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.

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 is a rugged, highly integrated marine chartplotter and fishfinder. It is easy to use and has a very large, easy

to read and use colour 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 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 can send data to other instruments, such as an autopilot, and receive data from other instruments.

For information on installation options, see section 18-2.

This manual describes how to install and operate the 8120. 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.

6	8120 Installation and Operation Manual

1-3 Plug-in cards

The 8120 can use two kinds of C-MAP™ SD-Card plug-in cards:

Chart cards have chart details required for navigating in a particular region. When you insert a chart card, the extra details automatically appear on the Chart window. You can plug in up to two chart cards at once. If the chart shows a region not covered by a chart card, then it displays a simplified built-in world chart.

User cards store navigation data. A user card allows navigation data to be transferred to another compatible instrument (see section 14).

CAUTION

Handle plug-in cards carefully. Keep them in their protective cases when not plugged into the 8120.

Keep the 8120 card cover closed at all times to prevent moisture from entering the card compartment.

The Instrument stops navigating to the waypoint at the end of the current leg and starts the next leg of the route:

1When the boat comes within 0.025 nm of the waypoint

2 Or when the boat passes the waypoint

3 Or if you skip the waypoint.

Skipping a waypoint

To skip a waypoint, go to a chart window, press MENU and select Skip. The Instrument starts navigating straight towards the next waypoint on the route.

! CAUTION

Skipping a waypoint with the autopilot on might result in a sudden course change.

Cancelling a route

When the boat has reached the final waypoint, or to stop the boat following the

route at any time, cancel the route. Go to a chart window, press MENU and select Cancel route.

3-2-1 Chart modes

The Chart has two modes:

Centre on boat mode

To switch to centre on boat mode in the chart window, press ESC . The boatis at the centre of the chart. As the boat moves through the water, the chart automatically scrolls to keep the boat in the centre of the chart. The cursor (see below) is turned off.

Cursor mode

The keysandare called cursor keys. To switch to cursor mode in the chart window, hold down a cursor key. The cursor appears and moves away from the boat:

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 downto 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.

3-5 Tracks and tracking

A

B

C

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 17-6. 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
