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.

2. PRECAUTIONS
6
Vertical and horizontal clamps
• Always fully release the vertical/horizontal clamps when rotating the instrument
or telescope. Rotating with clamp(s) partially applied may adversely affect
accuracy.
Backing up data
• Data should be backed up (transfered to an external device etc.) on a regular
basis to prevent data loss.
Use under low temperatures (Low Temperature Model only)
• Do not use force to scrape off frost from the lens or display unit screen. Frost is
an abrasive material and may scratch the instrument.
• If ice or snow attaches itself to the unit, wipe it off with a soft cloth, or place the
unit in a warm room until the ice melts, and then wipe off the meltwater.
Operating the unit with ice or snow attached may cause operation errors to
occur.
• Wipe off condensation with a soft cloth before using the instrument. Not doing
so may cause operation errors to occur.
• The working duration of battery BDC70 will rapidly decline in cold temperatures.
When using the instrument in temperatures around -30°C, we recommend that
you use external battery BDC60 or BDC61 (optional accessories) and
dedicated cables EDC119. However, if you unavoidably must use battery
BDC70 for measurements in temperatures around -30°C, recharge the battery
in a warm room and keep the battery in a warm place such as your pocket until
it is used. (Working duration of battery will change with environmental
conditions.)
• The lens cap and lens hood may become difficult to attach in low temperatures.
Keep them in a warm place such as a pocket until attached.
• If the unit is carried between locations that have extreme temperature
differences, protect the unit from rapid temperature change by placing it in the
carrying case.
• Please use the tribrach supplied as standard. If a different tribrach is used,
angle measurement errors may occur.

2. PRECAUTIONS
Other precautions
• Close the external interface hatch before starting measurement. Otherwise,
ambient light entering the USB port may adversely affect measurement results.
• If the CX is moved from a warm place to an extremely cold place, internal parts
may contract and make the keys difficult to operate. This is caused by cold air
trapped inside the hermetically sealed casing. If the keys do not depress, open
the battery cover to resume normal functionality. To prevent the keys from
becoming stiff, remove the connector caps before moving the CX to a cold
place.
• Never place the CX directly on the ground. Sand or dust may cause damage to
the screw holes or the centering screw on the base plate.
• Do not aim the telescope directly at the sun. Also, attach the lens cap to the
telescope when not in use. Use the Solar filter to avoid causing internal
damage to the instrument when observing the sun.
C"36.2 Optional accessories"
• Protect the CX from heavy shocks or vibration.
• Never carry the CX on the tripod to another site.
• Turn the power off before removing the battery.
• When placing the CX in its case, first remove its battery and place it in the case
in accordance with the layout plan.
• Consult your local dealer before using the instrument under special conditions
such as long periods of continuous use or high levels of humidity. In general,
special conditions are treated as being outside the scope of the product
warranty.
Maintenance
• Always clean the instrument before returning it to the case. The lens requires
special care. First, dust it off with the lens brush to remove tiny particles. Then,
after providing a little condensation by breathing on the lens, wipe it with the
wiping cloth.
• If the display unit is dirty, carefully wipe it with a soft, dry cloth. To clean other
parts of the instrument or the carrying case, lightly moisten a soft cloth in a mild
detergent solution. Wring out excess water until the cloth is slightly damp, then
carefully wipe the surface of the unit. Do not use any alkaline cleaning solutions,
alcohol, or any other organic solvents, on the instrument or display unit.
• Store the CX in a dry room where the temperature remains fairly constant.
• Check the tripod for loose fit and loose screws.
• If any trouble is found on the rotatable portion, screws or optical parts (e.g.
lens), contact your local dealer.

2. PRECAUTIONS
8
• When the instrument is not used for a long time, check it at least once every 3
months.
C"35. CHECKS AND ADJUSTMENTS"
• When removing the CX from the carrying case, never pull it out by force. The
empty carrying case should be closed to protect it from moisture.
• Check the CX for proper adjustment periodically to maintain the instrument
accuracy.
