2. PRECAUTIONS
When using
Bluetooth
function in proximity to IEEE802.11b or IEEE802.11g standard wireless LAN
devices, turn off all devices not being used.
• Interference may result, causing transmission speed to slow or even disrupting the connection
completely. Turn off all devices not being used and vice versa.
Refrain from using the TP-L6W in proximity to televisions and radios.
• Televisions and radios use a different frequency band to
Bluetooth
communications.
However, even if the TP-L6W is used within proximity to the above equipment with no adverse effects
with regard to
Bluetooth
communication, moving a
Bluetooth
compatible device (including the TP-
L6W) 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
wireless 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 TP-L6W 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.
Other precautions
• Protect the instrument from heavy shocks or vibration.
• When setting up the instrument, position it so the bubble in the digital level vial on the display is in the center
position.
• When you remove the instrument from the carrying case, be sure to open the cover of the case after laying
the case down, right side up.
• 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.
• Physical reflection and refraction may occur under hot weather conditions or in a small pipe diameter due to
its temperature or moisture conditions, which could interfere with the precision or available range of the
instrument. To minimize the effect of these conditions please take the following precautions.
1) Place the pipe hot side (heated by sunlight etc.) down.
2) Do not apply an excessive amount of "pipe adhesive" to the pipe joints.
3) Immediately back fill the trench as pipe work is finished.
If it is difficult to follow the instructions noted above, please use a blower (commercially-available) or place
the instrument on the pipe before performing the operation.
User
• Wear the required protectors (safety shoes, helmet, etc.) when operating.
