Indications on the single frequency display
Note 1: The water temperature display requires an appropriate water
temperature sensor. It can be turned on or off with TEMPERATURE
GRAPH on the SOUNDER menu.
Note 2: When using the vertically split plotter/sounder display with dual
frequency or zoom display, the depth scale for the left sounder screen is
not displayed. Further, a last digit on the depth may be overlapped by
the line which splits screens.
Selecting transmission frequency
The single frequency display shows either the LF (low frequency) picture or HF
(high frequency) picture. To select transmission frequency, press the FREQ
LF/HF soft key to select “LF” or “HF”.
