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.
