Setting The Bow Offset; Calibrating The Compass; Radar; Radar Interpretation - Garmin Volvo Penta Glass Cockpit B7 Owner's Manual

down view transducers are installed at a zero-degree
angle.
Flipped: Sets the orientation of the Panoptix sonar view
when the down view transducer is installed with the
cables pointing toward the port side of the boat.
This applies to Panoptix transducers in the LiveVü
Down, RealVü 3D Down, and RealVü 3D Historical
sonar views.
Calibrate Compass: Calibrates the internal compass in
the Panoptix transducer
page 45).
This applies to Panoptix transducers with an internal
compass, such as the PS21-TR transducer.
Orientation: Controls if the transducer is in down or
forward installation mode. The Auto setting uses the
AHRS sensor to determine the orientation.
This applies to PS22 and LiveScope transducers.
Focus: Adjusts the sonar view to compensate for the
speed of sound in water. The Auto setting uses the
temperature of the water to calculate the speed of
sound.
This applies to LiveScope transducers.
Restore Sonar Defaults: Restores the sonar settings to
the factory default values.

Setting the Bow Offset

For forward view Panoptix transducers, you can enter a
bow offset to compensate the forward distance readings
for the transducer installation location. This allows you to
view the forward distance from the bow instead of the
transducer installation location.
This feature applies to Panoptix transducers in the
FrontVü, LiveVü Forward, and RealVü 3D Forward sonar
views.
1 Measure the horizontal distance
transducer to the bow.
2 From an applicable sonar view, select Menu > Sonar
Setup > Installation > Bow Offset.
3 Enter the distance measured, and select Done.
On the applicable sonar view, the forward range shifts by
the distance you entered.

Calibrating the Compass

Before you can calibrate the compass, the transducer
must be installed on the shaft far enough away from the
trolling motor to avoid magnetic interference, and
deployed in the water. Calibration must be of sufficient
quality to enable the internal compass.
NOTE: To use the compass, you must mount the
transducer on the transom or the trolling motor shaft. The

Radar

(Calibrating the Compass,
from the
compass may not work when you mount the transducer
on the motor.
NOTE: For best results, you should use a heading sensor
such as the SteadyCast
sensor shows the direction the transducer is pointing
relative to the boat.
NOTE: Compass calibration is available only for
transducers with an internal compass, such as the PS21-
TR transducer.
You can begin turning your boat before calibrating, but
you must fully rotate your boat 1.5 times during
calibration.
1 From an applicable sonar view, select Menu > Sonar
Setup > Installation.
2 If necessary, select Use AHRS to turn on the AHRS
sensor.
3 Select Calibrate Compass.
4 Follow the on-screen instructions.
The marine radar transmits microwave energy that has
the potential to be harmful to humans and animals. Before
beginning radar transmission, verify that the area around
the radar is clear. The radar transmits a beam
approximately 12° above and below a line extending
horizontally from the center of the radar.
To avoid possible personal injury, do not look directly at
the antenna at close range when the radar is transmitting.
Eyes are the most sensitive part of the body to
electromagnetic energy.
When you connect your compatible chartplotter to an
optional Garmin marine radar, such as a GMR
6 radar or a GMR 24 xHD, you can view more information
about your surroundings.
The radar transmits a narrow beam of microwave energy
as it rotates to a 360° pattern. When the transmitted
energy contacts a target, some of that energy is reflected
back to the radar.

Radar Interpretation

Reading and interpreting the radar display takes practice.
The more you use the radar, the better you will become at
relying on the radar display when you really need it.
Radar can be useful in many situations, such as avoiding
collisions when you have limited visibility, for example
when it is dark or foggy, tracking weather, seeing what is
ahead of you, and locating birds and fish.
The radar overlay feature can help you interpret the radar
display more easily, because it overlays the radar returns
on top of the chart. This can help you identify the
difference between a radar return of a land mass, bridge,
or rain cloud. Showing the AIS vessels on the radar
overlay can also help you identify features on the radar
display.
