Simrad NSS evo3S Installation Manual

Compass safe distance
The unit outputs electromagnetic interference that can cause inaccurate readings on a
nearby compass. To prevent compass inaccuracy the unit must be mounted far enough
away so the interference does not affect compass readings. For minimum compass safe
distance, refer to "Technical specifications" on page 43.
GPS
It is important to test the GPS performance before the location of the unit is decided.
Construction material (steel, aluminum, or carbon) and heavy structure might affect GPS
performance. Avoid a mounting location where metal obstacles block the view of the sky.
A well placed external GPS module can be added to overcome poor performance.

Note: Consider the lateral swinging if mounting the GPS sensor high above the sea level.
Roll and pitch might give false positions and affect the true directional movement.
Touchscreen
Touchscreen performance can be affected by the location of the unit. Avoid locations where
the screen is exposed to:
• Direct sunlight.
• Prolonged rainfall or floating water.
