2 Inspection, Care, and Maintenance
Take the following steps to get the best results from the instrument:
l
Do not subject the equipment to rough jolts or careless treatment.
l
Keep the lenses and reflectors clean. Use only lens paper or other material that is designed for
cleaning optical equipment. A cleaner with a solution of pure water and 20-30% 2-Propanol
specified with evaporation residue <5mg/l is recommended.
l
Keep the instrument protected and in an upright position, preferably in the instrument case.
l
Do not carry the instrument while the instrument is mounted on a tripod. Doing so can damage the
tribrach screws.
l
Do not carry the instrument by the telescope barrel, please use the handle.
l
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.
Cleaning
Be very careful when cleaning the instrument, especially when removing sand or dust from lenses and
reflectors. Never use a coarse cloth, a dirty cloth, or hard paper to clean the instrument. Spectra
Geospatial recommends that you use anti-static lens paper, a cotton wad, or a lens brush.
CAUTION – Never use strong detergents such as benzine or thinners on the instrument or the
instrument case.
Care of the Screens
Clean the screens with a dust-free cloth and gently wipe the screen. Use the provided dust-free cloth in
the screen protector package.
CAUTION – Do not use abrasive cleaners and do not apply any Cleaning Solution directly on the
screen.
