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.

1

With the chartplotter off, connect your radar as described in 

the radar installation instructions.

2

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

radar is ready.

3

Select

.

4

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

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.
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.

Zooming In and Out of the Radar Screen

• Pinch two fingers together to zoom out.
• Spread two fingers apart to zoom in.
• Drag the screen to pan, and then select   or   to zoom, if 

necessary.

Marking a Waypoint on the Radar Screen

Sentry Mode

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 and 

sounds an alarm when a radar object enters the zone. Sentry 

mode works with all Garmin GMR model radars.

Setting the Standby and Transmit Times

Before you can set the standby and transmit times, you must 

enable timed transmit (

To help conserve power, you can indicate the radar standby 

time and the transmit time to implement periodic radar signal 

transmissions at set intervals.

Radar Targeting and MARPA

Radar targeting enables you to identify and track objects.
Mini-automatic radar plotting aid (MARPA) is primarily used for 

collision avoidance. To use MARPA, you assign a MARPA tag 

to a target. The radar system automatically tracks the tagged 

object and provides you with information about the object, 

including the range, bearing, speed, GPS heading, nearest 

approach, and time to nearest approach. MARPA indicates the 

status of each tagged object (acquiring, lost, tracking, or
