Northstar Explorer D210 Installation and Operation Manual

8

The instrument can be easily installed in different 
types of instrument panels.

1.   Select a suitable location for the instrument. 

When selecting the location for mounting, 
the following are recommended:

• 

Controls of the instrument must be 
accessible to the user.

• 

Electrical connections must be routed to 
the boat system as directly as possible, 
minimising the length of cable where 
practical.

• 

Location should provide as much 
protection from the elements as possible.

• 

The panel for mounting the instrument 
should be 3 mm to 19 mm (1/8 to 3/4 
inch) thick.

• 

The space behind the instrument panel 
must have a depth of at least 95 mm (3.75 
inches).

2.  Drill a 51 mm (2-inch hole) on the instrument 

panel in the selected location.

3.  With the mounting bracket removed, insert 

the instrument into the hole until the back 
of the face plate is flush with the outside 
mounting wall.

4.  Slide the bracket over the body of the 

instrument. Note: Orient the bracket in such a 
manner that it does not cover the buzzer.

5.  Tighten the mounting nut until the bracket is 

secure.

6.  Connect the power cord at the back of the 

instrument to a 12 V power supply which is 
active whenever the ignition switch is on. 

The red lead should be connected to the 
positive terminal of the power supply via a 1 
amp fuse or a 1 amp circuit breaker. The black 
lead should be connected to the negative 
terminal.

Your depth sounder is designed for years of trouble free operation assuming proper installation and care 
are provided. Following the operation and installation guidelines in this manual should ensure optimum 
performance of the instrument. In the unlikely event that the instrument shall fail to perform or shall 
need servicing, contact the dealer whom you purchased your Explorer D210 from.

7.  Obtain the power from a 12 V source as 

directly as possible. Avoid power circuits 
which share loads with ignition, alternators, 
radio transmitters, etc. Excessive electrical 
noise associated with such devices may 
prevent the instrument from operating 
properly.

8.  Connect the RCA phono plug on the 

transducer cable to the instrument. Extension 
cables are available from your Northstar 
dealer if the transducer cable is too short.
