2 SAFETY PRECAUTIONS
1 . Requirements for prior contact regarding repair
1 ) When conducting repairs described in the Service Manual or Service Manual Annex,
prior contact with NIDEK is not necessary.
2 ) When conducting repairs not covered in the Service Manual or Service Manual
Annex, prior contact with the NIDEK Service Department in writing is required.
3 ) When for some reason, repairs were conducted because they needed to be done
immediately, or other such circumstance, contact NIDEK as soon as possible in writ-
ing after conducting repairs to the device.
2 . General precautions
1 ) Repairs by the Service Manual or Service Manual Annex must be performed by per-
sonnel who have undergone training at NIDEK.
2 ) Conduct repairs according to the procedures described in the Service Manual or Ser-
vice Manual Annex.
3 ) Never wipe the covers using an organic solvent such as paint thinner.
Doing so may ruin the surface and impair the appearance of the device.
4 ) When conducting repairs, turn off the power switch and disconnect the power cord
from the wall outlet unless the power needs to be on.
5 ) A part emitting invisible laser beam (Class 3B laser) is used inside the device. (How-
ever, the device is classified as a Class 1 laser product indicating that the part does
not emit hazardous irradiation to the eye.)
3 . Cautions regarding power source and power cord
1 ) Disconnect the power cord by holding its plug. Do not place heavy objects on the cord
or coil the cord tightly.
A damaged power cord may cause fire or electric shock.
2 ) Occasionally clean the prongs of the power plug with a dry cloth.
If dust accumulates between the prongs, the dust could collect moisture, and short
circuit or fire may occur.
3 ) Fully insert the main power plug into an outlet. A fire may occur if the device is used
with improper connection.
4 ) Do not overload the electrical outlet. A fire may occur.
5 ) Be sure to use an outlet equipped with a ground terminal.
Electric shock may result in the event of device malfunction or power leakage.
6 ) Be sure to use a wall outlet that meets the power requirements.
If the line voltage is too high or too low, the device may not perform properly. Electric
shock, malfunction, or fire may result.
4 . Maintenance cautions
1 ) Never look directly at the beam from the phototransmitter ASSY (invisible laser: Class
3B laser) or block it with any part of the body.
2 ) Take antistatic precautions prior to repair.
3 ) Take proper care against electric shock during repair.
4 ) Tighten or loosen screws with proper tools.
5 ) Never drop parts or screws inside the device.
6 ) Prepare storage cases so as not to lose the removed screws or parts.
