Garmin gmr 41 Manuale Utente

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.
