telecommunications company cause to request the user to disconnect the
equipment.
Users should ensure for their own protection that the electrical ground connections
of the power utility, telephone lines, and internal metallic water pipe system, if
present, are connected together. This precaution may be particularly important in
rural areas.
CAUTION:
Users should not attempt to make such connections themselves, but should contact
the appropriate electric inspection authority, or electrician, as appropriate.
NOTICE:
The Ringer Equivalence Number (REN) for this terminal equipment is. The REN
assigned to each terminal equipment provides an identification of the maximum
number of terminals allowed to be connected to a telephone interface. The

Laser Safety
This is a digital machine which operates using a laser. There is no possibility of
danger from the laser provided the machine is operated according to the
instructions in this manual.
Since radiation emitted by the laser is completely confined within a protective
housing, the laser beam cannot escape from the machine during any phase of user
operation.
This machine is certified as a Class 1 laser product: This means the machine does
not produce hazardous laser radiation.
Internal Laser Radiation
Maximum Average Radiation Power: 36.903 µW at the laser aperture of the print
head unit.
Wavelength: 770-800 nm
This product employs a Class 3b laser diode that emits an invisible laser beam.
