 LEDs 2 to 9 (green) indicate the quality of the received signal. The higher the
number of LEDs illuminating, the better the quality of the received signal.
 If all LEDs, including LED 10 (red) are on, the received signal strength is too
high. This must be avoided, preferably by up-tilting the antenna. As a rule of
thumb, if the SU is located at a distance of less than 300 meters from the Base
Station, it is recommended to up-tilt the antenna by approximately 10° to 15°.
1 Point the antenna toward the general direction of the Base Station.
2 Connect the SAU to the ODU.
3 Verify that the PWR (power) indication on the SAU is on.
4 Verify that the WLNK (LED 1) indicator is on, indicating that the unit is
synchronized with the Base Station. If the SU is not synchronized with the
Base Station, ensure that all parameters are configured properly. If the unit is
still not synchronized with the Base Station, improve the quality of the link by
changing the direction of the antenna or by placing the antenna at a higher
point or in an alternate location.
5 Rotate (and/or tilt if applicable) the ODU/antenna until the maximum link
quality reading is achieved. If you encounter prolonged difficulty in achieving
the expected link quality, try to improve the reception quality by placing the
antenna at a higher point or in an alternate location.
6 Secure the ODU/antenna firmly to the pole.
To align the antenna:
NOTE
Ensure that the front of the antenna is always facing the Base Station. However, in certain
conditions, such as when the line of sight to the Base Station is hampered, better reception may be
achieved using a reflected signal. In this case, the antenna is not necessarily directed toward the
Base Station.
