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 silicon cloth.
• If the display unit is dirty, carefully wipe it with a soft, dry cloth. To clean other parts of the instrument or the
carrying case, lightly moisten a soft cloth in a mild detergent solution. Wring out excess water until the cloth
is slightly damp, then carefully wipe the surface of the unit. Do not use any alkaline cleaning solutions,
alcohol, or any other organic solvents, on the instrument or display unit.
• Store the GM 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.
• When removing the GM from the carrying case, never pull it out by force. The empty carrying case should be
closed to protect it from moisture.
• Check the GM for proper adjustment periodically to maintain the instrument accuracy.
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.
• Use of this technology must be authorized according to telecommunications regulations of the country where
the instrument is being used. Contact your local dealer in advance.
• TOPCON CORPORATION is not liable for the content of any transmission nor any content related thereto.
When communicating important data, run tests beforehand to ascertain that communication is operating
normally.
• Do not divulge the content of any transmission to any third party.
Radio interference when using
Bluetooth
technology
Bluetooth
communication with the GM uses the 2.4 GHz frequency band. This is the same band used by the
devices described below.
• Industrial, scientific, and medical (ISM) equipment such as microwaves and pacemakers.
• portable premises radio equipment (license required) used in factory production lines etc.
• portable specified low-power radio equipment (license-exempt)
• IEEE802.11b/IEEE802.11g/IEEE802.11n standard wireless LAN devices
• The above devices use the same frequency band as
Bluetooth
communications. As a result, using the
GM within proximity to the above devices may result in interference causing communication failure or
reduction of transmission speed.
Although a radio station license is not required for this instrument, bear in mind the following points when using
Bluetooth
technology for communication.
Regarding portable premises radio equipment and portable specified low-power radio equipment:
• Before starting transmission, check that operation will not take place within the vicinity of portable
premises radio equipment or specified low-power radio equipment.
• In the case that the instrument causes radio interference with portable premises radio equipment,
terminate the connection immediately and take measures to prevent further interference (e.g. connect
using an interface cable).
• In the case that the instrument causes radio interference with portable specified low-power radio
equipment, contact your local dealer.
When using
Bluetooth
function in proximity to IEEE802.11b/IEEE802.11g/IEEE802.11n standard wireless
LAN devices, turn off all wireless LAN devices not being used.
• Interference may result, causing transmission speed to slow or even disrupting the connection
completely.
