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.

around the scanner is clear. The GMR 404/406 transmits a beam
approximately 12° above and below a line extending horizontally
