Garmin GPSMAP 8000 Manuale Utente

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.

NOTE: Not all models support sonar recording.

Insert a memory card into the card slot.

From 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.

Before you can stop recording the sonar, you must begin 

recording it (

From a sonar view, select Menu > Stop Recording.

Insert a memory card into the card slot.

Select Sonar > Sonar Recordings.

Select a recording.

Select Delete.

Before you can play back the sonar recordings, you must 

download and install the HomePort™ application and record 

sonar data onto a memory card.

Remove the memory card from the device.

Insert the memory card into a card reader attached to a 

computer.

Open the HomePort application.

Select a sonar recording from your device list.

Right-click the sonar recording in the lower pane.

Select Playback.

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.

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.

From a Radar screen, select Menu > Radar Menu > 

Change Radar.

Select a 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 > Menu > Radar Menu > Change Radar.

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

Select Menu > Transmit Radar.

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.

• 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.
