    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.
  • Page 11 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. Speaker The Lithium Battery • The lithium battery is used to maintain the OS 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.
  • Page 12 2. PRECAUTIONS 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.
  • Page 13 2. PRECAUTIONS • Store the instrument 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.
