B. Bluetooth
1.Is it safe to use Bluetooth devices, I have heard they can allow unauthorized connections?
For Bluetooth security reasons, after you have set up your bluetooth devices we recommend turning OFF the visibility option in the Bluetooth Menu of your phone so that other Bluetooth users cannot see the your phone. (This only applies to a few mainly older Bluetooth enabled phones as most new phones have better security.)
2.Can somebody else take control of my V12 if they are in range?
No, the V12 can only connect to previously paired devices that have been authenticated.
3.What is the difference between Handsfree and Headset Bluetooth Profiles? Handsfree Profile allows for extra features to be used with a mobile phone. Voice Dial, redial, call transfer are some that are included in Handsfree but not Headset. Handsfree also allows for a slightly better call quality.
4.How do I know if my devices are connected?
When Bluetooth is turned ON on your phone you may see a Bluetooth symbol appear on your main screen that changes slightly (colours invert or arrows appear) when connected to the V12. Some phones show a Headset or Car symbol to notify you that the devices are connected.
5.How far can my mobile be from the V12 and still remain connected?
The V12 will remain connected within a range of 10 meters (30 ft). Sound quality may start to deteriorate after about 7 meters depending on your environment and if obstacles are present.
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 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. And so, 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.
