Note: As with any other radio transmitting device, do not
touch the antenna unnecessarily when the device is
switched on. Contact with the antenna affects call
quality and may cause the device to operate at a higher power level
than otherwise needed. Avoiding contact with the antenna area
when operating the device optimises the antenna performance and
the battery life.
