to lose the removed parts or screws.
4 ) Tighten or loosen screws with proper tools.
5 ) After loosening the screws fastened by a threadlocking adhesive, be sure to reapply
the threadlocking adhesive to the screws when retightening them.
6 ) After replacing parts, confirm that they are fastened in their original positions securely
before turning on the power.
7 ) Should you observe smoke or strange odors being issued from the system, immedi-
ately turn off the power switch, disconnect the power cord from the outlet, and investi-
gate the cause.
8 ) If the system is powered in abnormal conditions, fire, electric shock, or total loss of the
system may result.
9 ) See Wiring Diagram and Connecting Cable to check cable breaks as described in
TROUBLESHOOTING. In addition, check cables for the following:
a . Connectors are connected and crimped properly.
b . No contact failure occurs after re-connection of connectors.
c . Cables are soldered properly.
* Do not yank the cables with excessive force.Doing so could cause cable break-
age.
* Never perform servicing with wet hands. Doing so could cause electric shock or
malfunction.
10) The labeled area indicates high voltage. Take proper precautions against electric
shock.
11 ) When a cable with any of the following marks is disconnected and reconnected, be
sure to confirm that the screws are tightened securely.
a . Protective ground
b . Functional ground
c . Equipotential

3 . Adjustment precautions
1 ) Confirm that the following conditions are met before installation.
a . A place which is level and stable without vibration and shock
b . No exposure to direct sunlight or ultraviolet rays
c . A place with minimal external light source
d . No exposure to water
e . A place where temperature and humidity meet the specifications for use
2 ) Never use the adjustment jigs for purposes other than those intended.
