Noise is heard during a call

This may be due to poor Signal Strength or the
unsuitable location of the CellRoute-GSM. It is
recommended that the CellRoute-GSM is positioned
a minimum of 1 metre from any other telephones
and other electronic devices.

Reception is poor

The CellRoute-GSM comes with a built-in antenna.
However, if you are experiencing problems with
poor reception, check that you are getting adequate
Signal Strength. This can be achieved by moving
the CellRoute-GSM to another location, - for
example, closer to a window or higher up in the
building.
In some locations your coverage area may require
a higher gain antenna for optimal call clarity and
performance. (Refer to page 8 "Connecting an
External Antenna"). For advice on external antennae
that can be connected to the CellRoute-GSM
contact your service provider.
