Bezel Fitment And Removal - Simrad NSS evo3 Installation Manual

Bezel Fitment and Removal

When fitting bezels, ensure hook tabs on back of each bezel recess in to opposing slots on
screen frame. Once flush with front surface of screen, slide top bezel to the left, and bottom
bezel to the right to lock in to place.
The bezel trim have been designed to be very low profile, and therefore fully conceal the
locking tabs that keep them from being accidentally disengaged from the mounting flange.
To release the locking tab, gently lever the centre of the bezel trim away from the mounting
flange. To remove the cover, simultaneously slide it sideways; to the right for the top bezel,
and to the left for the bottom bezel.
Transducer mounting location
Transducer location selection and installation are two of the most critical steps in sonar
installation. To function properly the transducer must be in the water at all times, and in a
location that has a smooth flow of water when the boat is moving.
Research
Before starting the installation of the transducer, check the following:
• Find out if the boat builder has a recommended installation location
• Establish the direction of rotation of the propeller(s)
• With the boat traveling at cruising speed, watch the water flow behind the boat to find
the area with the smoothest flow (least bubbles)
Select a transducer location
The primary aim is to stay clear of propeller and hull generated turbulence, while mounting
the transducer as close to the center of the vessel as possible.
