Transducer Settings - Raymarine A Series A50 User's Reference Manual

Transducer settings

Nearby vessels equipped with a fishfinder, or certain physical condi-
tions (like hard seabeds), can affect the DSM. Its setup menus
enable you to change settings to allow for this.
Note: The setup options available depend upon the transducer
fitted to your vessel.
Fishfinder settings should not ordinarily require adjustment.
To open the fishfinder transducer settings menu:
1. Make a fishfinder window active.
2. Press and hold the PAGE/MENU button.
3. Use the trackpad to select the Transducer Settings option.
Transducer options
• Select Transducer
When selecting a transducer, the A-Series displays a list of pos-
sibilities from which you can choose.

This option is only available if the selected transducer is one
that does not include an integrated speed transducer.

the transducer frequencies.

Normally enabled, you can disable the ping when appropriate: to
test other equipment, or if there is a diver beneath the vessel, for
example.
