Precautions Against Laser Radiation

As indicated in the Certification and Indication Label attached on the lower left-hand
side cover of the machine, the machine complies with "Laser Products - Conformance
with IEC 60825-1, Am. 2 and IEC 60601-2-22; Final Guidance for Industry and
FDA (Laser Notice No. 50) and NE60825-1 (Amendment 2)." The image reader
incorporates a laser with a maximum output of 50 mW (Class 3B, semiconductor laser
wavelength of 660 nm, red visible light), but you will not be exposed to any hazard if
you perform tasks as instructed in the service manual.
 Precautions Against Laser Exposure
Observe the following precautions to avoid laser exposure.
 Procedures that require precautions against laser exposure
When performing the following procedures, observe the instructions exactly as
described in this manual to avoid laser exposure. After the procedures are completed,
put the removed protective housings and screws back exactly in their original position
to prevent leakage of a laser beam out of the machine.
- Removal and reinstallation of the scanning optics unit.
- Replacement and cleaning of subscanning unit parts.
 Preventive maintenance for keeping the machine in compliance
In order to keep the machine in compliance, perform preventive maintenance
programs described in "Preventive Maintenance Volume" at intervals specified.
 Things that should not be done to avoid laser exposure
Observe the following precautions to avoid laser exposure.
- Never attempt to perform procedures other than instructed in this manual because
you may be exposed to laser beam radiation.
- Do not reflect a laser beam by placing a mirror or the like in the laser beam path.
- Do not alter the light path of a laser beam.
- Do not replace optical parts while the laser is energized.
- Do not attempt to make optical axis adjustment in the field. Although the
semiconductor laser beam is red visible light, field adjustment of the optical axis
cannot be done.

Precautions on Patient Environment

Before the machine is installed, the supervisor at the machine installation site (the
hospital's director) should check to see whether the machine is installed in the patient
environment or not.
 Additional Protective Grounding
If the CR-IR 362 is installed in the patient environment with the connected equipment
in the non-medically used room, the additional protective grounding will be required.
Definitions of "patient environment", "medically-used room", and "non-medically used
room" are given below.
 Patient Environment
Patient environment is the area for the patient to receive medical procedures (treatment,
tests, diagnosis, monitoring). It is the space measuring 2.5 m in all four directions and
2.5 m in height from the area of the patient's body.
It excludes the space traveled by the patient to reach the medically-used room.
 Medically-Used Room
Room equipped with protective grounding (medical use outlet or medical use
grounding terminal) implemented by the medical grounding method. The protective
grounding inside the medically-used room is equipotential, and the protective
grounding of this medically-used room is equipotential to that in the other medically-
used room.
Generally, a portion of the medically-used room is the patient environment.
 Non-Medically Used Room
Areas outside the medically-used room are considered the non-medically used room.
