Power save function

The power save function conserves the boat's battery
power by pausing the transmission. The standby
(pausing) times are selectable (*rotation number is
fixed on 10 rotations).
For example, when 1 min. is selected, the scanner ro-
tates 10 revolutions; then stops for 1 min., and then re-
peats this sequence while the power save function is
activated.
