like wireless LAN’s and cordless landline phones. However,
noise interference can occur if the Bluetooth device is used
in close proximity with a microwave. Check if there are
any such devices in the surroundings, and if so keep the
distance between the Supertooth 3 and such devices to at
least 5 - 10m. Usually, any interference will only cause a
slight crackling sound. The frequency of Bluetooth is much
higher than that of radio station bands.
8. If I cup my hand over a Bluetooth device the signal
strength and quality suffers. Why does this happen?
Bluetooth signals are radio waves, hence do not require a
direct line of sight to operate. However, radio waves cannot
travel through water and as the human body is made up of
mostly water they cannot travel through it. Therefore, your
hand will create a barrier causing slight interference and a
loss of signal quality.
9. What Bluetooth mobile phones can I use with the
Supertooth
3?
To use the Supertooth 3 the phone must support either
headset or hands free Bluetooth profiles. Some devices may
only support data transmissions and not audio.
10. What is the difference between Bluetooth V1.2
and
V2.0?
V2.0 is the current version of Bluetooth with Enhanced Data
Rate (EDR) technology, with data transfer rates of up to
3Mbps compared with 1Mbps in V1.2.
Note: All BlueAnt products are forward and backward
compatible (Our V1.2 products can be used with V2.0 phones
and our V2.0 products can be used with V1.2 phones)
