If a noticeable decrease in sensitivity (resulting in weak signal strengths)
and/or very few satellites being tracked is noted, try repositioning the
antennas to improve the satellite reception.
Mount the antenna at the desired location. Connect the supplied cable to the antenna.
Take appropriate lightning precautions as necessary. The GNSS antenna must be moun-
ted such that the antenna points to the sky, i.e. the connector side pointing down.
Note: Spectracom recommends applying an appropriate silicon grease
to the cable connection at the GNSS antenna in order to protect the
connection from moisture. An additional weatherproofing kit (P/N
221213) containing butyl rubber and plastic tape is also available from
Andrews Corporation, USA, phone +1.800.255.1479.
5.5 Maintenance and Service
We recommend to clean the front bezel filter regularly:
Remove the front bezel by unlocking it with the key, then pressing the red
release knob, then removing the bezel with both hands. While the bezel is
removed, check if the filter requires cleaning.
It is recommended that you keep a maintenance log of filter cleaning/replacement,
since its condition will affect the airflow throughout the whole system.
Note: When using a cabinet-style rack, close the cabinet doors after
completion of the maintenance work, to maintain proper cooling.
5.6 Product Registration
Spectracom recommends that you register your VelaSync so as to allow our Customer
Service and Technical Support to notify you of important software updates, or send you
service bulletins, if required.
