When the
UItraNavGPS is turned on for
the
first time,
the
digital depth display is
located
atthetop left cornerof the screen.

display
comes from
a
separate digi-
tal sonar built into the unit. It displays
only the bottom depth. If it loses the
bottom, the last known
depth will flash on
the
display. When the digital finds the
bottom, it will automatically display the
bottom depth again. ____________
The

features
off

FISH I.D. ON 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.
