4. PRODUCT OUTLINE
• Bluetooth/Wireless LAN function may not be built in depending on telecommunications regulations of the
country or the area where the instrument is purchased. Contact your local dealer for the details.
• 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.
"42. REGULATIONS"
• 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/Wireless LAN
Bluetooth/Wireless LAN communication with the GM uses the 2.4GHz 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/IEEE802.11n standard wireless LAN devices (When using Bluetooth function)
• The above devices use the same frequency band as Bluetooth communications. As a result, using the GM
within proximity to the above devices may result in interference causing communication failure or reduction
of transmission speed.
• Bluetooth devices (when Wireless LAN function)
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 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.
When using Bluetooth function in proximity to IEEE802.11b/IEEE802.11g/IEEE802.11n standard
wireless LAN devices, turn off all wireless LAN devices not being used and vice versa.
• 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 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.
