2. PRECAUTIONS
Telescope
• Aiming the telescope at the sun will cause internal damage to the instrument. Use the solar filter
when observing the sun.
C"25. Optional accessories"
Tribrach Clamp and Handle
• 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 tribrach.
• The FX handle can be removed. When operating the FX
with the handle attached, always make sure that the handle
is securely fixed to the FX body with the handle locks.
Precautions concerning water and dust resistance
FX conforms to IP65 specifications for waterproofing and dust resistance when battery cover,
connector cap and the external interface hatch and are closed.
• Be sure to correctly attach the connector caps to protect the FX from moisture and dust particles
when the connector is not in use.
• Make sure that moisture or dust particles do not come in contact with the terminal or connectors.
Operating the instrument with moisture or dust on the terminal or connectors 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.
• 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.
• 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.
The Lithium Battery
• The lithium battery is used to maintain the FX 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
Vertical and horizontal clamps
• Always fully release the vertical/horizontal clamps when rotating the instrument or telescope.
Rotationg with clamp(s) partially applied may adversely affect accuracy.
Backing up data
• Data should be backed up (transferred 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 an external battery (optional
accessory). 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.
Other precautions
• Never place the instrument directly on the ground. Sand or dust may cause damage to the screw
holes or the centering screw on the base plate.
• Do not perform vertical rotation of the telescope when using the lens hood, diagonal eyepiece, or
solar filter. Such accessories may strike the FX causing damage.
• Protect the instrument from heavy shocks or vibration.
• Protect the instrument from rain or drizzle with an umbrella or waterproof cover.
• Never carry the instrument on the tripod to another site.
• Turn the power off before removing the battery.
• Remove the battery before placing the FX in its case.
• Make sure that the instrument and the protective lining of the carrying case are dry before closing the
case. The case is hermetically sealed and if moisture is trapped inside, the instrument could rust.
• 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.
