NOISE REJECTION
The UItraNavGPS's
noise
rejection
fea-
ture is an effective tool
in
combating
noise.
In sonar
terms,
noise is
any
undesired
signal.
It is caused
by
elec-
trical
and mechanical sources such as
bilge pumps, engine
ignition systems
and
wiring,
airbubbles
passing
overthe
face of the
transducer,
even vibration
from the
engine.
In
allcases,
noise can
produce
unwanted marks on the dis-
play.
The UltraNavGPS has atwo
step
noise
rejection system.
When the unit
is turned
on,
the noise
rejection
is on normal.
If
you
have noise
problems
(identified by
random lines or dots
on the
display), try changing
the noise
rejection
level to
high.
