5.2.4 Transducer Setting
The Transducer Setting function enables the user
to optimise the operation of the DS35 for the
particular transducer installed. Transducer
performance varies widely, larger diameter
transducers produce strong signals resulting in
improved deep water performance but can suffer
from reduced shallow water performance, due to
transducer ringing. Smaller transducers produce the
opposite effect, with improved shallow water
performance and reduced deep water performance.
There are three values of transducer settings (1 to
3). The lower numbers improve the shallow water
performance and may produce reliable readings to
below 3 feet. It is recommended to use the lowest
number possible if shallow water performance is
important. It must also be noted that in situations
where the DS35 is tracking the bottom and displaying
a consistent depth but occasionally displaying “--”
or erroneous depths of 3 to 4 feet, that this generally
indicates the transducer setting is too low and should
be increased. The transducer settings only affect
the instrument operation in the 2.5 to 4 feet region.
The transducer settings have no affect in water
deeper than 4 feet.
The transducer setting is a secondary function and
can be accessed as shown in the diagram below.

5.3 Simulation
Simulation is a feature used to demonstrate
the operation of the instrument. The owner
may activate the simulation mode by
holding the
key down and turning
on the power to the instrument. Simulation
is in operation when the right-hand digital
of the display counts up or down one digit
at a time. To disable simulation mode, turn
off the power and hold the
key down
as power is turned on.
