NAVMAN 8120/8084 Installation and Operation Manual

Warning

It is your sole responsibility to install and use the instrument and transducer(s) in a manner that will not cause accidents, personal injury or property damage. Always observe safe boating practices.

The choice, location, and installation of transducers and other components of the system are critical to the performance of the system as intended. If in doubt, consult your NAVMAN dealer.

To reduce the risk of misusing or misinterpreting this instrument, you must read and understand all aspects of this Installation and Operation Manual. We also recommend that you practice all operations using the built-in simulator before using this instrument at sea.

Global Positioning System: The Global Positioning System (GPS) is operated by the US Government which is solely responsible for its operation, accuracy and maintenance. The GPS is subject to changes which could affect the accuracy and performance of all GPS equipment anywhere in the world, including this instrument.

Electronic Chart: The electronic chart used by this instrument is an aid to navigation designed to supplement, not replace, official government charts. Only official government charts supplemented by notices to mariners contain the information required for safe

and prudent navigation. Always supplement the electronic information provided by this instrument with other plotting sources such as observations, depth soundings, radar and hand compass bearings. Should the information not agree, the discrepancy must be resolved before proceeding any further.

AIS: The AIS features on this chart-plotter are designed as a safety aid only and do not guarantee safety at sea. AIS transmission is mandatory on some, but not all, vessels. You should check your local laws and regulations for requirements in your area. As a result of different legal requirements, different vessel sizes and uses, you should not assume that your AIS equipped chart-plotter will show the location of ALL vessels in your area. Careful prudence, judgement, and safe navigation practices should always be exercised. AIS should be used to complement radar, but AIS is not a substitute for radar.

Sonar performance: The accuracy of the sonar depth display can be affected by many factors, including the type and location of the transducer and water conditions. Never use this instrument to gauge depth or other conditions for swimming or diving.

Fuel data: Do not rely on this instrument as the sole source of information about fuel available onboard. You must supplement this instrument’s fuel data with visual or other checks of the fuel available. This is necessary because possible operator errors, such as forgetting to reset the fuel used when filling the tank or running the engine with this instrument not switched on, can render this instrument inaccurate. Fuel economy can change drastically depending on boat loading and sea conditions. Always carry adequate fuel onboard for the intended trip, plus a reserve to allow for unforeseen circumstances.

Simulate mode: Never have simulate mode on when you are navigating on the water.

Failure to adhere to these warnings may lead to death, serious injury or property damage. NAVMAN disclaims all liability for installation or use of this product that causes or contributes to death, injury or property damage or that violates any law.

1-1 Overview

The NAVMAN 8120/8084 is a rugged, highly integrated marine chartplotter and fishfinder. It is easy to use and has a high resolution color display. Complex functions can be performed with only a few key presses, taking the hard work out of boating.

The available functions depend on the optional sensors and instruments that are installed:

The Video window requires the 8120/8084 to receive video from a compatible source, such as a camera.

Fuel functions require one or more petrol/gasoline or diesel fuel sensors to be installed.

SmartCraft engine functions require a SmartCraft system to be installed. For information on using SmartCraft, see the SmartCraft Gateway Installation and Operation Manual.

•DSC/Buddy track functions require an appropriate NAVMAN DSC VHF radio to be installed.

The 8120/8084 can send data to other instruments, such as an autopilot, and receive data from other instruments.

•Radar functions require an optional NAVMAN radar system to be installed. Three radar systems are available; 2 kW, 4 kW, or 6 kW.

•AIS functions require an optional AIS receiver to be installed.

For information on installation options, see section 20.

This manual describes how to install and operate the 8120/8084. Special terms are explained in Appendix C. For more information on this instrument and other NAVMAN products, go to our website, www.navman.com.

1-2 Cleaning and maintenance

The Instrument screen is covered by a proprietary anti-reflection coating. To avoid damage, clean the screen only with a damp cloth and mild detergent when dirty or covered in sea salt. Avoid abrasive cleaners, petrol or other solvents. If a plug-in card gets dirty or wet, clean it with a damp cloth or mild detergent.

Cover or remove a transom-mounted transducer when repainting the hull. If painting over a through hull transducer with

antifouling paint, use only one coat of paint. Remove the previous coat of antifouling paint by sanding it lightly.

To optimize performance, avoid walking on or jamming cables and connectors. Keep the transducer free of weed, paint and debris. Do not use a high pressure water blast on a speed sensor paddlewheel as it may damage the bearings.

Push the dust cover over the display when the Instrument is turned off.

Press the key which points in the direction that the cursor will move, for example press to move the cursor down.

Press midway between two of the cursor keys to make the cursor move diagonally.

Hold a cursor key down to make the cursor move continuously across the window.

In Cursor mode:

The distance (DST) and bearing (BRG) of the cursor from the boat are displayed at the bottom corner of the window.

The chart does not scroll as the boat moves.

If the cursor reaches the edge of the window, the chart will scroll.

For example, hold down to move the cursor to the right side of the window and the chart will scroll to the left.

3-2-2 Latitude and longitude

Latitude and longitude can be displayed in the data header. The window is degrees and minutes to three decimal places, about 2 m (6 ft) resolution. Normally the position is the

boat’s position, and the latitude and longitude has a boat symbol to show this:

36° 29.637’	N or S	Latitude
175° 09.165’	E or W	Longitude

If the cursor has been moved in the last ten seconds, then the position is the cursor’s

position, and the latitude and longitude has a cursor symbol to show this:

36° 29.841’	N or S	Latitude
175° 09.012’	E or W	Longitude

! WARNING

When reading the boat position, make sure the position is not the cursor position.

A	Projected position	A
A	Projected position
B	Boat’s projected course	B
C	Boat position

3-5 Tracks and tracking

Tracking records the boat’s position to memory at regular intervals, which can be:

Time intervals.

Or distance intervals.

The track of where the boat has been can be displayed on the chart. The Instrument can display one track while recording another.

To work with tracks, see section 19-7.

The Instrument can store five tracks:

Track 1 can hold up to 2000 points and is intended to record the normal progress of the boat.

Tracks 2, 3, 4 and 5 can hold up to 500 points each and are intended to record sections to be retraced accurately, for example entering a river mouth.

Tip: Record a reference tracks and then use the track to help navigate the same trip later. For example, record a reference track as you leave harbour. Then if you return to harbour and visibility is poor, select the chart and navigate manually along the reference track back into the harbour. Record reference tracks in good conditions.

When recording is on and the track becomes full then recording continues and the oldest points in the track are deleted. The maximum length of a track depends on the selected track interval: a small interval will give a shorter, more detailed track and a long interval will

give a longer, less detailed track, as shown in these examples:

Time intervals

Interval	Track 1		Track 2, 3, 4 or 5
1 sec	33	minutes	8	minutes
10 sec	5.5	hours	1.4	hours
1 min	33	hours	8	hours
Distance intervals
Interval	Track 1		Track 2, 3, 4 or 5

0.01	20		5
1	2,000		500
10	20,000		5,000

The track lengths are in the current distance units, for example nm.
