FUNCTION KEYS
Similar to the quick dialing function on a telephone, the five
function keys (F1–F3) on the main panel record control and menu
settings and replay them back exactly as programmed. The items
you can program are gain, display mode, TX ON/OFF, USER
menu, SYSTEM menu, DATA SET menus and data setting win-
dow. The function keys are useful for quickly setting up the so-
nar for a specific purpose such as seabed detection.
