Introduction
Electrostatic discharge
A discharge of static electricity from a finger or a conductor may cause erroneous
functions in electric devices. The discharge may result in distorted display and
unstable software operation. Wireless connections may become unreliable, data
may become corrupted, and the transmission halted. In this case you need to end
the existing call (if any), close the cover and switch off the phone (if on) and
remove the battery. Then replace the battery and establish a new wireless
connection.
Dead spots and dropouts
Dead spots are areas where radio signals cannot be received. Dropouts occur when
the phone user passes through an area where the radio signal is blocked or reduced
by geographical features or large structures.
Signal impairment
Distance and obstacles can cause signals to become out-of-phase. They can also
cause reflected signals. Both situations result in a loss of signal strength.
Low signal strength
Due to either distance or obstacles, the radio signal strength from a cell site may
not be strong or stable enough to provide a reliable data connection for
communication. Therefore, to ensure the best possible communication, remember
the following points:
