The program starts up using the same settings as the last time you used it. If these
settings are acceptable, continue operation. If you wish to alter any of the settings,
see the relevant procedures.
6 To lower the transducer, press
Down
on the Operating Panel.
While the transducer is moving the indicator lamp flashes, and an
audible signal is sounded. When the requested position has been
reached, the indicator lamp is lit, and the audible signal stops.
Alternatively, use the
Hull Unit
function on the top bar to lower
the transducer.
7 At the bottom of the
Main
menu, observe that the
Operation
icon is flashing.
The icon is flashing to indicate that even if the SN90 is turned on, "pinging" is
disabled. The SN90 is in
Normal mode, but
TX Power
is set to Off to prevent
transmissions. This is for safety reasons.
8 Set
Tx Power
to Maximum (or any other power rating) to start pinging.

Lowering and hoisting the transducer from the user interface
The Operating Panel controls the lowering and hoisting of the transducer. Dedicated
buttons are provided for the physical transducer locations. You can also control the
transducer movements from the top bar on the SN90.
Context
The
Hull Unit
dialog box allows you to lower and
hoist the transducer. The dialog box also provides
status information about the transducer position. You
can monitor the current position of the transducer, and
make changes to the position defaults.
Caution
If the transducer hits larger objects or bottom, the
transducer shaft may be bent, or - in worst case - it can
be broken off. A broken transducer shaft will cause water leakage through the top of
the shaft. If you suspect that the transducer shaft is seriously damaged with holes, do
not retract the transducer to its upper position.
To prevent serious damage to the vessel or the vessel stability, you must have a water
pump and a warning system in the sonar room.
