Precautions - Sokkia CX 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
tribrachs. 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 tribrachs.
Precautions concerning water and dust resistance
CX conforms to IP66 specifications for waterproofing and dust resistance when
the battery cover and external interface hatch are closed and connector caps are
attached correctly.
• Be sure to close the battery cover and external interface hatch, and correctly
attach the connector caps to protect the CX 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.
• Do not press the speaker hole using something with a pointed tip. Doing so will
damage an internal waterproof sheet, resulting in a degraded waterproof
property.
• If there is a crack or deformation in the rubber packing for the battery cover or
external interface hatch, stop using and replace the packing.
• To retain the waterproof property, it is recommended that you replace the rubber
packing once every two years. To replace the packing, contact your local sales
representative.
The Lithium Battery
• The lithium battery is used to maintain the CX Calendar & Clock function. It can
back up data for approximately 5 years of normal use and storage (Temperature
= 20°, humidity = about 50%), but its lifetime may be shorter depending on
circumstances.
