(Auto rotation)
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.
About operation when the power is turned ON/OFF
This instrument operates as shown below and performs auto leveling/auto rotation when the power of
the instrument is turned ON or OFF. Do not touch the instrument during operation. Doing so may
cause injury.
Precautions concerning water and dust resistance
Dustproof and waterproof performance of the instrument comply with IP65. Please read the following
carefully before using.

• 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.

• 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.
Maintenance
• Wipe off moisture completely if the instrument gets wet during survey work.
• 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.
• 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.
• When the instrument is not used for a long time, check it at least once every 3 months.
• Every 4,000 to 5,000 hours operation in total, change grease of driving parts. Contact your local
dealer for the maintenance.
