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, thus reducing interference with wireless devices like
wireless LAN’s, 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 V12 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. Therefore, your hand will create a barrier causing slight
interference and a loss of signal quality.
8. What Bluetooth devices can use a Bluetooth headset?
To use the V12 the device must support either headset or Handsfree Bluetooth Profiles.
Some devices may only support data transmissions and not audio.
