[. . . ] 0 1 2 Introduction Thank you for choosing FI-30 Wind Data instrument. We are convinced that you will appreciate all the valuable information either you are a cruiser or a racer. It is important that you are following this instruction regarding installation and operation. If the instrument are to be used in a Nexus Network, there are some systems settings that are dependent on where the transducers are installed, i. e. [. . . ] The steer reference [CTS] is automatically calculated. Even if your Compass is un-deviated, the CTS function will anyway tell you the optimum course to sail !The CTS function gives you the shortest way to sail towards the Waypoint. Tide must however be taken into consideration, since it will give a time dependant drift on the boat. 20 4. 5. 7 Tactical use of [MEM] Function [MEM] is used to discover the smallest of wind shifts during upwind or downwind sailing, but it is your tactical decision wheter to tac or to stay on course. The Compass Data instrument will automatically keep track on wheter you are using the starboard or port MEM if the course difference between each trim is more than 45°. There is also a new function called [KTR] (Knock TimeR), giving you the time spent i seconds when sailing below a preset "knock Angle". Both [MEM] and [KTR] will help you to get a very good "picture" over actual windshifts, both in size and time. On the optimum compass heading, press the trim or SET button to store your present course in the memory called MEM. Your actual course is then constantly compared with MEM and displayed as a lift or as a header. Each time you press trim or KEY, a new reference course is set. How to use the MEM function: When you are sailing at a good speed and with the sail trimmed, press trim or SET. The Compass Data will then store the present course in memory MEM as a reference. If you then have a lifter, press TRIM again, but if you have a header more then 5°-10°, tack. After you tack, re-trim the sails and get a good boat speed before you press trim or SET again. Now you have set a new reference in the memory. Whenever you get a lifter, press TRIM, but when you get a header, tack. Your previous trim reference will automatically be displayed and used. Now, add the KTR timer The timer must first be activated. This is done by setting the CAL value C-17 to the maximum angle where you consider your boat to be pushed off course, i. e. where you normally would tac when getting a header. 4. 5. 8 Battery voltage [BAT] The text [BAT] will display battery voltage. The voltage is measured inside the instrument and will not compensate for any voltage drop caused by installation. [. . . ] · Make sure the Autodeviation have been carried out.
