Precautions concerning
Bluetooth
wireless technology
• 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.
C
"13. REGULATIONS"
• Sokkia Topcon Co., Ltd. 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 RC-Controller 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 standard wireless LAN devices
The above devices use the same frequency band as
Bluetooth
communications. As a result, using the
RC-Controller 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.
• In the case that the instrument causes radio interference with portable specified low-power radio
equipment, move away from said equipment and try again. If the problem persists contact your local
dealer.
●
When using the RC-Controller 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.
●
Do not use the RC-Controller in proximity to microwaves.
• Microwave ovens can cause significant interference resulting in communication failure. Perform
communication at a distance of 3m or more from microwave ovens.
●
Refrain from using the RC-Controller in proximity to televisions and radios.
• Televisions and radios use a different frequency band to
Bluetooth
communications.
However, even if the RC-Controller is used within proximity to the above equipment with no adverse
effects with regard to
Bluetooth
communication, moving a
Bluetooth
-compatible device (including
