Step 1. Choose an Antenna Location
Your Phonecell SX3 receives operating commands from the cel-
lular network and relies upon signal strength for proper opera-
tion. Therefore, finding an antenna location with good signal
strength is critical for call quality.

:
·· Locate the antenna above ground and as close
to windows (or exterior walls) as possible see
Fig. 1.
·· Try to install the antenna in an uninhabited area
(i.e. closets, attics, etc.) to ensure a minimum
separation of 16 inches (40 cm) between the
antenna and the inhabitants.
·· In low signal areas, the antenna should be
mounted on the buildings exterior see Fig. 2.
·· High-gain (Yagi) antennas must be directed
toward your service providers nearest cellular
tower.
·· Spike antennas must be pointed upward.
·· Keep antenna cable as short as possible long
cable runs affect call quality.
·· Never splice antenna cable.

direct the antenna toward the nearest cell tower of your service provider.
