GMR 404/406 OPERATION

Radar Overview

The Garmin GMR 404/406 transmits a narrow beam of microwave energy in a rotating 360° pattern. When the transmitted energy contacts a target, some of that energy is reﬂ ected and returned to the scanner. The scanner collects the returned energy for processing and display. The GMR 404/406 is operated and adjusted using controls on the Gamin chartplotter. Radar data is presented on a dedicated Radar Page or as an overlay on the Map page. All radar controls are accessible on both pages.

The Radar Page

With the GMR 404/406 radar properly installed, at power up, the Garmin chartplotter should detect the GMR 404/406 as a new network connection.

Note: A software update may be needed for the GMR 404/406 to

function properly. If the message “Incompatible Software Version” is displayed when the chartplotter is powered on, the software in the chartplotter needs to be updated. A software update card is provided with the GMR 404/406.

When the new radar is detected, the chartplotter automatically adds a dedicated Radar Page to the pages list. If the Radar Page is not available, press and hold ADJ/MENU until the Main Menu is displayed. Use the Rocker to highlight the System tab, and select Radar from the Services list at the bottom of the page.

To Select the Radar Page for display:

1. Press PAGE to display the Pages list.

2. Using the Rocker, select Radar.

3. Press ENTER.

When the scanner is powered on, the Status Bar at the top of the Radar Page, shows the message “ Radar Warming Up” with a countdown to Standby Mode. The countdown is also displayed in the middle of the Radar Page. When the countdown reaches zero, the message changes to “Hold FCTN to transmit.”

As a safety feature, the scanner enters standby mode after it warms up. This provides the operator an opportunity to verify that the area around the scanner is clear before beginning radar transmission. It is important to remember that the microwave energy transmitted by the scanner can potentially be dangerous.

CAUTION: The GMR 404/406 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 scanner is clear. The GMR 404/406 transmits a beam approximately 12° above and below a line extending horizontally from the center of the scanner. Avoid looking directly at the scanner, the eyes are the most susceptible part of the body.

When the area surrounding the scanner is clear, press and hold FCTN. The message “Do you want to begin radar transmission?” is displayed. Select Yes, then press ENTER. Before transmission begins, the message “ Spinning Up” is shown while the radar antenna reaches nominal rotation speed. When the message disappears, the radar begins painting an image.

Range Rings

The Range Rings help to quickly determine the distance to a target. In the lower-right corner of the display are two scales. The upper scale is the current zoom scale. This scale is changed using the

RANGE keys. The zoom scale is represented by the Range Ring with tick marks around the circumference. The tick marks are arranged with major tick marks at thirty-degree increments and minor tick marks every ﬁ ve degrees. The tick marks can help in quickly determining the azimuth to a target. The lower scale represents the distance between the Range Rings.

Heading Line

The Heading Line is shown from your current position along the path of your current heading.

Digital Navigation Data

By default, the Radar Page shows one column of digital navigation data with four data ﬁ elds. The Radar Page can be conﬁ gured to show two columns of data with up to seven data ﬁ elds each. Each data ﬁ eld can be conﬁ gured to show a variety of data.
