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 to 10).
For example, when 1 minute is selected, the scanner
rotates 10 revolutions; then stops for 1 minute, and
then repeats this sequence while the power save func-
tion is activated.
