●●Operating Precautions ●●
WARNING
Do not place heavy objects on the printer. Failure to observe this warning could
result in the unit becoming unbalanced and thus causing injury if it falls.
Do not put a heavy thing on the power and data cables. Fire, electrical shock, and
failure can be caused.
Do not operate at voltages other than 10.8 - 35.0 VDC. Failure to observe this
warning could result in fire, electrical shock, and/or malfunction.
If an unusual smell, smoke, or other abnormality is detected, immediately turn off the
power to the printer and then turn off the power on the power distribution panel of
the vessel. After confirming that the unusual smell, smoke, or other abnormality has
cleared up, consult your dealer or nearest JRC service/sales representative for
repair. Using the receiver in such situation may cause fire and/or electrical shock.

iv
CAUTION
Do not place the printer on an unstable surface. If placed on an unstable table or an
uneven surface, it could fall and result in personal injury and/or damage or
malfunction of the unit.
Fix the printer steadily using the supplied screws.
Do not expose to water or moisture. Placement on exposed decks or in humid
places may cause electrical shock or malfunction.
Do not open or remove the cover of the printer. Touching the parts inside could
result in electrical shock. If it is absolutely necessary to check the inside of the
receiver for maintenance, turn off the power of the power distribution panel.
Avoid exposure to direct sunlight, heat, moisture, and dust. Failure to do so may
cause fire, malfunction, and/or deterioration of print-out quality.
Always use the JRC-recommended printer paper. The use of any other paper may
cause printer trouble and/or deterioration of print-out quality.
When cleaning, do not use benzene, alcohol, thinner, or other volatile solvents.
The coated surface may deteriorate or be damaged. Wipe the surface lightly with a
soft cloth.
●●Operating Precautions ●●
