MAINTENANCE
Read This Section Before Use!
The Electrical Digital Theodolite is a precision instrument.
Do not subject it to shocks or excessive vibration.
Do not loosen or remove any screws unless specifically
required.
Do not carry the instrument mounted on the tripod on your
shoulder.
Avoid prolonged exposure to the sun or the heat of a closed
vehicle. Failure to do so may adversely affect the
efficiency of the instrument.
If the instrument has been used in wet conditions,
immediately wipe off any moisture and dry it completely
before replacing it in its carrying case. Exposure to
moisture or/and dust may cause severe instrument damage.
Sudden changes in temperature, such as caused by
bringing the instrument into a warm room from the cold
outdoors, can cause internal condensation. This may
result in reduced measuring accuracy or electrical system
failure. Should this occur, leave the instrument in a warm
location with the carrying case closed until the temperature
of the instrument returns to room temperature.
Avoid storing the instrument in hot, humid conditions. The
battery pack should be stored in dry conditions and a
temperature of less than 30°C. Higher temperatures and
excessive humidity may result in growth of mold on the
lenses and deterioration of the electronic components,
leading to instrument failure.
Battery operating hours tends to be reduced by continuous
use at extremely low temperatures.
