Radar modes
There are four radar modes:
• Disabled. This saves on power
consumption and magnetron usage. If the
radar is disabled, it has to warm up and
enter standby mode before it can start
transmitting.
• Warming. The radar on and is warming up.
This can take up to 90 seconds, depending
on your scanner type.
• Standby. The radar is on and is warmed
up. It is ready to start transmitting
immediately.
• Transmitting. The radar is actively sending
and receiving microwave radio pulses. An
open array will be rotating.
If you want to save on power but be able to
start transmitting immediately, use standby
mode.
