Care and Maintenance
C
Warning – Do not remove the instrument cover from the instrument. A Spectra Precision
FOCUS 30 Total Station 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 Spectra Precision FOCUS 30 Total Station 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 result 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. A cleaner with a solution of pure
water and 20-30% 2-Propanol specified with evaporation residue <5mg/l is
recommended.
• 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. Doing
so can damage the tribrach screws.
• Do not carry the instrument by the telescope barrel, please 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.
Cleaning
B
Tip – 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 Precision recommends that you use anti-static lens paper, a
cotton wad, or a lens brush.
C
Caution – Never use strong detergents such as benzine or thinners on the instrument or
the instrument case.
Care of the Screens

Tip – Clean the screens with a dust-free cloth and gently wipe the screen, use the pro-
vided dust-free cloth in the screen protector package.
