setting configured for use in one radar mode may or may not be
applied to other radar modes or to the Radar overlay.
From a Radar screen or the Radar overlay, select Menu >

Gauges and Almanac Information
Gauges provide various information about the trip, engine,
environment, and wind, and are available on all chartplotter
models. Numbers, Compass, and Trip gauges are available on
all chartplotters. Wind and Environment gauges require valid
wind data from the NMEA 0183 or NMEA 2000 network. Engine
gauges require a connection to the NMEA 2000 network, so
they are not available on all chartplotter models.
The chartplotters also provide almanac information about tides,
currents, and the sun and moon, such as rise and set times.

route using the compass.

Customizing Engine Gauge and Fuel Gauge Limits
You can configure the upper and lower limits and the range of
desired standard operation of a gauge. When a value exceeds
the range of standard operation, the gauge becomes red.
NOTE: Not all options are available for all gauges.
1
From the engine gauges screen, select Menu > Gauge
Setup > Set Gauge Limits .
2
Select a gauge.
3 Select Gauge Limits > Custom > Edit Limits .

• To set the minimum value of the standard operating
range, select Rated Min. .
• To set the maximum value of the standard operating
range, select Rated Max. .
• To set the lower limit of the gauge lower than the rated
minimum, select Scale Min. .
• To set the upper limit of the gauge higher than the rated
maximum, select Scale Max. .
5
Select the limit value.
