Installation Guide
WARNING!
Radiation hazard – risk of Radio Frequency (RF) exposure. This subscriber unit is compliant with the
requirements set forth in FCC CFR 47, section 1.1307, addressing Radio Frequency (RF) exposure from
radio frequency base stations, as defined in
Engineering_Technology/Documents/bulletins/oet65/oet65.pdf]. The emitted radiation should be as
little as possible. To achieve minimum RF exposure, install the subscriber unit 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 subscriber unit or other operations which require RF
exposure, the exposure should be minimized in time and according to the regulations set forth by the
country of installation or the Federal Communications Commission (FCC).
WARNING!
The subscriber unit must be placed at a distance of at least 20 cm (8 in) from all persons during normal
operation. The antennas used for this product must not be located or operating in conjunction with any
other antenna or transmitter, except in accordance with FCC multi-transmitter evaluation procedures.
IMPORTANT!
During antenna installation, observe the following:
• Always install the antenna at least 40 cm (16 in) from people and public areas.
• Antenna must be in a fixed position.
• 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 subscriber unit 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 subscriber unit
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 general rule, if the subscriber unit is located at a
distance of less than 300 m (984 ft) from the base station, it is recommended to tilt the antenna
upwards by approximately 10 to 15°.
• After the antenna is installed, do not change the antenna position.
1.
Mount the antenna to a pole or wall in an area that provides good signal coverage and is away from any
signal noise emanating from other communications equipment.
2.
Position the antenna towards the general direction of the designated base station.
WARNING!
Fire hazard – risk of serious personal injury and/or damage to equipment. To reduce the risk of fire,
use only 26 AWG or larger telecommunication line cord between indoor and outdoor devices.
3.
Using shielded coaxial cables, connect the antenna to the lightning protector. Make sure the cables are
routed away from any noise sources, such as Switch-Mode Power Supplies (SMPS).
