American Systems Only)
As noted in Section 2.3.6.1, "Connecting the Antenna RF Signal

However, please refer to Section 3.1.8, "Multiswitch Interference,"
for an explanation of a potential issue with the use of any type of
multiswitch.

manual for service and warranty information. If the IRD is both
configured properly and fully functional, contact your local KVH
dealer or service center for assistance.
