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.

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.

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.

Measurement selection
switch
<single/progressive
lens>
switch the measurement mode:

measured.
determines the measurement value of the far point when the
addition is measured.
determines the far point for auto measurement of the progressive
lens.
For the manual measurement, determines the measurement
positions and values for the far and near points.
Memory/Add switch
Clears the measurement data by pressing it for a long time.
MENU switch corresponds to pressing two switches shown on the right at the same time. Shift
