Reducing the transmit rate increases the spacing between transmit pulses and can resolve self-interference.

Transmit Power: Reduces transducer ringing near the surface. A lower transmit power value reduces transducer ringing.

Filter Width: Defines the edges of the target. A shorter filter defines the edges of the targets, but may allow more noise. A longer filter creates softer target edges, and may also reduce noise.

Transducer Diagnostics: Shows details about the transducer.

Flip Left/Right: Changes the SideVü view orientation from left to right.

Sonar Recordings

Recording the Sonar Display

NOTE: Not all models support sonar recording.

1Insert a memory card into the card slot.

2From a sonar view, select Menu > 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 the sonar, you must begin recording it (Recording the Sonar Display).

From a sonar view, select Menu > Stop Recording.

Deleting a Sonar Recording

1Insert a memory card into the card slot.

2 Select Sonar > Sonar Recordings.

3 Select a recording.

4 Select Delete.

Playing Sonar Recordings

Before you can play back the sonar recordings, you must download and install the HomePort™ application and record sonar data onto a memory card.

1Remove the memory card from the device.

2Insert the memory card into a card reader attached to a computer.

3Open the HomePort application.

4Select a sonar recording from your device list.

5Right-click the sonar recording in the lower pane.

6 Select Playback.

Radar Display Modes

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

Select Radar > Menu > Radar Menu > Change 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 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: 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.

Dual Range Mode: Provides a side-by-side view of both short- range and long-range radar data.

Changing the Radar Mode

1From a Radar screen, select Menu > Radar Menu > Change Radar.

2Select a 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.

1With the chartplotter off, connect your radar as described in the radar installation instructions.

2Turn on the chartplotter.

The radar warms up and a countdown alerts you when the radar is ready.

3Select Radar > Menu > Radar Menu > Change Radar.

4 Select a radar mode.

A countdown message appears while the radar is starting up.

5 Select Menu > Transmit Radar.

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. Avoid looking directly at the radar, because the eyes are the most susceptible parts of the body.

NOTE: Not all models support radar.

When you connect your compatible 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.

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 to decrease the range.

•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.
