Sonar Recordings Recording the Sonar Display NOTE: Not all models support sonar recording. 1 Insert a memory card into the card slot. 2 From a sonar view, select Menu > Sonar Setup > Sonar Recording > Record Sonar. 15 minutes of sonar recording uses approximately 200 MB of space of the inserted memory card. You can record sonar until the card reaches capacity. Stopping the Sonar Recording Before you can stop recording sonar, you must begin recording it (Recording the Sonar Display, page 23). From a sonar view, select Menu > Sonar Setup > Sonar Recording > Stop Recording. Deleting a Sonar Recording 1 Insert a memory card into the card slot. 2 From a sonar view, select Menu > Sonar Setup > Sonar Recordings > View Recordings. 3 Select a recording. 4 Select Delete.

Radar

WARNING

The marine radar transmits microwave energy that has the

potential to be harmful to humans and animals. Before

beginning radar transmission, verify that the area around the

radar is clear. The radar transmits a beam approximately 12°

above and below a line extending horizontally from the center of

the radar.

When the radar is transmitting, do not look directly at the

antenna at close range; eyes are the most sensitive part of the

body to electromagnetic energy.

NOTE:

Not all models support radar.

When you connect your compatible chartplotter to an optional

Garmin marine radar, such as a GMR

™

1226 xHD2 or a GMR 24

HD, you can view more information about your surroundings.

The GMR transmits a narrow beam of microwave energy as it

rotates to a 360° pattern. When the transmitted energy contacts

a target, some of that energy is reflected back to the radar.

Radar Display Modes

NOTE:

Not all modes are available with all radar devices and all

chartplotters.

Select Radar.

Cruising Mode

: Shows a full-screen image of the gathered

radar information.

Harbor Mode

: Intended for use in inland waters, this mode

works best with short-range signals (2 nm or less).

Offshore Mode

: Intended for use in open waters, this mode

works best with long-range signals.

Sentry Mode

: Allows you to put the radar into timed-transmit

mode, in which you can configure a radar transmit and

standby cycle to conserve power. You can also enable a

guard zone in this mode, which identifies a safe zone around

your boat. If you switch from Sentry mode to another mode,

the radar switches to full-time transmission and disables all

guard zones.

Radar Overlay Mode

gathered radar information on top of the Navigation chart.

The Radar overlay displays data based on the most recently

used radar mode.

Transmitting Radar Signals

NOTE:

As a safety feature, the radar enters standby mode after

it warms up. This gives you an opportunity to verify the area

around the radar is clear before beginning radar transmission.

the radar installation instructions.

Turn on the chartplotter.

Adjusting the Radar Range

The range of the radar signal indicates the length of the pulsed

signal transmitted and received by the radar. As the range

increases, the radar transmits longer pulses in order to reach

distant targets. Closer targets, especially rain and waves, also

reflect the longer pulses, which can add noise to the Radar

screen. Viewing information about longer-range targets can also

decrease the amount of space available on the Radar screen for

viewing information about shorter-range targets.

•

Select

•

Select

to increase the range.

Tips for Selecting a Radar Range

•

Determine what information you need to see on the Radar

screen.

For example, do you need information about nearby weather

conditions or targets and traffic, or are you more concerned

about distant weather conditions?

•

Assess the environmental conditions where the radar is being

used.

Especially in inclement weather, longer-range radar signals

can increase the clutter on the Radar screen and make it

more difficult to view information about shorter-range targets.

In rain, shorter-range radar signals can enable you to view

information about nearby objects more effectively, if the rain

clutter setting is configured optimally.

•

Select the shortest effective range, given your reason for

using radar and the present environmental conditions.
