58 CPE Installation and Pointing
Proprietary and Confidential
Once you tighten the nuts, the settings may change; consequently, the audio tones
might change. This is the expected normal mode of operation.
Fine Pointing
The process is completed by fine-tuning the dish position using the built-in tuning tool
until the strongest signal is obtained.
Fine pointing of the dish can be started once a Locked tone ( LockLowSNR ,
LockMedSNR , LockMaxSNR ) is being constantly emitted by the transceiver.
If the Locked tone is lost during the clamp tightening, you need to reacquire the
signal by modifying the elevation setting by +/- 2 degrees around the nominal
value.
If the Locked tone is not achieved, return to the nominal value and modify the
azimuth setting by +/- 2 degrees around the zero setting.
If neither of these measures helps to obtain the Locked tone, you need to repeat
the coarse pointing procedure.
To complete the dish pointing:
1. Using a spanner/ratchet, rotate the azimuth screw to change the azimuth settings
on the dish in any direction.

2. Once you can hear the audio signals reduce tone and staggering rate, reverse the
direction at once.
If, instead of stopping and reversing the direction, you continue too far, you may
lose the Locked state. In this case, you will hear a transition tone
(
Transition2Searching ).
3. At some point, you will hear the pitch increase, and the tone will change from
staggering to continuous (
Peak ). Continue in the same direction until staggering
tone starts again. Reverse the direction once again and stop as soon as you hear a
continuous tone.
