Installation Guide
1001001-3
RECOMMENDED PHYSICAL INSTALLATION
Transponder unit should be mounted in a protected area and compass
safe distances kept in mind (see table on the right). VHF antenna must be
mounted vertically, free of reflective objects, minimum distance to other
VHF antennas 1.5m and out of the radar beam. GPS antenna must have
an omnidirectional view of the sky for ideal reception.
SYSTEM MODE
Important:
The Nauticast A2 can operate in two different system modes,
Class A mode
(default) and
Inland mode
.
Inland mode is applicable to European river going vessels. Set mode in:

This installation guide serves as a complement to the
product manual (Art.No. 1001001-2), included on the
Nauticast Data Card (USB-Stick).
Installation of the
Nauticast A2 AIS System should always be planned
and executed by authorized personnel.
