2. OPERATION OF THE EQ 55
2.1 BASIC OPERATION OF THE EQ 55
The EQ 55 is an easy to use echo sounder whose functions are quickly accessible
through on-screen menus by means of a joystick.
Caution: Do not operate the EQ 55 with the transducers
out of the water. Operation at full transmit power with
the transducers out of the water risks permanent
damage to the transducers.
2.1.1 Turning the EQ 55 On.
The EQ 55 is turned on by pressing the rocker switch in the lower left hand corner
of the control panel.
2.1.2 Joystick
The EQ 55 is controlled through menus that you access by operating a joystick
located on the control panel. Below is a list of what happens when you move the
joystick. If you get lost in the menus, repeatedly push the joystick to the left, this
will move you up to each previous menu until you arrive at the MAIN MENU. To
make the MAIN MENU reappear push the joystick once to the right.
