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.

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.

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. 

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.

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.

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

Select       to add filter.

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.

(available on 4433 only) 

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. 

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.

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.

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.
