BASIC OPERATION

This section covers the features and operation of the GMR 404/406.

Understanding Radar

The 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 reflected and returned to the scanner. The scanner collects the returned energy to process and display. Your GMR 404/406 is operated and adjusted using controls on your Garmin Marine Network chartplotter. You can view radar data on the Radar Page or as an overlay on the Map Page. All radar controls are accessible from both pages.

When you turn on the radar, the status bar shows the message "Radar Warming Up" with a countdown to Standby Mode. The countdown also appears in the middle of the Radar Page. When the countdown reaches 0 (zero), the "Hold FCTN to transmit" message appears.

As a safety feature, the radar enters standby mode after it warms up. This gives 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 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 scanner. Avoid looking directly at the scanner, because 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 shown. Select Yes, and then press ENTER.

BASIC OPERATION > UNDERSTANDING RADAR

Before transmission begins, the message “Spinning Up” is shown while the radar antenna reaches nominal rotation speed. After the message disappears, the radar begins painting an image.

Understanding the Radar Display

The Radar Page shows a status bar along the top, user-configurable digital navigation data down the right side, a Heading Line, and Range Rings. Soft keys that allow quick access to radar functions and setting changes appear along the bottom of the page.

2 GMR 404/406 Owner's Manual

Using Range Rings

Use the Range Rings to quickly determine the distance to a target. The lower-right corner of the screen contains two scales. The top scale value represents the distance from the center of the radar display to the outermost complete ring. The bottom scale represents the ring separation or the distance between the Range Rings. Use the RANGE keys to zoom in or out. The tick marks on the Range Rings are arranged with major tick marks at 30 degree increments and minor tick marks every five degrees. The tick marks can help in quickly determining the azimuth to a target.

Heading Line

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

Radar Page

A properly installed radar is detected as a new network connection when you turn on your Garmin Marine Network chartplotter.

NOTE: A software update may be needed for the radar to function properly. If the message "Incompatible Software Version" appears when you turn on your chartplotter, you must update your chartplotter software. A software update card is provided with the GMR 404/406.

MARPA Sub Tab

The MARPA sub tab contains settings for Vector Length, Target History, Own Vessel Safe Zone, Time To Safe Zone, Safe Ring Zone, and Velocity Reference.

The available MARPA sub tab options are:

• Vector Length— predicts the target's approximate position at a set time interval. This setting determines the length of the Vector Line, based on the time interval setting and the target's speed. The time interval settings range from .05 minutes to 60 minutes.
• Target History— is a trail showing a target's movement. Target History can be turned On or Off.
• Own Vessel Safe Zone—is a circular area defined by a range setting that is centered on your own vessel. If a target enters the defined area an alarm is sounded. The Safe Zone can be set to a distance between .01 and 2 nautical miles.

• Time To Safe Zone— sounds an alarm if MARPA determines that a target will intersect the Own Vessel Safe Zone within the defined time interval. The time interval settings range from 3 to 24 minutes.

• Safe Zone Ring—displays a ring on the Radar Page depicting the Own Vessel Safe Zone.

• Velocity Reference—has two settings, Absolute and Relative. This setting determines how speed and direction are displayed on the MARPA list. Relative calculates target speed and direction relative to your own. Absolute shows the target's actual speed.
