■ 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 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.
D Setting the scanning standby time
q Push [MENU]/[ ] four times to call up the INT.
SETTING menu.
w Push [Ú] until the “SAVE TIME” section becomes
highlighted.
e Push [Ω ≈] to select standby time.
•1, 6, 15, and 30 min. are available.
r Push [MENU]/[ ] twice to exit the menu display.
D Using the power save function
q Push and hold [TX (SAVE)]/[ ] for 1 sec. to
turn the power save function ON.
•The save indicator appears in the top of the screen.
w After the scanning rotations are finished, transmis-
sion and rotation are suspended until the selected
standby time elapses.
•The display shows the last scanned echoes until the
scanning restarts.
•“SAVE” and standby time appear in the top of the screen
and the standby time is counted down.
e After the selected standby time elapses, transmis-
sion and rotation restart.
r Push [TX (SAVE)]/[ ] to cancel the power
save function.

NOTE: When you use the power save function to-
gether with the alarm function, the CRT display is
turned OFF until an object enters the programmed
alarm zone, therefore, more power saving is possi-
ble. (p. 17)
