2. PRECAUTIONS
Precautions regarding transmission
● For best results
• When using in conjunction with a total station, perform communication within a line-of-sight distance
of approximately 300m. The usable range becomes shorter when obstacles block the line of sight,
or devices other than total stations, such as PDAs or computers, are used. Wood, glass and plastic
will not impede communication but the usable range becomes shorter. Moreover, wood, glass and
plastic containing metal frames, plates, foil and other heat shielding elements as well as coatings
containing metallic powders may adversely affect Bluetooth communication and concrete,
reinforced concrete, and metal will render it impossible.
• Use a vinyl or plastic cover to protect the instrument from rain and moisture. Metallic materials
should not be used.
• The direction of the Bluetooth antenna can have adverse effects upon usable range. For best
results make sure that the antennas of both the Remote Controller and the companion device are
pointing towards one another.
● Reduced range due to atmospheric conditions
The radio waves used by the Remote Controller may be absorbed or scattered by rain, fog, and
moisture from the human body with the limit of usable range becoming lower as a result. Similarly,
usable range may also shorten when performing communication in wooded areas. Moreover, as
wireless devices lose signal strength when close to the ground, perform communication at as high a
position as possible.
• TOPCON CORPORATION cannot guarantee full compatibility with all Bluetooth product on the
market.
