Bluetooth FAQ
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 X5 Stereo if they are in
range?
No, the X5 Stereo 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 (colors invert or
arrows appear) when connected to the X5 Stereo. 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 X5 Stereo and still remain
connected?
The X5 Stereo 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.
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 X5 Stereo 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
