First, in Standby the system is warmed up and ready to go but the antenna is
not radiating a signal or listening for a return. Because the antenna isn't
being used, there's less power used during Standby. Pressing the Transmit
button starts the antenna and power consumption is increased. The advantage
of Standby is that the system's ready to use when you want it.
Second, Watchman reduces power consumption by cycling the antenna off and
on. You set the length of the off period. If the antenna notices a change in
the returns from the previous on cycle, it stops the Watchman function and
continues to stay on. If you have the optional external alarm, it will be
sounded.

All that is true. The main draw for Standby Mode is keeping the
Magnitron (Transmitter tube) warmed up and ready for instant
operation. This requires about 7 Watts of power for a 2Kw
magnitron, and more as the PPP of the magnitron goes up. If
you can stand a 3 minute delay in using your radar, better to turn it
OFF, than use standby when Power consumtion is an issue.
