recommended to read the manual carefully in order to familiar-

ize yourself fully with the use of the microscope, so that you can obtain optimum per-

formance from it.

IMPORTANT

Observe the following points carefully:

Operation

1. Always handle the microscope with the care it deserves, and avoid abrupt motions.

Avoid exposure of the microscopetodirect sunlight, high temperature* and humidity,

dust and vibration.

If the microscope is used in an ambient temperature higher than 40°c (104"F), it

may cause a trouble to the microscope.

Only use the tension adjustmentringfor alteringthe tensionof the coarse adjustment.

Do not twist the two coarse adjustment knobs in the opposite directions simultane-

ously, which might cause damage.

4. Ascertain that the line voltage selector switch on the base plate is set to conform with

the local mains voltage.

Maintenance

1. Lenses must always be kept clean. Fine dust on lens surfaces should be blown or

wiped off by means of an air blower or aclean brush. Carefullywipe'off oil or finger-

prints deposited on the lens surfaces with gause moistened with a small amount of

xylene, alcohol or ether.

Do not use organic solutions to wipe the surfaces of various components. Plastic

parts, especially, should be cleaned with a neutral detergent.

Never disassemble the microscope for repair. Only authorized Olympus service per-

sonnel should make repairs.

The microscope should

stored in its container immediately after use. If this is not

possible, it should be covered with'a vinyl dust cover.

*Do not replace filters for about a few minutes after use, in order to give time to cool.

**The circuit breaker protrudes its central part to cut off the electrical power in case of the

dimmer circuit trouble (due to short circuit, etc.) or overcurrent. To restorethe breaker, press
