C-Card; Start-Up; Cartography Notice; Feature Memory - Humminbird NS25 Operation Manual

C-Card

Check System Status "C-Card" field to confirm NS25 is reading C-Card information. If the fields
display "NONE," check card reader cable connection and make sure cards are securely seated.
When cards are properly inserted the C-Card field displays the card number, such as NA503.4.
Sonar
If the bottom is visible on-screen with digital depth readout, the unit is working properly.
Remember, the sonar signal cannot pass through air. If the unit is working properly, gradually
increase the boat speed to test high-speed performance. If the unit functions well at low-speeds
but begins to skip at higher speeds, the transducer installation requires adjustment.

Start-Up

The NS25 is completely automatic and easy to use. Simply press the POWER button and select
Start-Up. This mode determines your position and displays it on a map, tracks the bottom from 2
feet to 1000 feet displaying structure and suspended fish, and works at speeds from 0 to over 70
mph. Start-Up is the mode of operation for actual use of the NS25.

Cartography Notice

When starting up the NS25, a cartography notice displays to indicate which C-Map cartridges are
in the card reader.

Feature Memory

Any changes you make to the user settings while in Simulator or Start-Up (normal operation) are
retained in the unit's memory. This allows you to use the Simulator at home to experiment with
the various set-up options, and retain your selected settings for normal operation. However,
changes made while in Demonstration mode will not save.
