SAFETY - 5

SAFETY SUMMARY
CAUTION Indications
Injury due to Gazing Directly at Xe Flash Lamp When Lit
•The Xe flash lamp radiates strong ultraviolet rays. Avoid
gazing at it directly when lit. For looking at the lamp, be sure
to wear goggles equipped with a function for cutting off
ultraviolet rays. (Sections 5.2)
Fatigue due to Long-Hour Operation
•If you keep working with the display monitor and keyboard for
long hours, your eyes and body will be fatigued to jeopardize
your health. When working with the display monitor for a
long time, take a break for 10 to 15 minutes per hour for the
health of your eyes and body. (Chapter 3)
Heavy Instrument
•This instrument weight as much as 15 kg. When carrying
this instrument, exercise care not to incur injury by dropping it
accidentally. Be sure to hold the right and left parts of the
instrument securely when moving it. (Sections 1.1)
SAFETY - 6

SAFETY SUMMARY
NOTICE
Disposal of Waste Solution
Be sure to collect waste solution and treat it for proper disposal
in accordance with the relevant laws and regulations regarding
water pollution control and sewage treatment.
Improper treatment of waste solution may result in environmental
pollution, and could also lead to a penalty.
Accuracy and Precision of Measured Values
Carry out periodic inspection and check whether the system is
operating normally. If necessary, conduct measurement on a
control sample.
Burst of a Lithium Battery
This spectrophotometer uses a lithium battery to backup the data
in the memory. A lithium battery may burst should it be handled
improperly. Be sure not to charge and dissolve it, or throw it to
the fire under any circumstance. It should be handled totally
separate from ordinary wastes.
When the lithium battery needs to be replaced (for example,
when an error message RAM NG is displayed frequently on the
screen), contact the dealer from whom you bought the
spectrophotometer or the nearest service department.
Please entrust the replacement to a service agent who finished
the technical training provided by our company.
(Replacement is charged after the warranty period of the
spectrophotometer.
SAFETY - 7

SAFETY SUMMARY
NOTICE (Continued)
Electrical Checkups
•Make sure that power supply to the spectrophotometer is
100 V AC, 1 kVA or more (50 or 60 Hz). Voltage fluctuation
or noise entering the power line may have an adverse effect
on the spectrophotometer main unit and cause a malfunction
as well.
•Be sure to prepare a grounding wire together with power
cables and confirm that the wire has a ground resistance of
100 Ωor less (Class D grounding construction in Electric
Facility Technical Standards). Insufficient grounding may
make the instrument susceptible to noise from the exterior
and cause a stray voltage to appear in the main unit, which
would be hazardous to personnel.
