Function Keys (F1, F2)
Function keys F1 and F2 work like the auto dialing feature on a
telephone, instantly calling out desired settings to perform spe-
cially assigned functions. These keys provide optimum sonar
settings for a specific purpose with a single key operation.
Each function key can be assigned a combination of particular
sonar settings which will be most suited to a specific objective,
for example, detection of a fish school. Five programs are avail-
able: two user programs (User 1, 2) and three task-specific pro-
grams (Setup 1, 2, 3). The default settings of these programs are
shown in the table below. Note that the “Setup” programs can-
not be changed.
