FISH 4100 Installation and Operation Manual NAVMAN

Alarms can be enabled to automatically detect certain

conditions, such as the water being too shallow. The

trigger settings for the alarms can be defined to suit

the boat and individual preferences.

The FISH 4100 has four alarms, TOO SHALLOW,

TOO DEEP, FISH ALARM and LOW BATTERY.

The FISH 4150 has two extra alarms, TEMP VALUE

and TEMP RATE.

The alarm symbols and beeper cycles for all of the

alarms are shown in section 4-1. The FISH ALARM

is three short beeps, the TOO SHALLOW ALARM is

a rapid continuous beep while all others are a slower

continuous beep.

When an alarm condition is met, then:

· the beeper sounds.

· the ALARMS menu is displayed on the

screen with the activated alarm(s) flashing.

Press any key to acknowledge the alarm, stop the

Select MAIN MENU - HISTORY to display the

HISTORY screen.

The HISTORY screen displays the most recent

echoes on the right of the screen and the oldest

echoes on the left. These eventually disappear off

the screen.

The vertical bar on the right edge of the screen is the

zoom bar. This shows the zoom range. To adjust the

zoom range see section 3-4.

beeping and remove the ALARMS menu. This does

not disable the alarm. The symbol will continue to

flash until the alarm condition is no longer present.

Alarms automatically re-enable

The TOO SHALLOW, TOO DEEP and LOW

BATTERY alarms automatically re-enable when the

value moves outside the alarm trigger setting.

The TEMP VALUE alarm automatically re-enables

when the temperature is more than 0.45°F (0.25°C)

above or below the alarm trigger setting.

The TEMP RATE alarm automatically re-enables

when the rate of temperature change falls below the

trigger setting by more than 0.2°F (0.1°C) per minute.

Enabling Alarms and Changing Trigger

Values

See section 4-1 for information about enabling alarms

and changing the trigger values.

3-2 HISTORY screen operation

the boat. This means that the HISTORY screen

display moves across the screen more quickly than

when the boat is travelling in deep water. In deep

water, the echoes take longer to travel between the

objects and the boat, producing a display that moves

across the screen more slowly.

Note 1: Different fish symbols can be selected (see

section 4-4).

Note 2: The depth of bottom can be adjusted for keel

offset (see section 4-7).

Range

Range is the depth of water displayed vertically. The

NAVMAN fishfinder has two range modes, Auto

Range and Manual Range:

· In Auto Range, the fishfinder adjusts the depth

range automatically so that the bottom is always

shown in the lower part of the screen. The use

of Auto Range is recommended.

· In Manual Range, the fishfinder shows only a

selected depth range. In areas of rapidly

changing bottom depth, such as the sea floor

around pinnacles, it can be useful to prevent

the screen from rescaling to always show the

bottom. If the bottom is deeper than the

specified depth range, it will not be shown on

the display screen.

To change the range mode, (see section 3-8).

The HISTORY screen does not show a fixed distance

travelled by the boat; rather, it displays what has

passed below the boat during a certain period of time.

The actual display depends upon the boat speed and

the depth of the water.

As the boat travels through shallow water, the echoes

have less distance to travel between the objects and
