Hints for Optimum Audio Transmission
z The wireless performance of Bluetooth devices
depends on the environment where it is used.
z Walls, partitions, doors, furniture etc can block
the path of transmitted radio signals thereby
resulting in shorter range and even sound
distortions.
z Likewise, the human body also affects the
performance and since the C2 is clipped onto
clothing and held close to the body, it is a good
practice not to cover the C2 or the host device
with hand.
