Installing the SOMAport 140 Where to put the SOMAport 140
Where to put the SOMAport 140
Put the SOMAport 140 where you can reach it easily and where you can
connect other devices to it with cables that do not exceed recommended
maximum cable lengths.
Do not place the SOMAport 140 near a computer monitor. Doing so can cause
interference.
Maximizing the signal strength
Like a radio receiver, the SOMAport 140 uses an antenna to receive radio
signals from a transmitting tower. However, the SOMAport 140 has an internal
antenna that is “smarter” than a typical radio antenna. You don’t have to aim
this antenna yourself. It is software-controlled and changes direction
automatically to maximize signal reception.
Recommendations
Though the SOMAport 140 internal antenna is self-aiming, you can take steps
to optimize the quality of the signal reception and performance of the
SOMAport 140.
n Allow at least 18 inches of space around the SOMAport 140.
n Avoid placing the SOMAport 140 close to certain electronic devices such as
n microwave ovens, cordless phones, and PCS phones.
n Place the SOMAport 140 as high up in your home or building as possible.
n Avoid putting it in the basement because the signal will be weakest there.
n Experiment with its exact placement and use the signal strength indicator to
n see if you can get a stronger signal.
n If you are having problems getting a strong signal, try placing the SOMAport
n 140 near a window.
WARNING: While this device is in operation, a separation distance of at least 20 centimeters (3.1 inches)
must be maintained between the radiating antenna and the body of all persons exposed to the transmitter in
order to meet the FCC RF exposure guidelines. No change to the antenna or device is permitted. Doing so
may result in in the installed system exceeding the RF exposure requirements. This device must not be
co-located or operating in conjunction with any other antenna or radio transmitter. Installers and
end-users must follow the installation instructions provided in this user guide.
