Navman 4433 Scroll speed, Fish symbols, Digit size, Palette, Interference filter, Pulse power

Scroll speed Fish sensitivity

Use this to set the scroll speed on the display. There is a choice of: Very Fast, Fast, Medium, Slow and Pause. The depth of the water also affects the speed of the display.

Faster scroll speeds combined with a slow boat speed (typically between 2 and 6 knots) shows the most fish detail. Medium or Slow scroll speeds result in sonar information being displayed over a longer period, but with less detail. See Section 4-1 Interpreting the display, for more information.

Fish symbols

These appear only in the main sonar displays. Fish symbols can be shown in three ways:

•As a fish symbol (Symbol).

•As a fish symbol with the depth

(Symbol+depth). The depth is shown beside the fish symbol.

•As a depth (Depth). The depth is shown above where the fish was detected

•Switched off (Off) so that echoes are not converted to fish symbols but are displayed directly.

See section 4-3 Fish detection and display, for more information about fish symbols.

3-3 Setup > Fuel (available on 4433 only)

Use this function to adjust the minimum fish detection level. Select Low to reject noise and small fish. Select High to detect maximum number of fish.

Digit size

Use this to remove or change the size of the depth display on the sonar displays. There is a choice of: Small, Medium and Large.

Palette

Use this to select a color palette. Each color within the palette represents a different echo strength, as shown on the sonar displays.

There is a choice of three color palettes: Black, White and High Contrast.

Interference filter

This filters the echo signal to reduce high-level, spiky interference, such as engine noise and makes small fish harder to see.

Selectto add filter.

Pulse power

This can be used to specify the power output of the transmitted ultrasonic pulse. Low power output conserves the boat’s battery, but only works in shallow water.

There is a choice of Auto, Low, Medium or High. The Auto setting is recommended.

These features can be used only when the optional single or twin engine fuel kit has been installed.

Press MENU once or more until the Setup menu is displayed, then select Fuel:

It is recommended that the fuel tank capacity is measured by draining the fuel tank, then filling it to capacity. After filling, note the reading from the fuel dispenser’s gauge.

Note: Beware of air pockets, especially in underfloor tanks.

Warning

Navman fuel kits are only suitable for petrol/ gasoline engines. Fuel consumption can change drastically depending upon the boat loading and the sea conditions. Always carry adequate fuel for the journey, plus a reserve.

Tank full

Select Tank full each time the fuel tank(s) are completely refilled. When asked Are you sure? select Yes. Otherwise, the reading on the Fuel display (see section 5-6 Fuel Display) and the Low Fuel Alarm (see section

3-5 Setup > Alarms) are meaningless.

Set remaining

Before doing a partial refill of the tank or removing fuel manually from the tank (for example, by siphoning it off):

1.Note the Remaining reading on the Fuel display.

2.Note how much fuel is added or removed.

3.Calculate how much fuel is now in the tank.

4.Select Set remaining and update the reading.
