6. Can other electrical devices cause interference with Bluetooth?
Bluetooth technology employs a technique called frequency hopping to constantly change
the frequency at which it sends data, reducing interference with wireless devices like
wireless LAN’s, cordless landline phones. Noise Interference can occur if the Bluetooth
device is used in close proximity with microwave. Check if there are any such devices in the
surroundings, and if so keep the distance between the X3 micro 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.
7. If I cup my hand over a Bluetooth device the signal strength and quality suffers.
Why does this happen?
Bluetooth signals are radio waves and so do not need line of sight to operate. But, radio
waves cannot travel through water and as the human body is made up of mostly water they
cannot travel through it. And so, your hand will create a barrier causing slight interference
and a loss of signal quality.
8. What Bluetooth mobile phones can use the X3 micro headset?
To use the X3 the phone must support either Headset or Handsfree Bluetooth profiles.
Some devices may only support data transmissions and not audio. E.g. Nokia 7650
