SAFETY CONSIDERATION
nGL-7000 is NOT a medical device.
nFingerprints or dust on the optical parts such as lenses may affect the measurement accuracy. Always
avoid touching such parts with fingers and keep away from dust getting on them.
nWhen fingerprints or dust are attached onto such parts, gently wipe them with the supplied dust cloth.
nWhen water or any liquid gets on the instrument, or
when any foreign matters gets inside the instrument,
unplug the power cord immediately and contact your
local distributor.
nIn case of occurrence of abnormality (noise or smoke),
unplug the power cord immediately and contact your
local distributor. Using the instrument in such a
condition may cause fire or physical damage.
nNever dismantle the instrument. Fire or physical
damage may result.
nIn case of malfunction, never try to repair by yourself.
Unplug the power cord immediately and contact your
local distributor.
General Precautions

RB-501-B02A
nThe power cord must be grounded at all time.
nAvoid damaging the power cord (such as bending it in an extremely small size, pulling, placing a
heavy object on it). When the power cord is damaged (breaks, damage of cover, etc), replace it to a
new cord to prevent any electric shock or fire from ocurring.
nInsert the power cord firmly into the outlet and the instrument. If not, fire or electric shock may occur.
nKeep the power cord clean without any dust or oil on it. The dirty terminal may cause malfunction or
fire.
nWhen the power cord becomes hot after used, check for the dirt at the terminal part. If you find no dirt,
replace the power cord to a new cord. The dirty terminal may cause malfucntion or fire.
nAlways use GL-7000 with the rated powe voltage. Using the instrument out of the rated voltage range
may cause malfunction or fire.
nWhen pluging and unpluging the power cord, always hold the plug.
nDo not touch the plug when your hands are wet.
nWhen the instrument is not used for a long time, unplug the power cord from the outlet.

2. Installation Environment
1) Do not expose the optic parts, i.e. lens stand, directly to
sunlight or bright light from other sources.
Strong light or glare to the instrument may cause the
failure of measurement.
2) Do not install the instrument in places where either dust
or rubbish may accumulate.
3) Environments with extremes in heat and humidity
should also be avoided.
Temperature range for use: 10°C ~ 40°C
Temperature range for storage: -10°C ~ 60°C
Humidity range for use/storage: 70%HR (no dew condensation allowed)
4) Keep away from inflammable or explosive gases as well as storage areas of medical supplies and
chemicals.
5) Keep away from sites that experience strong vibrations
or sudden shocks.
6) Malfunction is likely to occur if the instrument is not
properly stabilized of accidentally overturns. To prevent
internal/external damage caused by sudden impact,
install the instrument on a surface that is solid and
secure. Do not store in high, ‘out of reach’places.

Gases

3. Safeguard Summary
1) Ensure the instrument is properly grounded when connected to the power source.
2) Do not touch or allow dust to settle on the optical parts (i.e. lenses), as their measuring accuracy could
be adversely affected and incorrect value may result.
3) If the surfaces of the measuring unit and main unit
including the operation switches are dirty, gently
wipe with a dry cloth. For hard to remove stains, a
damp cloth or neutral cleanser is recommended.
4) GL-7000 is a precision optical instrument. Handle
with care at all times, making sure not to
accidentally drop it.
5) If the instrument is not to be used for any length of
time, remove the power cord from the outlet.
6) When not in use, the instrument should be protected
with the provided dustproof cover.
7) If the instrument fails to function properly, do not
attempt to perform internal service or adjustment.
Contact immediately your nearest registered agent,
distributor or retail outlet.
When dust or fingerprints appear, use the supplied dust cloth or a soft
cloth to gently wipe off the build-up. Take great
care when cleaning these
parts, as they are particularly sensitive and fragile.
At no time use organic solvents
which will damage the water based
paint finish of the instrument.

6.2. Lens without frames
(1) Place a lens on a lens stand. Lower the lens holder
softly on the lens.
The screen as shown on the right will appear.
(2) Move the lens and bring the cross cursor to the
alignment mark. The message "Alignment OK" will
appear on the screen when alignment completes.
The alignment mark represents the optical center of
the lensmeter and the cross cursor that of the lens.
(3) Move the lens until the cross cursor and the
alignment matches. When they match,the message
"Marking OK" will appear to indicate that marking
is ready to be carried out.
