Bluetooth wireless technology operates within a range of about 10 m (about 33 feet). Connecting two devices is common, but some devices can be connected to multiple devices at the same time. • You do not need to use a cable for connection since Bluetooth technology is a wireless technology, neither is it necessary for the devices to face one another, such is the case with infrared technology. For example, you can use such a device in a bag or pocket. • Bluetooth technology is an international standard supported by millions of companies all over the world, and employed by various companies worldwide. On Bluetooth communication • Bluetooth wireless technology operates within a range of about 10 m. Maximum communication range may vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment. • The following conditions may affect the sensitivity of Bluetooth communication. - There is an obstacle such as a person, metal, or wall between this unit and Bluetooth device. - A device using 2.4 GHz frequency, such as a wireless LAN device, cordless telephone, or microwave oven, is in use near this unit. • Because Bluetooth devices and wireless LAN (IEEE802.11b/g) use the same frequency, microwave interference may occur and result in communication speed deterioration, noise, or invalid connection if this unit is used near a wireless LAN device. In such as case, perform the following. - Use this unit at least 10 m away from the wireless LAN device. - If this unit is used within 10 m of a wireless LAN device, turn off the wireless LAN device. - Install this unit and Bluetooth device as near to each other as possible. • Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off this unit and other Bluetooth devices in the following locations, as it may cause an accident. - where inflammable gas is present, in a hospital, train, airplane, or petrol station - near automatic doors or a fire alarm continue to next page t 25
