Please make sure all RF connectors are
tightened and cables and antennas are
connected. Powering up the unit with no
antenna attached might cause irreparable
damage to the amplifier.
2.6.1 Turn-On Procedure
Once you verify that the antennas are attached correctly, Connect AC/DC Adaptor on the bi-directional
amplifier’s DC IN connector. Then switch the ON / OFF switch to ON position. The Power indicator LED
should be green. Verify that none of the “ALARM” LEDs is illuminated. If an ALARM LED is lit, consult
the trouble shooting pages of this manual, or “2.6.2 Antenna Isolation and Alignment” section.
2.6.2 Antenna Isolation and Alignment
Good isolation between the two antennas is critical for the operation of the repeater system. This is not
an issue as long as the distance between the outside antennas and the inside antenna is at least 15 ft,
there is a wall between them, and the outside antenna is not pointed toward the inside antenna. TOP
SIGNAL 65 is equipped with an over drive protection circuit, which will also detect the isolation problem
between the antennas. This alarm is indicated by a blinking “ALARM” LED.
2.6.2.1 Antenna Alignment
If you are triggering the overdrive alarms at any point, try to increase the isolation between the antennas
by relocating the indoor antenna. The indoor antenna should be placed physically as far away from the
outdoor antenna as practical. If you are using directional antennas, try to find a location for the indoor
antenna where it can cover the needed area and oriented back to back with respect to the outdoor
antenna.
<Optional>
At this point, you may want to optimize the outdoor antenna. If the outdoor antenna can be turned in
place, try turning it from one end to the other by one inch increment. At each point, observe the signal
strength in indoor coverage area. When you find the best direction for the outdoor antenna, tie down
everything and secure the antenna.
Caution!
