Setup Instructions
AUTO frequency
If the frequency is set to AUTO, one of the two single
frequencies (200 or 50 kHz) will be automatically selected,
depending on the depth of the bottom. If the bottom is
deeper than 350 feet (or 60 fathoms or 100 meters), the
unit will use the 50kHz frequency. In shallower water, the
unit will use the 200 kHz frequency.
MAN (Manual) frequency
You can also set the frequency manually. When you
choose Frequency MAN, the cursor will jump down to the
next line and wait for you to choose a frequency. Use the
< and > controls on the Page Control Pad to choose one of
the following five frequency selections:
•200 kHz, single frequency – The unit will use only the
narrow 200 kHz beam. If the fish symbols are enabled (in
the System Setup Menu), they will appear solid.
•50 kHz, single frequency – The unit will use the wider 50
kHz beam. If the fish symbols are enabled (in the System
Setup Menu), they will appear hollow.
•200 kHz, dual frequency – The presentation of the bottom
image and fish targets is the same as with the single 200
kHz frequency. If fish symbols are turned on in the System
Setup Menu, then they are displayed using the signal from
the 200 kHz beam (solid symbols) as well as from the 50
kHz beam (hollow symbols).
•50 kHz dual frequency – The presentation of the bottom
image and fish targets is the same as with the single 50
kHz frequency. If fish symbols are turned on in the System
Setup Menu, then fish symbols are displayed using the
signal from the 200 kHz beam (solid symbols) as well as
from the 50kHz beam (hollow symbols).
•Split – The full image from both frequencies is shown at
the same time. The 200 kHz display appears on the top
half of the screen, and the 50 kHz display appears on the
bottom half of the screen.
