The Signal Validation ???
The Antenna Offset allows you to virtually offset your antenna.
That is, if you are forced to place the antenna in a location other
than where you want your position fix calculated (due to super-
structure or other high power antennas), you can place the antenna
in a practical location. Then enter the appropriate Antenna Offset,
and the receiver will calculate your position in the place where you
would have preferred to place the antenna. For example, if the
antenna is placed on the port wing of a container ship, and you want
to calculate the ship's position based on the keel line and half the
length of the ship, you might enter an offset of 10 meters Starboard
and 53 meters Forward.
It is important to note that many applications where an antenna
offset is desirable, will also require very precise positioning at slow
speeds to locate crab pots, place buoys, etc. In applications where
the boat speed is very slow, the course over ground (COG) position
will begin jumping more and more as you approach a full stop. This
will cause position jumps and these jumps will be more severe the
farther the antenna offset projection is. Should you choose to use
this feature, it is required that you use a compass input to the
receiver, so that the proper orientation between the antenna, the
antenna offset, and the boat's heading can be maintained.

Init Pos - Initial Position Entry

This screen is provided to help the receiver provide a faster first
position fix after a cold start (no almanac). While the receiver is
capable of computing position fixes without any user input, this
feature can cause a position fix to occur several minutes earlier in a
cold start condition. The only other time this feature is useful, is
