The innovative technology uses so little current and the power supply is so efficient, that the display is independent from your boat's batteries. Wireless: your Tactick displays communicate by wireless, they can be sited anywhere on your boat without disruption or cables. Dedicated to Performance Optimise your start: the Dual Maxi Display's powerful functions for Distance and Speed-Trim to the line, Line Bias and Race Timer help you get the best possible start. Enhance your performance with the built-in functions for Wind Shift, Velocity Made Good and Tack Course Simplify your tidal navigation with the Dual Maxi Display's Set, Drift, Turn and Course to Steer functions. Easy to Manage Automatic data selection: the innovative Auto Leg function allows the display to automatically show the information you need for each leg of the course. Page Hiding means you can avoid data duplication on different displays, minimising the time to select the pages you really need. Wireless Remote control: your Dual Maxi display can be controlled and configured from anywhere in the boat using a Tacktick Remote display. Excellent visibility The large, high contrast LCD gives the Dual Maxi Display a wide angle of view and ensures excellent visibility from anywhere on your boat. Two panes with 35mm digits maximise the information available. The black background minimises disturbance to your night vision, and the red/amber option allows you to choose the backlight colour of your display at night. 2 www.tacktick.com System Overview 2 System Overview Important: Ensure that the "Auto Network" procedure described on the yellow instruction sheet and full Setup and Calibration has been performed correctly before attempting to use your Micronet system. Display Features 2.1 2.2

, or Remote Control Your Dual Maxi Display is designed to be controlled and configured using a Tacktick Remote Display. See the user guide supplied with the Remote Display for details of using the Remote Display in remote control mode. All references in this user guide to the buttons refer to the appropriate button on the Remote Display. Upper and Lower Panes The upper and lower panes of the Dual Maxi Display function independently; each pane acts as a separate display and can be configured separately. When a Dual Maxi Display is selected using the button of the Remote Display, the upper pane of the Dual Maxi will flash, indicating that it is selected for remote control. A further press of the button will cause the lower pane of the Dual Maxi to flash, indicating that this pane is now selected for remote control. Note: If a Remote Display is not available, the single control button provides a limited control capability, see page 16 for details. Note: for configuration of the Dual Maxi Display a Remote Display is required. See page 18 for details of configuring your Dual Maxi Display. 3 Dual Maxi Display 2.3 2.4 2.5 Switching the System On and Off To switch your Micronet system on or off select any display and press the button for 2 seconds. (See page 16 for use of the Dual Maxi Display control button) Chapter and Page operation Data is shown on the panes of the Dual Maxi Display in Chapters, each containing several pages of related data. The diagram on page 13 shows the full set of chapters and data pages available. For a detailed description of individual data items supported on the Micronet network, see the Micronet Data user guide on your product CD or on the Tacktick web site. and to move to scroll through the chapters and Selecting Chapters and Pages:

Both Chapter and Page selection will scroll back to the first page once a cycle has been completed. Pages for which no data is available are displayed as dashes (- - -) Power Management and Battery Life What makes your Dual Maxi display possible is Tacktick's revolutionary approach to power management. By reducing the amount of power being used by the electronics and dual Maximizing the potential of the sun to provide power, the Dual Maxi display becomes a virtually perpetual device. Power status is indicated by two icons on the display:

Battery Level Used together these icons will show the condition of the power supply. Note: If the internal battery is fully charged then it does not matter how much the display is subjected to bright sunlight no further charging is required and the Charge Rate Indicator will remain low. Charge Rate and 4 www.tacktick.com System Overview If the displays are to be stored for a long period of time before next use

(Over Winter) ensure that the batteries are fully charged before storage. If necessary connect to a 9 to 30V DC power supply for 24 hrs prior to storage, using the external power leads. Warning: Artificial light WILL NOT recharge the battery. Placing your Dual Maxi Display close to an artificial light will seriously damage the display. Only recharge in natural daylight. Backlighting At any stage of the display's operation press and hold seconds to access the lighting control. for two 2.6 and will scroll through setting OFF, 1, 2 Pressing and 3 whilst changing the backlighting. If using the displays at night, power usage can be reduced dramatically by switching the Backlighting to level 1 or 2. To save power, it is recommended that backlighting Level 3 is used only in dusk conditions. The Dual Maxi Display can be configured to use either red or amber backlighting (see page 23). Tacktick recommend that red backlighting is used whenever possible as this uses less battery power. Backlighting is automatically switched off in daylight as part of the display's power saving feature and will not operate in daylight. www.tacktick.com 5 Dual Maxi Display 2.7 Sleep Mode If there is no boat speed or change in heading registered on the system for a period of 12 hours your Dual Maxi display will switch off to conserve power. A "POWER SAVE" alarm will sound before the system switches off. Pressing any button within 10 seconds of the alarm sounding will allow the system to remain switched on. 6 www.tacktick.com Performance Functions 3 3.1 Performance Functions Automatic Pages You probably want different pages shown on your Dual Maxi Display for each leg of the course. The Dual Maxi display makes this easy by providing a special page: the AUTO LEG page. Using this feature, you can programme your Dual Maxi to show exactly the information you require for each leg of the course without the need to manually change pages at each mark rounding. For example, consider a boat with two Dual Maxi Displays on a mast bracket. It may be decided that during the start the data required is Boat Speed, Depart, Line Bias and Race Timer; for the windward leg Boat Speed, Heading, VMG to Windward and Wind Shift; and downwind Boat Speed, Heading, VMG to Waypoint and True Wind Direction. Programming these pages into the Autoleg Page prior to the race would automatically show these pages for the appropriate leg of the course;

leaving the tactician free to concentrate on the race, not on configuring his instruments. The legs and the pages displayed can be configured in setup to meet your specific needs, see page 20. Similarly, using the Page Hiding function to eliminate duplicate pages across the three displays reduces the time and key presses required if a manual reconfiguration of the data displayed becomes necessary. Note: It is a good idea to programme the remote control display list of your Remote Display to show your displays in the same order as their physical location on the boat. See the Remote Display user guide. www.tacktick.com 7 Dual Maxi Display 3.2 Optimising your start The Dual Maxi display has three functions to help you get a great start:

The Depart page shows your distance from the start line and how much faster (or slower) you must sail to hit the line at the start signal. The Race Timer gives you a visual and audible count down. The Line Bias page helps you choose the best position on the line. Using the Depart page Approaching the start, it is vital to know your distance from the line and whether you will arrive before or after the signal. The large digits show your distance from the nearest point on the line in distance units or boat-lengths (see page 23). Note: A negative distance shows that the boat is to windward of the start line, not that the boat is on the course side of the line; i.e. for a downwind start, a negative distance shows you are approaching the line correctly. The small digits show the change in speed required for you to arrive at the line at the signal; a negative value means that you must decrease your speed to avoid arriving early. Warning: These calculations rely on GPS data, so they are subject to error, particularly as the distance from the line becomes small. Do not rely on this information to determine if you are over the line at the start. Rather, you should use the data to help optimise your approach to the line. Note: Before using the Depart function, you must configure the Boat Length and GPS Bow parameters in setup; see page 22. Initialising the Depart page With the depart page displayed, approach one end of the start line as if starting; press when the bow touches the line. A popup page shows that the first line position has been captured. Repeat at the other end of the line. The popup shows the second line position has been captured. 8 www.tacktick.com Performance Functions Note: The line for Depart calculations is between the positions you set. Set your points as close to the ends of the actual start line as possible. Modifying the start line points If it is necessary to modify one of the points, press while at the correct location; the popup will show that position 1 has been captured. Pressing while the popup is visible will allow you to set the captured location to position 2. or to discard it (-). or Note: the position is captured at the moment is pressed. Starting and Start Line Bias When the starting line is laid at exactly right angles to the wind, the distance sailed to the windward mark is the same wherever the boat starts on the start line. In real racing there is often a favoured end to the line. If you start at the favoured end, you are upwind and therefore ahead of a boat starting at the other end of the line. The larger the Line Bias angle, the more you can gain from starting at the favoured end of the line. The diagram shows how this works in practice. Your Dual Maxi Display can calculate and display the Line Bias angle and the favoured end of the line. To initialise the line bias display Go to the Line Bias page, Sail directly along the start line, then press

. The Line Bias angle and the favoured end of the start line are displayed. The line bias display is continually updated taking account of wind shifts that may occur during the pre-start period. Using the Start Timer The most convenient way to operate the race timer is to use the Timer Page of the Remote Display. Once started the countdown is available on all displays. See the Remote Display user guide for details of operating the race timer. www.tacktick.com 9 Dual Maxi Display 3.3 During the Race Sailing upwind. VMG to Windward To get to the windward mark as quickly as possible it is necessary to balance pointing angle against boat speed to maximise the speed directly towards the wind (this speed is called the Velocity Made Good to Windward). The Dual Maxi Display automatically calculates your VMG to windward. Wind Shift Like most things in sailing, the wind does not remain constant in either strength or direction. Every shift in the wind requires the boat to alter its heading in order to maintain a close hauled course. A shift that allows the boat to change its heading closer to the Mean Wind Direction is called a "lift"; a shift that forces the boat to change course away from the Mean Wind Direction is known as a "header". In an oscillating wind, a boat that regularly tacks when headed will spend more of its time sailing a lifted course and will sail a shorter distance to the windward mark than a boat that regularly sails a headed course. This gives the boat sailing in the lifts a considerable advantage. In the diagram, the boat on the right sails a shorter course by tacking when headed and thereby sailing mostly in lifts. The system automatically calculates the mean wind direction by averaging the true wind direction over a period of time Sail your boat for dual Maximum speed and use the Dual Maxi Display to identify the headers and lifts to help you decide when to tack or gybe. Permanent wind shifts can be recognised as a constant header on one tack, and a constant lift on the other tack. In this situation, you can reset the mean wind direction as follows:

10 www.tacktick.com Performance Functions 1. Go to the Wind Shift page 2. Press Direction.

, the mean wind direction is reset to the current True Wind 3. The new value is displayed; if required, it may be adjusted using and

. Note: resetting the mean wind direction manually disables averaging until the system is switched off. Sailing Downwind Sailing downwind, it is rarely fastest to aim directly for the mark. Usually it is better to sail at a higher angle to increase boat speed and gybe as necessary to reach the mark. The increase in speed can more than compensate for the additional distance sailed. In technical terms, you aim to dual Maximise your VMG (Velocity Made Good) towards the mark. Use VMG-WP (VMG to Waypoint) together with the True Wind Angle to optimise your VMG to the downwind mark Use the SHIFT page to help you time your gybes. Aim to gybe on lifts, to keep sailing on the headed tack. Sailing in Tidal Waters When you are sailing in tidal conditions, your boat's actual Course Over the Ground (COG) and Speed Over the Ground (SOG) may differ considerably from the heading of the boat and the speed through the water shown by the speed sensor. The Dual Maxi Display provides the following functions to make your tidal navigation easier. Turn When steering towards a waypoint in tidal conditions, it is often difficult to assess the course to steer to keep on the direct the mark. Your Dual Maxi Display automatically indicates when the course you are steering is taking you off the direct track to your waypoint. The direction and required angle of turn is displayed. track to www.tacktick.com 11 Dual Maxi Display Course Used in similar circumstances to the Turn page, the Course page shows the course to steer to track directly to the waypoint. Drift and Set Because the boat is not always moving directly in the direction of its compass heading you need to know the direction (SET) and the speed (DRIFT) by which the boat is being pushed off course. Tactically this is important when assessing when to tack or gybe to round a mark or clear an obstruction or headland. Your Dual Maxi Display automatically calculates this information using information from your GPS, boat speed and compass. The calculated set angle is rounded to the nearest ten degrees. Note: Set and Drift as calculated includes the effect of both tide and leeway. Therefore the value will be different on opposite tacks, depending on whether the boat is sailing into or against the tide. This will be especially noticeable when the tidal effect is small. Warning: In conditions of little tide, this calculation is very sensitive to inaccuracies in the calibration of your speed and compass transducers. It is not recommended that you rely on the accuracy of this calculation in situations where the tide speed is less than one Knot Note: A flashing indicator will alert you if the calculated values are uncertain). See Sea Trial and Calibration on page 25 for information on how to maximise the accuracy of the calibration of your speed and heading transducers. 12 www.tacktick.com 4 4.1 Operation Data Chapters and Pages Operation www.tacktick.com 13 Dual Maxi Display 4.2 Audible Signals and Alarms At stages during its operation your Dual Maxi Display will beep to indicate alarms or moments of importance.

Warning: It is not safe to use the displays for navigational purposes until Calibration has been carried out correctly. Warning: Accurate calibration is essential for successful use of the Dual Maxi Displays advanced functions. In particular, the calculation of Set and Drift is sensitive to errors in the measured boat speed and the compass heading and deviation. To ensure the maximum accuracy, calibration must be carried out with great care. Note: System calibration cannot be carried out using the Dual Maxi Display, use a Remote Display for this purpose. Refer to the Remote Display user guide for the system calibration procedure. To check the accuracy of your calibration, carry out the following tests:

Speed:

Run directly into and against the current; you should see the difference between SOG and SPEED to reverse (eg SOG 6.5 and SPEED 6 running with the current and SOG 5.5 and SPEED 6 directly into the current would indicate a good calibration). Compass:

In slack water with no wind, COG and HDG should match on all four compass points (i.e. when steering a steady course North, East, South and West). If either SPEED or HEADING does not pass this test, refer to the Remote Display user guide and perform the following calibrations:

Remote user guide - Speed Calibration

perform a log calibration Remote user guide - Compass Calibration and Alignment

carry out a compass deviation turn align the heading Remote user guide Setup - Magnetic Variation If your GPS is not providing Magnetic Variation data, manually set

the local Magnetic Variation. www.tacktick.com 25 Dual Maxi Display 7 Installation Your Dual Maxi Display may be mounted on a Tacktick Mast Bracket or directly onto a bulkhead. External Power In cases where displays are mounted permanently below decks it will be necessary to apply an external power source to prevent complete discharge of the built in battery. Connections on the rear of the display allow a 9V to 30V DC power source to be connected. Connections can be made to the vessels DC system or to a 9V battery pack. It is recommended that permanent connection is only made when the display is permanently fixed to the vessel and not when a removable bracket is used. Connection to a 9V (PP3) battery will fully recharge the internal battery over a period of 24 hours. Bracket mounting Warning: Tacktick recommend the use of a Tacktick supplied bracket, which is designed to optimise the radio reception of the Dual Maxi Display. Please refer to the installation instructions provided with the bracket. If using a customised bracket, you should avoid the use of conducting material (e.g Aluminium, Carbon Fibre, etc). If this is not possible, you must provide the maximum cut-out area behind each Dual Maxi Display to allow free circulation around the antenna. See the mounting template for details of the cutout required. If in doubt, refer to www.tacktick.com. Bulkhead mounting Warning: If installing your Dual Maxi Display on a carbon fibre or metal bulkhead, it may be necessary to make a cutout to ensure adequate radio circulation around the antenna. Refer to the mounting template for details of the cutout required. If in doubt, refer to www.tacktick.com. Use the template provided to select a suitable position for mounting. Ensure the mounting surface is flat. Leave space between displays for sun covers. Avoid areas where damage may occur (winch handles, feet, warps etc.) Check for clarity of vision and ease of access to the control button. 7.1 7.2 26 www.tacktick.com Installation Where there is no access to the rear of the mounting surface Warning: only use the screws provided with the display and take care not to over tighten the screws. Incorrect or overtightened screws may cause the moulding to crack; this will invalidate your warranty. Position the supplied Template carefully before starting. 1. Drill four 2.5mm holes as marked on the template. 2. Refer to the diagram below. Using your fingers, carefully snap the facia of the display off the main body by pulling in the direction of the arrows. Warning: take care not to drop the button pad. 3. Remove the four captive M4 nuts from the plastic moulding and attach the display to the mounting surface using the four self tapping screws provided. 4. Check the display is perfectly level; carefully position the button insert into the slot and snap the facia back into position. Where access is available to the rear of the mounting surface Warning: do not bolt through from the front or replace the plastic nuts with metal nuts. This may cause the moulding to crack and will invalidate your warranty. This method allows for maximum security of a permanently mounted display.

Any DC voltage between 9 and 30V is sufficient to power the Hull Transmitter and Wireless (NMEA) Interface. www.tacktick.com 29 Dual Maxi Display Power Save Alarm sounds There has been no significant data activity on the network. The alarm sounds to indicate that the display system will turn itself off. To continue using the system press any button to cancel the alarm. Lost Network Alarm sounds This indicates that one or more displays have lost communication with the Master*. Either there is a problem with the Master* display or the displays in question have been moved out of effective range. The displays will switch off after sounding the alarm to save power. Note: * The "Master display" is the display used to power up the entire system. This may be different each time the system is used. If you are uncertain which display is the master, switch off the system and switch on again. The display which you switched on is now the Master. A single display flashes the battery symbol and then switches off The battery level is low on the particular display affected. Connect to a 9 to 30V DC power source or leave in bright sunlight for 12 hours minimum to recharge the display's internal battery. If the particular display is the system Master* then the other displays will sound the "Lost Network"

alarm. To continue using the rest of the system power down and restart the system from another display. Low Battery Alarm sounds The power level is low in the Hull Transmitter, Wireless (NMEA) Interface or Wind Transmitter. Enter Setup mode on the Remote Display and scroll to the Health Chapter. Check the battery levels of the Transmitters and Interface Box. The battery level icon should show 1, 2 or 3 bars to ensure correct operation. Connect the Hull Transmitter or Wireless (NMEA) Interface to a 9 to 30V DC power source for 12 hours minimum to recharge the internal battery. Leave the Wind Transmitter in bright sunlight for 12 hours minimum to recharge its internal battery. Data is shown as dashes The information is not being transmitted to the displays. There may be lost communication between the Wind Transmitter or Hull Transmitter and the displays. Enter Setup mode on the Remote Display and scroll to the Health Chapter. Check the signal levels of the Hull and Wind Transmitters. The signal level should show a value greater than 3 to ensure correct operation. 30 www.tacktick.com Maintenance and Fault Finding Boat Speed reads 0 Information being transmitted from the Hull Transmitter is being received with a zero value. Check the paddle wheel for fouling, clean it and make sure it turns easily. Wind Speed reads 0 Information being transmitted from the Wind Transmitter is being received with a zero value. If the anemometer cups at the top of the mast are turning and the wind speed reads zero then there is a problem with your Wind Transmitter. No NMEA data showing on external displays Enter Setup mode on the remote display and scroll to the Health Chapter. Check the signal level and battery status of the Wireless

(NMEA) Interface. If the signal level shows a value greater than 3 then check the data connections and the settings of the NMEA equipment to ensure that NMEA 0183 is being transmitted correctly. The Depth Alarm does not sound If the actual water depth is shallow and the alarm has not sounded it is most likely that the alarm is switched off. Enter Setup mode on the Remote Display and scroll to the Depth Chapter. Ensure the Depth Alarm settings are correct. Compass information displayed on the system does not agree with the main steering compass. Ensure that the main steering compass has been swung correctly and is showing correct information. Ensure that the Compass Calibration procedure has been correctly completed (see the Remote Display user guide). If there are still differences, look for magnetic objects (loud speakers, pumps and motors, etc.) close to the Compass Transducer and try mounting the transducer in an alternative location. After changing position of nearby equipment or the Compass Transducer it will be necessary to re-calibrate the compass. www.tacktick.com 31 Dual Maxi Display Specifications Height of main digits: 35 mm (2") Backlighting:
