POS Computer System -
POS MV V4-1 paragraphs, starting on page

the environmental limits starting on page 7-3 when installing the PCS.
Installation
Important:
1. Equipment shall be installed by qualified personnel.
2. The PCS (POS MV V4) shall be grounded through the ground prong of
the power plug; if not, then the safety ground screw shall be used.
3. The PCS (POS MV V4-1) shall be grounded via the safety ground screw.
4. Power to the POS system should be protected by a user-supplied,
resettable circuit breaker.
GNSS System
Do not connect any input to the PPS OUT port. Connecting a
signal input to this port will damage the PCS interface circuitry.
The PCS includes a primary and a secondary GNSS receiver for operation
with the POS MV.
Multipath reflections of the received GNSS signals are the dominant source of
measurement errors in the heading aiding information computed by the GNSS
Azimuth Measurement Subsystem (GAMS). Reflectors can include flat
surfaces on the vessel and the surface of the sea.
