To prevent this, use the specified system connection cables in strict
accordance with the instruction manual. The instrument is designed to
minimize possible electromagnetic wave interference caused by it if the
specified cables are connected properly.
However, there is no guarantee that electromagnetic wave interference will
not be caused by the instrument. If the instrument does cause
interference to radio or television reception, which can be determined by
turning off and on the instrument, the user is encouraged to try to correct
the interference by one or more of the following measures:
Increase separation between the instrument and radio/TV receiver.
Connect the instrument to an outlet on a circuit different from that to
which the radio/TV receiver is connected.
（2）Possible Electromagnetic Wave Interference Affecting This Instrument
If this instrument is used near an intense electromagnetic source,
interference noise may be given to the instrument to incur an adverse effect
on its performance or functionality.This effect will be less than 1% and still
could be accepted.
To prevent this, use the specified system connection cables in strict
accordance with the instruction manual. The instrument is designed to
minimize possible electromagnetic wave interference affecting it if the
specified cables are connected properly.
However, there is no guarantee that electromagnetic wave interference will
not occur in this instrument. If the instrument does incur electromagnetic
wave interference, which can be determined by turning on and off possible
sources of electromagnetic wave interference nearby, the user is
encouraged to try to correct the interference by one or more of the following
measures:
Reorient the instrument.
Increase separation between the instrument and possible sources of
electromagnetic wave interference.
Increase separation between the power cable of the instrument and
possible sources of electromagnetic wave interference.
Connect the instrument to an outlet on a circuit different from that to

SAFETY SUMMARY
General Safety Guidelines
■Do not modify the product, replace parts that are not user-
serviceable, use non-specified parts, nor remove safety devices, as it
could be hazardous.
■Installation at delivery, maintenance and relocation should be referred
to our qualified service personnel.
■Do not perform any operation or action other than described in the
instruction manual. When in doubt, please contact our sales
representative or service office nearest you.
■When using a chemical for analytical operation, be sure to provide
proper ventilation in the laboratory room as per local requirements.
Inadequate ventilation could endanger human health.
Keep in mind that the hazard warnings in the manual or on the product
cannot cover every possible case, as it is impossible to predict and
evaluate circumstances beforehand.
Be alert and use your common sense.

SAFETY SUMMARY
This instruction manual contains the following cautious instructions.
DANGER
The warning “DANGER” does not apply to this product.
WARNING
Electric Shock in Contact with Dangerous High Voltage (500 V)
In contact with D2 lamp power supply voltage (500 V), you may receive an
electric shock to cause fatal or serious injury.
Before replacing the D2 lamp, make sure that the POWER switch of the
spectrophotometer main unit is turned off.
Electric Shock in Contact with Dangerous Voltage
In contact with power supply voltage (100-240V), you may receive an
electric shock to cause fatal or serious injury.
Before connecting the power cord, make sure that the POWER switch of
the spectrophotometer main unit is turned off.
CAUTION
Burn in Contact with High Temperature
The D2 lamp and WI lamp reach a high temperature.
They can burn you if touched.
Before replacing or adjusting the lamp, turn off the POWER switch and
wait until it cools down sufficiently.
Fatigue on Long Use
Watching the CRT screen in the same posture for a long time
accumulates fatigue in your eyes or body. For long use, take a 10 to
15-minute rest every hour for your health.
Oxygen Deficiency due to Presence of Nitrogen
■If nitrogen purging is carried out for long hours in a narrow room without
operating an exhaust duct, the oxygen concentration in the room will
decrease and an oxygen deficiency could result.
Be sure to operate an exhaust duct or else open a window during the
purge for ventilation purposes.

SAFETY SUMMARY
Remarks on safety of spectrophotometer
Electricity
(a) Confirm the power supply to the spectrophotometer is AC100-240V.
(50Hz or 60Hz).Power is more than 1 KVA.
Fluctuation in voltage or noise on the power line would not only affect
the spectrophotometer main unit adversely but also cause an accident.
(b) Be sure to provide grounding connection along with power connection.
Make sure that the spectrophotometer is grounded at a grounding
resistance of 10or less.
If grounding is improper, the spectrophotometer is easily affected by
external noise and floating voltage generated in it endangers physical
safety.
(c) High-voltage circuits are used inside the spectrophotometer.
Do not open any other cover than necessary for operation.
Fire
Avoid smoking and using a fire in the vicinity of the spectrophotometer.
Labels on spectrophotometer
There are warning labels of high pressure, high temperature on UV2600
Spectrophotometer. Pay attention to them during operation to avoid safety
accidents.
Back Up the Data
It is therefore recommended to back up the contents of the hard disk
beforehand.
To avoid misoperation, set space of more than 100 MB in computer
harddisk as work area for UV apllication software.
Computer Virus
If programs or data has suddenly been destroyed, if an unexpected
operation takes place or if an abnormal display appears on the screen,
your personal computer may have been infiltrated by a computer virus.
The computer virus is a rogue program that secretly invades a personal
computer and operates it willfully while destroying memorized data.
A program for eliminating the virus is called vaccine program.
There is a possibility of contamination with a computer virus by
downloading through communication a program including a computer
virus, or by using an exchangeable recording medium such as a floppy
disk that contains a computer virus. Also, it is possible to transmit the

PREFACE&SAFETY SUMMARY
10
virus from one personal computer to another via communication or
recording media. So avoid using a program or recording medium that
might include a virus.
Carry out check using a vaccine program if there is a possibility of
contamination with a virus. But depending on the type of vaccine
program, it may be impossible to eliminate the virus.
Personal Computer (PC)
Do not turn off the PC power supply alone. If the PC power supply is
turned off during access to the hard disk or floppy disk, the PC may
malfunction and the data or software stored in it may be destroyed. To
turn off the PC power supply, be sure to complete the spectrophotometer
control and data processing program (UV Analyst) before taking the
shutdown procedure for the system software.
Power Failure
A power failure or momentary voltage drop of the power supply due to
lightning, etc. may cause failure of the personal computer used with the
instrument and also damages the system software, application software
and other data.
To avoid such problems, it is recommended to use an AC uninterruptible
power source.
