Care and maintenance
WARNING – Do not remove the instrument cover from the instrument. The instrument is designed to withstand normal electromagnetic disturbance from the environment but it contains circuits that are sensitive to static electricity. If an unauthorized person opens the instrument cover, the function of the instrument is not guaranteed and the warranty is invalidated.
The instrument is designed and tested to withstand field conditions, but like all precision instruments, it requires care and maintenance. Take the following steps to get the best results from the instrument:
-
Do not subject the equipment to rough jolts or careless treatment.
-
Keep the lenses and reflectors clean. Use only lens paper or other material that is designed for cleaning optical equipment. As a cleaner, a solution of pure water and 20-30% 2-Propanol specified with evaporation residue <5mg/l.
-
Keep the instrument protected and in an upright position, preferably in the instrument case.
-
Do not carry the instrument while the instrument is mounted on a tripod.
-
Do not carry the instrument by the telescope barrel. Use the handle.
-
When you need extremely precise measurements, make sure that the instrument has adapted to the surrounding temperature. Significant variations in instrument temperature can affect precision.
