Garmin GMR 21 - Manual (Page 6)

2 GMR 21/41 Owner’s Manual
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 21/41 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 21/41 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.
