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.
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:

the following points:
• The data connection works best when the communicator is in a stationary
position. Attempting wireless data communication while in a moving vehicle is
not recommended. Fax transmission is more easily impaired than data or short
message transmission.

• Do not place the communicator on a metal surface.
• Check that the signal strength on the communicator display is sufficient.
• Check that the signal strength on the communicator display is sufficient.
Moving the communicator within a room, especially towards a window, may
result in a stronger signal. If signals are not strong enough to support a voice
call, data connection should not be attempted until you can find a location with
better signal reception.

Note: When the antenna is up, the signal is stronger.
