[. . . ] 00 M U LTI N S 31 Reference Manual and Installation Manual FCC Statement Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a normal installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. [. . . ] The distance travelled since total log was reset: The log units are NM, KM or M (miles) and correspond to the speed units, for example if you set the speed units to KPH then the log units are KM (see section 3-1). Total log 4-1 Reset log Resetting zeros the log (trip distance): until LOG is displayed. 1 Press 2 Press + . 4-2 Reset total log Resetting zeros the total log (total distance), as well as the log and avg speed: until TOTAL LOG is displayed. 2 Hold + Reference Manual and Installation Manual 11 5 Depth, keel offset, too deep alarm, too shallow alarm Depth and keel offset The displayed depth is the distance from the transducer on the boat to the bottom of the water, plus or minus an offset which is called the keel offset: A positive keel offset displays depth as measured from a point above the transducer. For example, if you set the offset as the distance from the transducer to the surface, it will display the depth from the surface to the bottom of the water. Keel offset Water surface Depth of transducer Transducer Note: The boat illustrated uses a through hull transducer Keel offset Positive value Negative value A negative keel offset displays depth as measured from a point below the transducer. For example, if you set the negative offset as the distance from the transducer to the bottom of the keel, it will display the depth from the bottom of the keel to the bottom of the water. 5-1 Set depth units The units can be METERS, FEET or FATH: Press until DEPth is displayed, then hold until the units change; if necessary, hold until the units change again. 5-2 Set too deep alarm The too deep alarm sounds if the alarm is turned on and the depth becomes equal to or more than the too deep alarm depth. To set the too deep alarm: 1 Hold for two seconds to display the Too Deep Alarm screen: or . 2 To change the alarm depth, press 3 To turn the alarm on or off, press . 4 Press . Alarm is on Deep alarm value 12 Northstar NS3100 MULTI 5-3 Set too shallow alarm The too shallow alarm sounds if the alarm is turned on and the depth becomes equal to or less than the too shallow alarm depth. To set the too shallow alarm: 1 At the Too Deep Alarm screen, hold for two seconds to display the Too Shallow Alarm screen. Alarm is off Shallow alarm value 2 To change the alarm depth, press 3 To turn the alarm on or off, press 4 Press . or . . 5-4 Anchor watch To set an anchor watch, set the too shallow alarm to slightly less than the current depth and set the too deep alarm to slightly more than the current depth. Allow for tide changes. 5-5 Set keel offset Keel offset is described above. The range is ± 2. 9 m (± 9. 6 ft, ± 1. 6 fathoms): 1 Press + several times until the Keel Offset screen is displayed: or to change the keel offset. 2 Press 3 Press . Keel offset (negative) Reference Manual and Installation Manual 13 6 Temperature Temperature is measured by a sensor in the speed transducer. 6-1 Set temperature units The units can be either °C or °F: Press until the temperature is displayed, then hold until the units change. 6-2 Calibrate temperature The unit is factory calibrated and should not normally need calibrating. To calibrate: 1 Measure the water temperature near the speed transducer. 2 Press + several times until the Temperature Calibration screen is displayed. Water temperature 3 Press or to change the temperature to the value measured in step 1 above. 4 Press . 14 Northstar NS3100 MULTI 7 Countdown timer You can adjust the countdown timer to start counting down between one and ten minutes, in increments of one minute. When the timer is counting down, the countdown timer symbol flashes and the time remaining is displayed in minutes and seconds: The beeper sounds and any external beepers or lights operate: Four beeps at four minutes to go. Ten beeps at the end; the last beep is longer and marks the end of the countdown. In each case, the end of the last beep marks the exact minute. Timer counting down Countdown timer symbol flashes 7-1 Start countdown timer The timer starts at the start time (to adjust the start time, see section 7-3). The timer displays On briefly and starts counting down from the start time. 7-2 Stop and reset countdown timer 1 Press until the countdown timer is displayed. The timer stops and the time resets to the start time (see section 7-3). 7-3 Adjust start time 1 Press + several times until the Countdown Timer Start Time screen is displayed: 2 Press or to set the start time in minutes. The timer does not start now (to start the timer, see section 7-1). 7-3 Adjust start time Timer start time is 9 min Reference Manual and Installation Manual 15 8 Systems of several instruments Several Northstar instruments can be connected together during installation to share data. There are two ways of connecting instruments together, NavBus or NMEA. 8-1 NMEA NMEA is an industry standard. [. . . ] Trim speed displays ± . 00 to . 99, 1. 0 to 9. 9, 10 up Adjustable damping for speed and trim speed gives stable readings in all sea conditions; values of 1, 2, 3, 4 & 5 average readings over a time period of 6, 12, 18, 24 & 30 seconds respectively. Typical accuracy < 2% (depends on type of depth transducer, installation and water clarity). Adjustable keel offset ± 2. 9 m (± 9. 6 ft, ± 1. 6 fa) Too Deep and Too Shallow alarms (run both at once to provide anchor watch facility). Temperature Range 0 to 37. 7°C (32 to 99. 9°F); typical accuracy < 2°C. [. . . ]
