Safety Precautions

As the microscope is a precision instrument, always handle it with care, avoiding impact

or abrupt movement during transportation. Do not shake the package.

Do not place the microscope in direct sunlight or in high heat. Keep it indoors in a dry

and clean place with temperatures between 32-100 degrees F (0-40 degrees C), and in

maximum relative humidity of 85%.

Avoid touching the lenses on the objectives and the eyepieces so that oil and dirt from

your fingerprints do not obstruct your view.

Before turning the power on, make sure that the power supply voltage is consistent with

the voltage of your microscope ring light.
