BLUETOOTH SETUP
Bluetooth connectivity performance may vary with brand and model of the connected
device. For best performance, please connect newer Bluetooth devices incorporating
Bluetooth 2.1 and using the latest firmware update available from the device vendor.
Compatibility with all devices and media types is not guaranteed.
Bluetooth performance considerations ensure all Bluetooth devices within 30 feet have
Bluetooth transmission disabled. The presence of other functioning Bluetooth devices
during connection may lead to operational difficulties. Bluetooth is a short-range radio
communication standard. The Bluetooth transmitter and receiver hardware in this unit
has an approximate operational range of 30 feet in open space. Generally Bluetooth
devices can communicate with each other clearly within a regular sized room or office.
Operation between different rooms will depend on the construction of the room.
It is important to recognize the fact that Bluetooth communication range may be
substantially reduced if the signal passes through a solid object. Human bodies, brick
and concrete walls, and heavy furniture or bookcases will reduce the operational range
of your Bluetooth devices. Glass, dry-wall or wood paneled walls and office partitions
may have a less severe but noticeable effect. You should position your Bluetooth
devices closer to each other if you observe communication difficulties.
Stereo music connection to your smart phones (such as Android® smarphones,
Iphones®, Windowsphone® etc…) connection or PC tablet, multi-media player etc… all
devices having Bluetooth function, you will need some familiarity with the Bluetooth
functions of your Bluetooth device. As each device operates slightly differently, please
familiarize yourself with the Bluetooth capabilities of your device before connecting.
