Precautions
On Bluetooth communication
Bluetooth wireless technology operates within a range of about 10 meters (30 feet).
Maximum communication range may vary depending on obstacles (human body, metal, wall, etc.) or
electromagnetic environment.
The antenna is built into the unit as illustrated in the dotted line. The sensitivity of the Bluetooth
communication will improve by turning the direction of the built-in antenna to the connected
Bluetooth device.
The communication distance shortens when the obstacles are between the antenna of the connected
device and this unit.

The following conditions may affect the sensitivity of Bluetooth communication.
– There is an obstacle such as a human body, 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 resulting in communication speed deterioration, noise, or invalid
connection if this unit is used near a wireless LAN device. In such a case, perform the following.
– Use this unit at least 10 m (30 ft) away from the wireless LAN device.
– If this unit is used within 10 m (30 ft) 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 a petrol station
– near automatic doors or a fire alarm
This unit supports security capabilities that comply with the Bluetooth standard to provide a secure
connection when the Bluetooth wireless technology is used, but security may not be enough
depending on the setting. Be careful when communicating using Bluetooth wireless technology.
We do not take any responsibility for the leakage of information during Bluetooth communication.
Connection with all Bluetooth devices cannot be guaranteed.
– A device featuring Bluetooth function is required to conform to the Bluetooth standard specified by
Bluetooth SIG, Inc. and be authenticated.
– Even if the connected device conforms to the above mentioned Bluetooth standard, some devices
may not be connected or work correctly, depending on the features or specifications of the device.
– While talking on the phone hands free, noise may occur, depending on the device or
communication environment.
Depending on the device to be connected, it may require some time to start communication.
On charging the unit
This unit can be charged using USB only. Personal computer with USB port, or USB Charging AC
Power Adaptor AC-UD10 (sold separately) is required for charging.
