• Televisions and radios use a different frequency band to Bluetooth communications.
However, even if the PS is used within proximity to the above equipment with no adverse effects
with regard to Bluetooth communication, moving a Bluetooth compatible device (including the
PS) closer to said equipment may result in electronic noise in sound or images, adversely
affecting the performance of televisions and radios.
Precautions regarding transmission
I 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.
• The direction of the Bluetooth antenna can have adverse effects upon usable range.
I Reduced range due to atmospheric conditions
• The radio waves used by the PS 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.
