NOTICE
Do not use aggressive cleaning agents!
Do not use photographic lens cleaners and no perfume-impregnated, dyed or lotion-soaked cloths to
clean optical surfaces. By the use the optics can take permanently damage!
• Protect the device from dust and moisture!
• Avoid fingerprints and similar contamination of the optical surfaces.
• The residual moisture must be completely degraded before use.
• Do not clean the optics too often! A little dust on the front of the lens or mirror surface will not signi-
ficantly reduce the image quality. This is no reason for cleaning.
• If necessary, carefully remove dust on the front of the lens or mirror surface with a camel hair
brush or blow away with compressed air.
• Remove organic soiling (e.g. fingerprints) with a cleaning liquid (mixing ratio: three parts distilled
water, one part isopropyl alcohol). Add a small drop of biodegradable dishwashing detergent per
half liter of cleaning liquid. Use soft, white face tissues and carefully clean surfaces with short, ra-
dial wiping movements. Replace the tissues as often as possible.
• If the air humidity is high, the glass may fog up and moisture may form. This is not a defect! In this
case, allow the device to acclimatise at room temperature for some time so that the residual hu-
midity can be reduced.
• Once the residual moisture has been completely removed, fit the dust caps and store the tele-
scope in a closed container* in a dry, mould-free place. It is recommended to store accessories in
a closed container with desiccant.
• (Depending on the model, a case may already be included in the scope of delivery)
