on a frequency of 2.45 GHz. This frequency band is also internationally used for industrial, scientific and medical devices (ISM). The low power limits the communication range to about 10 meters (30 feet). However the communication range may be reduced due to electromagnetic environment and obstacles found within the 10 meters radius. Below conditions cause loss of signal quality and communication range.
- There are obstacles such as human bodies or metal objects.
- Other devices using the same frequency band are in use (eg: cordless phones, microwave oven, medical devices and wireless LAN device).
- The unit is placed on a steel or other metal cabinet.
When this unit is placed too near a Wireless LAN device or microwave, noise interference may occur, causing crackling sound. It may also reduce the communication speed and cause invalid connection. If these happen, do the following:
- Place the unit at least 10 meters away from the Wireless LAN device.
- Turn off the Wireless LAN device if it is less than 10 meters away.
- Place the unit closer to the

About Bluetooth technology
Bluetooth wireless technology is a short-range radio technology that enables wireless communication between various types of digital devices, such as mobile phone or computer. It operates within a range of about 10 meters (30 feet) without the hassle of having to use cables to connect these devices. Since the Bluetooth technology does not require line of sight between the communicating devices, it is not necessary to line up the transmitting device and the receiver, as in the case of infra red technology.
Communication System and Bluetooth Profile of this unit
There are many available Bluetooth Profiles describing the basic communication methods, specific functions and uses, to enable communication between devices.
This unit supports the following: Communication System: Bluetooth Specification version 1.2 Bluetooth Profile : A2DP (Advanced Audio Distribution Profile) A2DP enables audio streaming from an A2DP equipped Bluetooth stereo audio source device (eg mobile phone) to this unit. By converting wireless stereo audio signal to analogue audio signal, you can enjoy listening to the sound through this speaker system.

Notes:
If this unit or the source device is turned off before Bluetooth
connection is completed, pairing will not be completed and the pairing information will not be memorised. Repeat step 1 onwards to start pairing again.
To pair with other devices, repeat steps 1 - 5 for each device.
This unit can be paired to a maximum of 8 devices. If subsequent device is paired, the oldest device paired, will be deleted from the list.
Once a device is ousted or deleted from the pairing list, the
pairing information for the device is also deleted. To listen to the sound from the device again, it needs to be re-paired. Perform steps 1 - 5 to pair the device again.
Passcode of this unit is fixed to “0000” and can only be paired
with Bluetooth source device whose passcode is also “0000”.
