NorthStar 972 User Manual

Northstar 972

The 972 can be connected to a wide 
variety of compatible marine devices, 
including Northstar’s echo sounder and 
radar. A qualified marine electronics tech-

nician should perform these installations. 
For details, contact your local authorized 
Northstar dealer. 

To help retain the 972’s best possible 
performance, Northstar recommends the 
following: 

keep fingerprints off the display screen 
(remove any prints with a lens cleaning 
cloth) 

remove dirt and grime using a soft 
cloth and Windex or soap and water

don’t scratch the display by wiping a 
sandy or salty cloth across it

use the 972’s protective plastic 
sunshield when not in use (excessive 
heat from the sun can cause damage) 

don’t open the 972 case—there aren’t 
any user-serviceable parts inside

always keep the rear connectors’ plastic 
caps on when they are not in use (the 
connectors are not waterproof unless 
covered)

Be careful when cleaning the glass window 
covering the display screen. Although the 
window is scratch-resistant, you may 
damage the anti-reflective coating if you 
use a dry cloth to wipe dirt off. Always use 
a damp cloth with plenty of water to 
remove salt or dirt. To remove any oil or 
grease on the screen, use a clean, dry 
microfiber-type lens cleaning cloth or a 
small amount of window cleaner.    

Avoid touching the window with your 
fingers. The natural oils from your hand 
will temporarily affect the characteristics of 
the screen and cause your fingerprints to 
appear as bright reflections. Fingerprints 
will disappear when you clean the screen 
as described in the previous paragraph.
