Instruction manual

4. PRODUCT OUTLINE

• 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.

C"28. 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

Bluetooth communication with the OS 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

OS 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 OS 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 OS 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 OS in proximity to televisions and radios.
