The T39 has built-in
Bluetooth
wireless technology. Short-range radio links operate in a glo-
bally available 2.4 GHz radio frequency band, and ensures fast and secure communications up
to a range of 10 metres (typically) between devices. Please note that in countries where the use
of
Bluetooth
wireless technology is not allowed, you must ensure that the
Bluetooth
function is
set to off. Contact the Ericsson representative to check if the use of
Bluetooth
wireless technol-
ogy is restricted in your country.
Bluetooth
wireless technology is designed to be fully functional even in very noisy radio fre-
quency environments and it provides a high transmission rate. All data transfer is protected by
advanced error-correction methods that ensure a high level of data security.
Bluetooth
wireless technology facilitates instant connections which are maintained even when
the devices are not within line of sight.
Bluetooth
wireless technology facilitates high-quality
voice transmissions, even under severe conditions. For example, you can connect your headset
to your mobile phone to keep your hands free for more important tasks.
Ericsson is a founding partner of the
Bluetooth
Special Interest Group (SIG).
