previously paired devices that have been authorised. The

the two devices paired.
4. How do I know if my devices are connected?
When Bluetooth is turned ON in your phone you will see
a Bluetooth symbol appear on your main screen that
changes slightly (colours invert or arrows appear) when
connected to the M1 Stereo Speakers. Some phones
show a Headset symbol to notify you that the devices are
connected.
5. How far can my mobile be from the M1 Stereo
Speakers and still remain connected?
The M1 Stereo Speakers will remain connected within
a range of 10 metres (30 ft). Sound quality may start
to deteriorate after about 7 metres 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, thus reducing interference with wireless
devices like wireless LAN ’s and cordless landline phones.
However, 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 M1 Stereo Speakers 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
