Sonar Quick Reference
1. Mount the transducer, antenna and unit. Connect the unit to electric
power and the transducer (If GPS operation is desired, connect GPS
antenna, too.). Make sure the MMC is in (See complete installation
details beginning on page 9.).
2. Launch your boat.
3. To turn on the unit, press and release
PWR key.
4. Opening screen displays Map Page. Rotate through the four main
Page screens (Map Page, Satellite Status Page, Navigation Page, Sonar
Page) by pressing
PAGES|← or → to select Page Name|EXIT. Switch
Pages to display Sonar Page.
5. If GPS data is desired, wait while unit locates satellites and calculates
current position. When the unit acquires position, a tone will sound and a
position acquired message will appear.
6. With position acquired (if desired), head for your fishing grounds.
Your unit will automatically display digital depth and surface water
temperature in the top left corner of the screen.
The auto settings will track the bottom, displaying it in the lower
portion of the screen. The full sonar chart will scroll from right to left,
showing you what's under the boat as you cruise across the water. You
can change the display by:
Zooming in to enlarge the chart for more detail: press
ZIN.
Zooming out to return to full chart mode: press
ZOUT.
7. Watch the display for the appearance of fish arches. When you see
arches, you've found fish! Stop the boat and get your lure or bait into
the water at the depth indicated on the sonar chart.
8. Gauge the fish depth by visually comparing the fish arches with the
depth scale on the right side of the screen, or get a more accurate
measure with the Depth Cursor. Press
MENU|↓ to DEPTH CURSOR|ENT.
Press ↓ to align the cursor line with the fish arch. The exact depth
appears in a box at the right end of the cursor line. To clear the cursor,
press
EXIT.
9. If you are anchored or drifting at a very low speed, you are not
moving fast enough for a fish to return the telltale fish arch signal. As
you drift over a fish, or as a fish swims through the transducer's signal
cone, the fish echo will appear as a straight line suspended between the
surface and the bottom.
10. To turn off the unit, press and hold
PWR key for three seconds.
