Normal Operation; Simulator - Humminbird 788c Operation Manual

Normal
Use Normal for on-the-water operation with a transducer connected. In
addition, your Fishing System uses advanced transducer detection methods to
determine if a transducer is connected.
If a functioning transducer is connected, Normal operation will be selected
automatically at power up, and your Fishing System can be used on the water.
Exit Normal operation by powering your Fishing System off.

Simulator

Use Simulator to learn how to use your Fishing System before taking your boat on
the water. The Simulator is a very powerful tool that provides a randomly-updated
display which simulates on the water operation.
Selecting Simulator from the Start-Up Options Menu allows you to pre-configure
your Fishing System for on the water operation. Any menu changes you make will
be saved for later use. We recommend going through this manual while using the
Simulator, since all of the menus function and affect the display in the same way
as they would in Normal operation.
NOTE: To get the full benefit of the Simulator, it is important to select Simulator
manually from the Start-Up Options Menu as opposed to letting the Fishing System
enter Simulator automatically (as it will if a transducer is not connected and you do
nothing during power up).
A message will appear on the display periodically to remind you that you are
using the Simulator.
Exit the Simulator by powering your Fishing System off.
