Peak
– At any given time during the pointing there is a maximum reception level
registered. This level will gradually increase as the pointing progresses. The peak
continuous tone is coupled to the maximum reception level.
Transition2Searching
- if the Locked state is lost during the pointing, there will be a
2-second transitional tone (as a police car siren), which will be followed be the
Searching tone.
Abort
– A mismatch between the parameters entered and the kit installed.

Coarse Pointing
To perform the coarse pointing:
1.
Verify that the nominal elevation, azimuth and skew values are set correctly.
Before you proceed to the next step:
Do not apply force to the reflector. Excessive pressure on the reflector can cause
reflector deformation.
Hold the dish assembly at the back structure and Az/El while rotating it.
2.
Rotate the dish as slowly as possible (approximately 1 degree per second) around
the pole in one direction until the beeping tone changes, indicating that the modem
is locked on the satellite. The Locked state is indicated by a 2-second transitional
tone (
Transition2Lock
).
