SAFETY CONSIDERATION

General Precautions

 SLM-5000 is NOT a medical device.

 Fingerprints 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.

 When fingerprints or dust are attached onto such parts, gently wipe them with the supplied dust cloth.

 When 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.

 In 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.

 Never dismantle the instrument. Fire or physical

damage may result.

 In case of malfunction, never try to repair by yourself.

Unplug the power cord immediately and contact your local distributor.

RB-473-B02M

Precautions on power source

 The power cord must be grounded at all time.

 Avoid 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.

 Insert the power cord firmly into the outlet and the instrument. If not, fire or electric shock may occur.

 Keep the power cord clean without any dust or oil on it. The dirty terminal may cause malfunction or

fire.

 When 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.

 Always use SLM-5000 with the rated powe voltage. Using the instrument out of the rated voltage

range may cause malfunction or fire.

 When pluging and unpluging the power cord,

always hold the plug.

 Do not touch the plug when your hands are wet.

 When the instrument is not used for a long time,

unplug the power cord from the outlet.

Dust

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 awa y 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) SLM-5000 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.
