9.4 Place of installation of display unit
The display unit can be installed on desktop, wall surface, or ceiling. Determine
the place to install the display unit that is convenient for navigation and general
operation after considering the following suggestions:
- a place where you can see the ship’s bow when you raise your eyes from the
display.
- a place where there is limited exposure to direct sunlight – see environment
temperature limits in 9.11 Specifications.
- a place where there is good ventilation and minimum vibration.
- a place where the minimum distance to a magnetic compass is 500mm (20”).
9.5 Installation of Dual Station DS40/42/50/52
The DS models are remote control units for the EQXX Echosounder.
The units with the same model numbers are identical in size e.g. DS42 and
EQ42, so the same installation guides can be used when performing the
installation. When choosing a dual station, the unit does not have to match the
main unit in size, as all the mentioned units are compatible.

is available on the dual station’s NMEA2 receptacle.
