2. PRECAUTIONS
Charging Battery
• Be sure to charge the battery within the charging temperature range.
Charging temperature range: 0 to 40°C
Warranty policy for Battery
• Battery is an expendable item. The decline in retained capacity depending on the repeated charging/
discharging cycle is out of warranty.
Bluetooth Wireless Technology
•Bluetooth function may not be built in depending on telecommunications regulations of the country
or the area where the instrument is purchased. Contact your local dealer for the details.
Telescope
• Aiming the telescope at the sun will cause internal damage to the instrument. Use the solar filter
when observing the sun.
C"25. OPPTIONAL 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 tribrach. 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 handle of the instrument can be removed. When
operating the instrument with the handle attached, always
make sure that the handle is securely fixed to the
instrument body with the handle locks.
Precautions concerning water and dust resistance
The instrument 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 instrument 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 dealer.

5
2. PRECAUTIONS
• Do not press the speaker / luminance sensor / microphone 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 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.
The Tribrach
• Always use the tribrach provided. During a traverse observation, it is recommended to use the same
type of tribrach for the target as well for accurate observations.
Backing up data
• Data should be backed up (transferred to an external device etc.) on a regular basis to prevent data
loss.
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 instrument 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 instrument 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.
