The cases that house the Norsat NewsLink Antenna/RF and Baseband/IF
units are weatherproof, and there should be no water penetration when all
winglocks are properly secured.

The cases will provide shock and vibration protection during storage, trans-
port and, in the case of the Baseband/IF unit, operation. However, care

The Antenna/RF unit is stored in two cases, the RF and Antenna Unit case,
Model 3200-RF, and the Accessories case, Model 3200-AC; refer to Figure 2
on page 8. The Baseband/IF unit is stored in one case; refer to Figure 3 on

page 8.
The Antenna/RF cases are equipped with a pressure relief valve that equal-
izes the pressure inside and outside the case. This relief is provided automat-
ically should the pressure difference become too large, thus preventing the
case from exploding due to extreme differences in atmospheric pressure.
Alternatively, the case may be under a vacuum and hard to open. The valve
can also be depressed by the user to manually equalize the pressure.
