Installing the Antenna
8. Tighten the screws connecting the arm bracket to the device and mounting bracket. Make sure the screws
are torqued to 24 N·m (17.7 ft. lb.).
Section 2.2
Installing the Antenna
To install the antenna, do the following:
WARNING!
Radiation hazard – risk of Radio Frequency (RF) exposure. This base station is compliant with
the requirements set forth in CFR 47, section 1.1307, addressing Radio Frequency (RF) exposure
from radio frequency base stations, as defined in FCC OET Bulletin 65
transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet65/oet65.pdf]. The emitted
radiation should be as little as possible. To achieve minimum RF exposure, install the base station
when it is configured not to transmit and set it to operational mode remotely, rather than having a
technician enable transmission on-site. For maintenance of the base station, or other operations which
require RF exposure, the exposure should be minimized in time and according to the regulations set by
the FCC or the regulations relevant to the country of installation.
IMPORTANT!
During antenna installation, observe the following:
• Always install the antenna at least 0.39 m from people and public areas.
• Antenna must be in a fixed position.
• After it is installed, do not change the antenna position.
NOTE
The device is compliant with the requirements set forth in CFR 47, section 1.1307, addressing Radio
Frequency (RF) exposure from radio frequency devices as defined in OET Bulletin 65. The emitted
radiation should be as little as possible. To achieve minimum RF exposure, install the device when it
is configured not to transmit and set it to operational mode remotely, rather than enabling transmission
by the installer on-site. For maintenance of the device, or other operations which require RF exposure,
minimize the exposure time according to the regulations set by the FCC or the regulations relevant to
the country of installation.
IMPORTANT!
Make sure the front of the antenna is always facing the base station. In some conditions, such as when
the line of sight to the base station is impeded, better reception may be achieved using a reflected
signal. In this case, direct the antenna towards the reflecting object, rather than towards the base
station.
In some cases, the antenna may need to be tilted to make sure the level at which the device receives
transmissions from the base station (and vice versa) is not too high. When only the last RSSI LED is
on, this indicates saturation and the received signal level is too high. This must be avoided, preferably
by tilting the antenna upwards. As a rule of thumb, if the device is located at a distance of less than 300
meters from the base station, it is recommended to tilt the antenna upwards by approximately 10° to
15°.
1. Point the antenna towards the general direction of the designated base station.
2. Verify that power is applied to the device. The PWR LED should be ON.
