Operation Manual

CZone™: Sets the digital switching circuits.
System Profiles: Allows you to save your system profile to a
memory card and import system profile settings from a
memory card. This can be helpful for charter or fleet vessels,
and for sharing your setup information with a friend.
Setting the Keel Offset
You can enter a keel offset to compensate the surface reading
for the depth of a keel, making it possible to measure depth from
the bottom of the keel instead of from the transducer location.
Enter a positive number to offset for a keel. You can enter a
negative number to compensate for a large vessel that may
draw several feet of water.
1
Complete an action, based on the location of the transducer:
If the transducer is installed at the water line
À
, measure
the distance from the transducer location to the keel of the
boat. Enter this value in steps 3 and 4 as a positive
number.
If the transducer is installed at the bottom of the keel
Á
,
measure the distance from the transducer to the water
line. Enter this value in steps 3 and 4 as a negative
number.
2
Select Settings > My Vessel > Depth and Anchoring >
Keel Offset.
3
Select or based on the location of the transducer.
4
Enter the distance measured in step 1.
Setting the Water Temperature Offset
Before you can set the water temperature offset, you must have
a NMEA 0183 water-temperature sensor or a temperature-
capable transducer to measure water temperature.
The temperature offset compensates for the temperature
reading from a temperature sensor.
1
Measure the water temperature using the temperature sensor
or temperature-capable transducer that is connected to the
chartplotter.
2
Measure the water temperature using a different temperature
sensor or a thermometer that is known to be accurate.
3
Subtract the water temperature measured in step 1 from the
water temperature measured in step 2.
This is the temperature offset. Enter this value in step 5 as a
positive number if the sensor connected to the chartplotter
measures the water temperature as being colder than it
actually is. Enter this value in step 5 as a negative number if
the sensor connected to the chartplotter measures the water
temperature as being warmer than it actually is.
4
Select Settings > My Vessel > Temp. Offset.
5
Enter the temperature offset calculated in step 3.
Calibrating a Water Speed Device
If you have a speed-sensing transducer connected to the
chartplotter, you can calibrate that speed-sensing device to
improve the accuracy of water-speed data displayed by the
chartplotter.
1
Select Settings
> My Vessel > Calibrate Water Speed
.
2
Follow the on-screen instructions.
If the boat is not moving fast enough or the speed sensor is
not registering a speed, a message appears.
3
Select OK
, and safely increase the boat speed.
4
If the message appears again, stop the boat, and ensure the
speed-sensor wheel is not stuck.
5
If the wheel turns freely, check the cable connections.
6
If you continue to get the message, contact Garmin product
support.
Other Vessels Settings
When your compatible chartplotter is connected to an AIS
device or VHF radio, you can set up how other vessels are
displayed on the chartplotter.
Select
Settings > Other Vessels.
AIS: Enables and disables AIS signal reception.
DSC: Enables and disables digital selective calling (DSC).
Collision Alarm: Sets the collision alarm (Setting the Safe-Zone
Collision Alarm,
page
7).
AIS-EPIRB Test: Enables test signals from Emergency Position
Indicating Radio Beacons (EPRIB).
AIS-MOB Test: Enables test signals from man overboard (MOB)
devices.
AIS-SART Test: Enables test transmissions from Search and
Rescue Transponders (SART).
