Precautions - Sokkia 130R Series Operator's Manual

2. PRECAUTIONS

Tribrach Clamp
• When the instrument is shipped, the
tribrach clamp is held firmly in place
with a locking screw to prevent the
instrument from shifting on the
levelling base. Before using the
instrument the first time, loosen this
screw with a screwdriver. And before
transporting it, tighten the locking
screw to fasten the tribrach clamp in
place so that it will not shift on the
levelling base.
Precautions concerning water and dust resistance
SET conforms to IP64 specifications for waterproofing and dust resistance when
the battery cover is closed and connector caps are attached correctly.
• Be sure to close the battery cover and correctly attach the connector caps to
protect the SET from moisture and dust particles.
• Make sure that moisture or dust particles do not come in contact with the inside
of the battery cover, terminal or connectors.
Contact with these parts may cause damage to the instrument.
• Make sure that the inside of the carrying case and the instrument are dry before
closing the case. If moisture is trapped inside the case, it may cause the
instrument to rust.
The Lithium Battery
The lithium battery, a backup battery which retains data in the internal memory of
the SET, can back up data for approximately 5 years of normal use, but its lifetime
may be shorter depending on circumstances. Therefore be sure to replace the
lithium battery after the instrument has been used for 4 years. Ask your Sokkia
service center to replace the battery for you. When the lithium battery is replaced,
all stored data is cleared. If the voltage supplied by the lithium battery either
declines or is completely discharged, the message "Exchange sub bat." is
displayed. If the lithium battery completely fails, the data is entirely cleared. We
recommend that you store data you must retain to your computer.
