■ Antenna
Your device has an internal antenna located at the bottom of the device.
Use the phone with the slide open to avoid contact with the antenna area.
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 optimizes the antenna performance and the
battery life.
