Radar Tab
The Radar tab contains setup options for the Radar Page. The Sonar Page appears
only if you have the Radar check box selected on the System tab. See the “Using
Radar” section on page 89 for more information.
Temp (Temperature) Tab
The Temp tab displays the water temperature log (if equipped with a temperature
sensing transducer or receiving NMEA Sonar temperature data). The chart reads
from right to left, so that the most recent temperature measured appears on the far
right side of the chart. The dotted grid lines within the chart indicate intervals in
the temperature scale and the duration of time.
Log and Graph Scale—sets the temperature range (in degrees) for the
log. Select Auto to have the unit automatically determine the best range,
or select a span of 2, 4, 6, 8, or 10 degrees. Use the Reset button in Auto
mode to reset the automatic range.
Log Duration
—sets how fast or slow the temperature log scrolls (the
shorter the time duration, the faster the temperature log scrolls). Select a
duration from 1 minute to 2.5 hours.
