CAUTION
Always take great care when operating ACCUREF-K. Malfunction or damage to the instrument could
occur.
Cut the power immediately if malfunction occurs during operation. Damage to the equipment or
personal injury will result. Consult your dealer, if repair work needs to be carried out.
At no time attempt to remodel or disassemble ACCUREF-K. Damage to the instrument or personal
injury will result.
As ACCUREF-K is a precision optical instrument, operations must be carried out at all times by
experienced, authorized personnel. Damage to the equipment or personal injury will result.
Electromagnetic wave generated by TV, radio, mobile phone, radio transceiver, etc. may cause
malfunction of this instrument. This instrument may also generate noise in the TV, radio, mobile
phone, radio transceiver, etc.
Avoid introducing or installing instruments which may have adverse influence to the circumstance.
Avoid use this instrument adjacent to other instruments or stacked in plies. Failure or malfunction of
the instrument may occur.
Avoid installation near TV or radio. The reception can be disturbed by electrical noise. Follow the
manual for the proper installation.
Never remove the plug from the outlet if your hands are wet. Electric shock or personal injury could
result.
Make sure the power cord is not damaged. Fire or electric shock may occur.
Do not touch the optical parts. Measurement accuracy will be adversely affected.
The power cord must be firmly connected to an electrical ground (safety ground) at the power outlet.
Personal injury may result from electric shock, etc.
If the instrument fails to work properly, you should not try to repair the fault. Consult your dealer
immediately.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
ACCUREF-K9001 is used exceeds the applicable RF compliance level above, ACCUREF-K9001 should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating ACCUREF-K9001.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

2. Conveyance and Handling Procedure
be carried out.
When transporting the instrument, make sure that the body has been securely locked.
Center the body onto the base so that their edges are aligned. Push up the lock while turning right until
both body and base are firmly fixed to each other.
3. Installation Environment
1) Do not expose the instrument's view window directly
to the sunlight or bright lighting from other sources.
Great care should be taken and avoid that the
examinee is exposed to strong light or glare. The
pupil will contract too much for measurement to
2) Do not operate in places where either dust or rubbish
accumulates. Environment with extremes in heat and
humidity should also be avoided.
Always follow the environmental requirements below
for installation.
Temperature +10 °C ~ + 40°C
Relative Humidity 30 % ~ 85 %
3) Keep away from inflammable or explosive gases as
well as storage areas housing medical supplies and chemicals.
4) Avoid installing where dew condensation may accumulate.
Also, avoid where the radical temperature changes may
occur.
5) Keep away from sites that may experience strong vibrations
or sudden shocks.
6) Malfunction is likely to occur if the instrument is improperly stabilized or accidentally overturns.
To prevent internal/external damage caused by sudden impact, set the instrument on a solid and
secure surface. Do not store in high, 'out of reach' places.

4. Safeguard Summary
1. ACCUREF-K is a precision optical instrument. Always handle with care and avoid dropping it
accidentally.
2. Ensure that the instrument is properly grounded when connected to the power source.
3. Do not touch the optical parts with fingers and be sure to avoid dust, as their measuring accuracy
could be adversely affected and incorrect values may result.
When dust or fingerprints appear on the optical part, use a soft cloth to wipe off
the build-up. In case that the build-up is hard to remove, absolute alcohol is
recommended. Take great care when cleaning these parts as they are particularly
sensitive and fragile.
4. If the surfaces of the measuring unit and main unit including the
control panel are dirty, gently wipe with a dry cloth. For hard to
Thinner
remove stains, a damp cloth or neutral cleanser is
recommended.
Avoid using organic solvents that will
damage the water based paint finish of
the instrument.
Benzene
5. Clean the chin rest and head rest with the neutral cleanser. For disinfecting them, especially where the
examinee may contact, hydrogen peroxide (Oxydol) is recommended.
6. If the instrument is not used for any length of time, remove the
power cord from the outlet.
7. When not in use, protect the instrument with a supplied
dustproof cover.
8. When the instrument fails to function properly, never
attempt to perform internal service or adjustment. Contact
your nearest registered agent, distributor or retail outlet.

5. Preparation
5.1 Setting
(1) Set a roll of printer paper in the printer. Refer to '11.1 Reloading Printer Paper' for the procedure.
(2) Set and fix the chin rest liners with the chin rest
liner pins on the chin rest. Refer to the figure on
the right.
For sanitary consideration, disposing
