System menu 1 description

MENU: Selects system menu desired.

DEPTH UNIT: Selects unit of depth mea- surement among meters, feet, fathoms, or passi/braza. Default setting is feet.

SPEED UNIT: Selects unit of speed measure- ment among knots, miles per hour, or kilo- meters per hour. Default setting is knots. Requires speed data.

TEMP UNIT: Selects unit of temperature measurement; Celsius or Fahrenheit. Default setting is Fahrenheit. Requires temperature data.

ZOOM MARK: The zoom marker appears in the normal, bottom marker and bottom zoom displays and marks the area which is expanded in the bottom marker and bottom zoom pictures. You can turn on/off the marker as desired. The default setting is off.

F/A (Fish Alarm) LEVEL: Selects minimum echo strength level which triggers fish alarm; weak, medium, or strong. Default setting is medium.

TEMP GRAPH: Displays current water tem- perature in line graph form. (See illustration on page 2.) Default setting is off. Requires water temperature data.

LANG: Selects menu language; Japanese, English or etc. Default setting is English.

DISP SEL: Selects navigation displays: GRA1, steering display; GRA2, speed meter display; DATA, date display. Default setting is GRA1.

DRAFT: The zero line (sometimes referred to as the transmission line) represents the transducer’s position, and moves off the screen when a deep phased range is used.

TX OUTPUT: Selects transmitter output level; maximum or minimum.

NAV DSP: Selects nav data to display on the video sounder displays; position (L/L), range and bearing (R/B), or course (CSE). (For the location of the nav data indication, see the il- lustration on page 2.) Default setting is off. Requires nav data input.

NMEA: Selects NMEA data input format; Ver. 1.5 or Ver. 2.0. Default setting is Ver. 2.0.

BEARING: Ship’s course and bearing to a waypoint may be displayed in true or mag- netic bearing, on the graphic display. Mag- netic bearing is true bearing plus (or minus) earth’s magnetic deviation. Default setting is magnetic. Requires bearing data.

SPD SEL: Selects source of speed input; OFF, OWN (speed sensor), or NMEA (external). Default setting is OWN. Requires speed data.

TMP SEL: Selects source of water tempera- ture input; OFF, OWN (water temperature sensor), or NMEA (external). Default setting is OWN. Requires water temperature data.

SPD ADJ: If the speed sensor-generated speed indication is wrong, you can correct it here. (NMEA format speed data cannot be ad- justed.) For example, if the speed indication is 10% higher than actual speed, enter +10. Default setting is zero.

TEMP ADJ: If the water temperature sen- sor-generated water temperature indication is wrong, you can correct it here. (NMEA for- mat water temperature data cannot be ad- justed.) For example, if the water temperature indication is 2° higher than actual water tem- perature, enter -2. Default setting is zero.

BASIC RANGE 1–BASIC RANGE 8: Set range of each of the eight basic ranges. De- fault basic ranges are 15, 30, 60, 120, 200, 400, 1000, and 2500 (feet).
