The Sygnus SHC can be aligned using the Built in RSSI buzzer
Sygnus SHC units have a built in RSSI buzzer that indicates the best mounting location.
The buzzer is beeping at four tone levels:
• Fast – highest signal obtained so far.
• Medium – the current alignment is lower than the highest signal obtained so far.
• Slow – the current alignment is much lower than the highest signal obtained so far.
• No sound – no reception of the base station at all (or the buzzer is off).
In order to select the best alignment of the unit, please perform the following steps. Select the best
location:
1. When the unit is first connected to power, the buzzer will be automatically activated in one of the
following modes:
• No sound – there is no reception.
• Fast beep – there is a reception (which is currently the maximum signal obtained).
2. Take the unit to the selected location and align the antenna in the link’s direction. Listen to the
buzzer tone level. Any sound (fast, medium or slow) indicates a reception.
3. Change the antenna alignment to the left, right, up and down in order to scan for the maximum
reception point.
4. After scan is complete, align the antenna to the location where the buzzer beeps at the fast rate,
indication the maximum reception.
5. Mount and secure the unit by fastening the mounting screws.
The buzzer is automatically shut down within 20 minutes. You can reactivate it or shut it down
manually using the Link Manager advanced window.
