NOTES ON HANDLING AND SAFETY

Handle with care

• This product is high quality optical instrument. Delicate handling is required.

• Avoid subjecting it to sudden shocks and impact.

• Impacts, even small ones, can affect the precision of the objective.

Handling the LED

Note: Always disconnect the power cord from your microscope before handling the LED bulb and

power unit and allow the system approximately 35 minutes to cool down to avoid burns.

• Never touch the LED with your bare hands.

• Dirt or ngerprints will reduce the life time and can result in uneven illumination lowering

the optical performance.

• Use only original replacement LEDs.

• Use of other products will cause malfunctions and void warranty.

• During use of the microscope, the power unit will get hot, never touch it while in opera-

tion and allow the system approximately 35 minutes to cool down to avoid burns.

Dirt on the lenses

• Dirt on or inside the optical components such as eyepieces, lenses, etc., affect the
image quality of your system negatively.

• Always try to prevent your microscope from getting dirty by using the dust cover, prevent
leaving ngerprints on the lenses and clean the outer surface of the lens regularly.

• Cleaning optical components is a delicate matter. Please read the cleaning instructions

on our website carefully.

Environment, storage and use

• This product is a precision instrument and it should be used in a proper environment

for optimal use.

• Install your product indoors on a stable, vibration free and level surface.

• Do not place the product in direct sunlight.

• The ambient temperature should be between 5 to +40ºC and humidity is maximum
80% at 31 degrees decreasing linearly to 50% at 40 degrees. Although the system is

anti - mold treated, installing this product in a hot, humid location may still result in
the formation of mold or condensation on lenses, impairing performance or
causing malfunctions.

• Never turn the right and left focus knobs in opposite directions at the same time or turn

the coarse focus knob past its farthest point, this will damage this product.

• Never use undue force when turning the knobs.

Environment, storage and use (continued)

• Make sure that the microscope system can dissipate its heat.

• Keep the microscope approximately 15cm free from walls and obstructions.

• Never turn the microscope on when the dust cover is in place or when items are placed

on the microscope.

• Keep ammable uids, fabric etc. well out of the way.

Disconnect power

• Always disconnect your microscope from power before doing any maintenance, cleaning,
assembling or replacing LEDs to prevent electric shocks.

Prevent contact with water and other uids

• Never allow water or other uids to come in contact your microscope, this can cause

short circuiting your device, causing malfunction and damage on your system.

Moving and assembling

• The MT - 420 and MT - 430 microscopes are relatively heavy systems, consider this when

moving and installing the system.

• Always lift the microscope by holding the main body and base of the microscope.

• Never lift or move the microscope by its focusing knobs, stage or head.

• When needed, move the microscope with two persons instead of one.
