Bluetooth
1. Is it safe to use Bluetooth devices, I have heard they can allow unauthorized
connections?
For Bluetooth security reasons, once 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 your device. (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 BlueSonic if they are in range?
No, the BlueSonic can only connect to previously paired devices that have been properly
authenticated. The Pairing procedure creates an encrypted key known only to the two
devices paired.
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 in 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 BlueSonic. 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 BlueSonic and still remain connected?
The BlueSonic will remain connected within a range of 10 meters (30ft). Sound quality may
start to deteriorate after approximately 7 meters depending on your environment.
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 such as
wireless LAN’s and cordless landline phones for example. 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 BlueSonic and
