Humminbird NS 10 - Manual (Page 65)

In hot weather, with direct sun on the display screen, it is normal for liquid crystal displays to
become dim. Use the display contrast adjustment to improve the contrast and also try to shield
the display from direct sun. A cool wet towel put over the control head will quickly lower the
temperature and improve contrast.
Check your battery to see that it is fully charged. The NS 10 will not operate on less than 11 volts.
Also, check the voltage level at the power connector. Bad connections from the battery terminals
to the power connector can result in a large voltage drop and loss of current. Try using the display
contrast adjust feature of the NS 10 to improve contrast.
6. The NS 10 turns off every time I start my engine.
This may be caused by the battery voltage being pulled down by the starter. Carefully check all
electrical connections from the battery terminals to the NS 10 power connector. Compare the
voltage at the battery to the voltage at the power connector to ensure that there is no voltage
drop. Correcting even a small voltage drop can make a difference. If an auxiliary battery is
available, using it will prevent a low voltage to the NS 10 while starting the boat.
