Usage: The scope is folded and stored as in the package. Pull the Barlow lens all the way out. Point the objective lens to the object and look through from the eyepiece. Slightly push the Barlow lens in for focusing until you can see the object. Sometimes it is necessary to pull a bit outward again if you have pushed too much in. By pushing and pulling the Barlow lens bit by bit the image will be visible gradually. With slow and tiny motion, rotate the eyepiece bit by bit to push and pull the Barlow lens so as to reach a sharp-image. The motion for micro-adjustment of focus must be made slowly bit by bit.
Maintain: When cleaning the lens, please do use the special cotton cloth that attached with the monocular, or other soft and clean cloth. For removing the dirt or stain, please drop one or two drops of alcohol on the cotton cloth for cleaning. Please keep the monocular in the ventilated and dry place.
Notes: Forbidden to clean the inner parts of the monocular or disassemble it. Do not use the monocular to watch the sun directly for it will cause incurable injury to human eyes.
