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 >
Noise Rejection > Cross Talk Reject.

Measuring the Potential Front-of-Boat Offset
The front-of-boat offset compensates for the physical location of
the radar scanner on a boat, if the radar scanner does not align
with the bow-stern axis.
1
Using a magnetic compass, take an optical bearing of a
stationary target located within viewable range.
2
Measure the target bearing on the radar.
3
If the bearing deviation is more than +/- 1°, set the front-of-
boat offset.
Setting the Front-of-Boat Offset
Before you can set the front-of-boat offset, you must measure
the potential front-of-boat offset.
The front-of-boat offset setting configured for use in one radar
mode is applied to every other radar mode and to the Radar
overlay.

Gauges and Almanac Information

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.

Viewing the Compass

You can view information about your bearing, heading, and
route using the compass.
Select Gauges > Compass.

Viewing Trip Gauges

Trip gauges show information for odometer, speed, time, and
fuel for your present trip.
Select Gauges > Trip Data.

Resetting Trip Gauges

1
Select Gauges > Trip Data > Menu.
2
Select an option:
• To set all the readings for the present trip to zero, select
Reset Trip.
• To set the maximum speed reading to zero, select Reset
Maximum Speed.
• To set the odometer reading to zero, select Reset
Odometer.
• To set all the readings to zero, select Reset All.

Viewing Engine and Fuel Gauges

Before you can view engine and fuel gauges, you must be
connected to a NMEA 2000 network capable of sensing engine
and fuel data. See the installation instructions for details.
Select Gauges > Engine.

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.
4
Select an option:
• 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.
6
Repeat steps 4 and 5 to set additional gauge limits.

Enabling Status Alarms for Engine Gauges

You can enable the chartplotter to display engine status alarms.
From the engine gauges screen, select Menu > Gauge
