Select Settings > My Vessel > Keel Offset.

Select   or   based on the location of the transducer.

Enter the distance measured in step 1.

From a sonar view, select Menu > Record Sonar.

Before you can stop recording the sonar, you must begin

recording it (page 16).

From a sonar view, select Menu > Stop Recording.

If you are using a depth-capable transducer, or are receiving

water depth information over NMEA 0183 or NMEA 2000,

you can view a graphic log of depth readings over time. If you

are using a temperature-capable transducer, or are receiving

water temperature information over NMEA 0183 or NMEA

2000, you can view a graph of temperature readings over

time.
The graphs scroll to the left as information is received.
Select Sonar > Data Graphs.

You can indicate the amount of time and the range of depth

that appear in the depth and water temperature graphs.

Select Sonar > Data Graphs > Menu.

Select Depth Graph Settings or Temperature Graph

Settings.

Complete an action:
• To set a time-elapsed scale, select Duration. The

default setting is 10 minutes. Increasing the time-

elapsed scale allows you to view variations over a

longer period of time. Decreasing the time-elapsed

scale allows you to view more detail over a shorter

period of time.

• To set the depth-range or temperature-range scale,

select Scale. Increasing the depth-range scale allows

you to view more variation in readings. Decreasing

the scale allows you to view more detail in the

variation.

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. Avoid looking directly at the radar, because the

eyes are the most susceptible parts of the body.

When you connect your chartplotter to an optional Garmin

marine radar, such as a GMR 1206 xHD 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.

NOTE: Not all modes are available with all radar devices and

all chartplotters.
Select Radar, and select a mode.
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 Sentry 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: Shows a full-screen image of the

gathered radar information on top of the Navigation chart.

The Radar overlay displays data based on the most-

recently used radar mode.

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.

With the chartplotter off, connect your radar as described

in the radar installation instructions.

Turn on the chartplotter.
The radar warms up and a countdown alerts you when

the radar is ready.

Select Radar.

Select a radar mode.
A countdown message appears while the radar is starting

up.

Select Menu > Transmit Radar.
