Repeater Terminology
Here are a few terms that you’ll need to be familiar with in order to use
this instruction manual. Please read carefully.
Directional Outdoor Antenna
This is the antenna that is used to collect and route signal to the cell
phone tower.
Monopole Antenna
This smaller antenna is attached to the top of the Clear Voice amplier
and rebroadcasts the signal inside your home or oce. Other types of
rebroadcast antennas are also available and can oer a better in-door
coverage. Please see accessory section for futher information.
Oscillation (also feedback)
If your repeater is set up incorrectly, oscillation may occur. Oscillation is
also known as feedback. Oscillation occurs when there is not enough
isolation between the directional outdoor antenna and the repeater
unit. A lack of isolation means that the cellular signal being rebroadcast
by the repeater is recaptured by the directional antenna and reamplied,
causing a feedback loop that prevents the repeater from working
correctly. To improve the isolation and prevent this from happening, the
amplier unit and directional antenna must be well separated, and the
directional antenna must be kept facing away from the amplier unit.
Auto Shut-O
When oscillation occurs, the repeater “auto shut-o” feature is triggered
to prevent harm to the repeater and the cellular network. The red LED
will turn “ON” if the input signal is too strong. This will not normally
happen unless there is insucient isolation. The repeater will have to be
restarted: You can manually restart the repeater by disconnecting and
reconnecting the AC adapter.
Automatic Level Control (ALC)
Our Clear Voice ampliers have ALC built in. This feature automatically
adjusts the signal output level to prevent oscillation from occurring in
case signal conditions change after the repeater has been installed.
