92 AQUAMAP™ 10x2/12x2 SERIESContour: Sets an alarm to sound when the transducer detects a suspendedtarget within the specified depth from the surface of the water and from thebottom.Fish: Sets an alarm to sound when the device detects a suspended target.• sets the alarm to sound when fish of all sizes are detected.• sets the alarm to sound only when medium or large fish aredetected.• sets the alarm to sound only when large fish are detected.Weather AlarmsBefore you can set weather alarms, you must have a compatible AQUAMAPconnected to a weather device, such as a GXM™ device, and have a validweather subscription.1 Select Settings > Alarms > Weather Alarms.2 Turn on alarms for specific weather events.Fuel AlarmBefore you can set a fuel level alarm, a compatible fuel flow sensor must beconnected to the AQUAMAP.You can set an alarm to sound when the total amount of remaining onboardfuel reaches the level you specify.1 Select Settings > Alarms > Fuel > Total Fuel Onboard > On.2 Enter the remaining amount of fuel that triggers the alarm, and selectDone.My Vessel SettingsNOTE: Some settings and options require additional charts or hardware.Select Settings > My Vessel.Depth and Anchoring: Allows you to enter information about the keel andthe anchor.Temp. Offset: Allows you to set an offset value to compensate for the watertemperature reading from a NMEA 0183 water-temperature sensor or atemperature-capable transducer.Calibrate Water Speed: Calibrates the speed-sensing transducer or sensor.Fuel Capacity: Sets the combined fuel capacity of all the fuel tanks on yourvessel.Vessel Type: Enables some AQUAMAP features based on the boat type.CZone™: Sets the digital switching circuits.System Profiles: Allows you to save your system profile to a memory cardand import system profile settings from a memory card. This can behelpful for charter or fleet vessels, and for sharing your setup informationwith a friend.Setting the Keel OffsetYou can enter a keel offset to compensate the water depth reading for thetransducer installation location. This allows you to view the depth of the waterbelow the keel or the true depth of the water, depending on your needs.If you want to know the water depth below the keel or the lowest point of yourboat and the transducer is installed at the water line or anywhere above theend of the keel, measure the distance from the transducer location to the keelof the boat.If you want to know the true water depth and the transducer is installed belowthe water line, measure the distance from the bottom of the transducer up tothe water line.NOTE: This option is only available when you have valid depth data.1 Measure the distance:• If the transducer is installed at the water line 1 or anywhere above theend of the keel, measure the distance from the transducer location tothe keel of the boat. Enter this value as a positive number.• If the transducer is installed at the bottom of the keel 2 and you want
