1.Never set the same HOST NAME in the network.
2.The same Radar Source should be selected on the NavNet network. Never select different radar source on each Navnet or MaxSea unit if two radars and plotters are in the network.

Automatic Sounder Operation |
|
|
|
|
|
|
Two types of automatic sounder modes are available: |
|
|
|
CRUISING is for tracking the bottom, |
|
|
|
FISHING is for searching fish schools. |
|
|
CRUISING uses a higher clutter rejection setting than FISHING therefore it |
|
|
is not recommended for fish detection - weak fish echoes may be erased |
|
|
by the clutter suppression circuit. |

|
Automatic sounder operation is useful when you are preoccupied with |
|
|
other tasks and do not have the time to adjust the display. The automatic |
|
|
sounder function automatically selects the proper gain, range scale and |
|
|
clutter suppression level according to the depth. It works as follows: |
|
|
• The range changes automatically to locate the bottom on the lower half of |
|
|
the screen. The range jumps to one step shallower range when the bottom |
|
|
echoes reach a half way point of the full scale from the top and to one step |
|
|
deeper range when they come to the lower edge of the scale. |
|
|
• The gain is automatically adjusted to display the bottom echo in reddish |
|
|
brown (default color arrangement). |
|
|
• Clutter, which suppresses low level noise, is automatically adjusted. |
|
|
Manual Sounder Operation |
|
|
|
Manual operation is useful for observing fish schools and bottom using a |
|
|
fixed gain setting. |
|
|
The gain, range and range shift functions used together give you the |
|
|
means to select the depth you can see on the screen. The basic range can |
|
|
be thought of as providing a “window” into the water column and range |
|
|
shifting as moving the “window” to the desired depth. |

ACK: Acknowledge
ACQ: Acquire, Acquisition
Activation: Process that grants access to the software.The user submits first his Site Code and Serial number and then receives a custom Site Key.
Activation Wizard: The Activation Wizard makes the software activation easier providing a user friendly interface made of windows and forms.Activation can be automated (trough the Internet), delayed (by automatic email or manual one) or totally manual.
Active leg: is a segment of the route which is currently followed.
Active route: If an autopilot is enabled, it will steer the boat along an active route, heading for each successive waypoint as it is activated.
Active Waypoint: The active waypoint or mark is the waypoint or mark towards which you are currently traveling. An active waypoint slowly flashes to make it stand out on your screen.
ADJ: Adjust, Adjustment
AFC: Automatic Frequency Control
AGC: Automatic Gain Control
AIS: Automatic Identification System
Alarm (XTE): Cross Track Error Alarm is activated when the boat has deviated from the desired path of travel. In certain areas, deviation from the route could put the vessel in danger. If you are using a route to travel from point to point, you can select an amount of cross track error allowable before an alarm will sound.

Autopilot: A self-steering device which attaches to a vessel's steering mechanism to control the vessel's bearing.
AUX: Auxiliary System/Function
AWD: Apparent Wind Direction. This is abbreviated as AWD. In order to overcome the effects of current and leeway, a vessel which is trying to reach a given waypoint may not be able to steer straight towards it. As a result, onboard wind direction measurements - the AWD - may not be the same as the True Wind Direction (TWD). Your product derives TWD from AWD by taking any bearing deviation into account.
AWS: Apparent Wind Speed - When the vessel is in motion, onboard wind speed measurements - the AWS - will differ from stationary measurements (True Wind Speed, or TWS). Your product derives TWS from AWS by taking the vessel's motion into account.
B
Bearing: a horizontal angle, measured from 0 to 90 degrees, fixing the direction of a line or direction of travel with respect to either a north or south direction.
Bench mark: a relatively permanent material object, natural or man-made, with a known elevation. A bench mark can be used as a reference point when navigating a route or in determining the elevation of nearby land features.
