•
Bluetooth
communication is only possible with instruments incorporating the
Bluetooth
module.
• 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.
• TOPCON CORPORATION 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 DS 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
DS 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.
I
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 and take measures to prevent further
interference (e.g. connect using an interface cable).
• In the case that the instrument causes radio interference with portable specified low-power radio
equipment, contact your local dealer.
I
When using the DS 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.
I
Do not use the DS 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.
I
Refrain from using the DS in proximity to televisions and radios.
