CommercialRadar going to stand-by mode
Question
Why does my Furuno radar transmit for about 30 seconds, beep, and then go into stand-by mode for 5 minutes?
Solution
It sounds like you have the Watchman mode turned on. The Watchman mode sets the radar to stand-by and then transmits the radar at a user selected interval to check for target changes in the Guard Zone. If any changes occur, the radar will sound an audible alarm, cancel the Watchman mode and continue to transmit. Please refer to your operator's manual for instructions on turning this mode off.
Most Furuno radars will have a notation of [Watchman] on the display when the function is active and the display will beep when going into or out of this mode.
