The Par. 7.4 has been deleted. The Par. 7.2 , Par. 7.3 and Par. 7.11 are to be substitued
with the following ones.
7.2 WHAT ARE PRESET MODES?
Preset modes are pre-defined settings of the Fish Finder operating parameters. You can use
them to quickly set the Fish Finder in the most commonly used operating modes. These are:
·CRUISE : sets the Fish Finder in full auto mode with the sensitivity settings
(GAIN OFFSET, NOISE level and STC) optimized for displaying
the bottom while underway.
·FISH : sets the Fish Finder in full auto mode with the sensitivity setting
optimized for fish finding.
7.3 HOW CAN I RESTORE THE FISH FINDER DEFAULT OPERAT-
ING PARAMETERS?
While the Fish Finder page is shown, press [MENU] and move the ShuttlePoint knob to
Transducer Setup and press [ENTER]. Move the ShuttlePoint knob to Set Defaults and
press [ENTER]. Press [CONFIRM] on the C175C and CP1000C, or on the CP155C press
[ENTER]. Note that this operation set all default settings, not only the working defaults.
7.11 AT A VERY SHALLOW RANGE UPPER HALF OF THE SCREEN
APPEARS ALMOST COMPLETELY FILLED BY THE SUR-
FACE CLUTTER. HOW CAN I ELIMINATE IT?
This is normal in shallow waters. To clean up the surface clutter without degrading the digital
depth readout algorithm functionality there are two modes: 1) If Surface Declutter = OFF it
is possible to set the STC value to custom setting the STC lenght to the same size of the
surface clutter, and increasing the STC strenght until the image on the screen cleans up.
Please note that in very shallow waters it is usually better to switch to manual gain mode
to reduce gain fluctuation due to rapidly changing bottom conditions. 2) Using Surface
Declutter, increase the Surface Declutter value until the surface declutter disappears
completely.
