viii
Do not use the GM in proximity to microwaves.
• Microwave ovens can cause significant interference resulting in communication failure. Perform
communication at a distance of 3 m or more from microwave ovens.
Refrain from using the GM in proximity to televisions and radios.
• Televisions and radios use a different frequency band to
Bluetooth
communications. However, even if the
GM is used within proximity to the above equipment with no adverse effects with regard to
Bluetooth
communication, moving a
Bluetooth
compatible device (including the GM) closer to said equipment may
result in electronic noise in sound or images, adversely affecting the performance of televisions and
radios.
Precautions regarding transmission
For best results
• The usable range becomes shorter when obstacles block the line of sight, or devices 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.
Reduced range due to atmospheric conditions
• The radio waves used by the GM 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
products on the market.
