18 echo 200, echo 300c, echo 500c, and echo 550c Owner’s ManualAppendixappendixSpecificationsSpecification MeasurementTemperature Range echo 200: From 5°F to 158°F (from -15°Cto 70°C)echo 300c/500c/550c: From 5°F to 131°F(from -15°C to 55°C)Compass Safe Distance echo 200: 9.9 in. (250 mm)echo 300c: 13.8 in. (350 mm)echo 500c/550c: 15.75 in. (400 mm)Power Source Voltage Range 10–28 VdcRated Current 1 AFuse AGC/3AG - 3.0 AFreshwater Depth* echo 200/300c: 1500 ft. (457 m)echo 500c/550c: 1900 ft. (579 m)Saltwater Depth* echo 200/300c: 600 ft. (183 m)echo 500c/550c: 700 ft. (213 m)* Depth capacity is dependent on water salinity, bottom type, and other water conditions.The transducer provided with the echo 200/300c/500/550c has beam anglesof 15 and 45 degrees at 3dB. However, when this transducer is used withthe echo device, it can detect the smallest signals up to 60 and 120 degrees.Shallow and deep water performance is maximized because the echo seriesshows more fish when shallow, and reaches deep to show structure andbottom contours.Cleaning the Outer CasingNoticeAvoid chemical cleaners and solvents that can damage plastic components.1. Clean the outer casing (not the screen) of the device using a clothdampened with a mild detergent solution.2. Wipe the device dry.Cleaning the ScreenNoticeCleaners containing ammonia will harm the anti-reflective coating.The device is coated with a special anti-reflective coating which is verysensitive to skin oils, waxes, and abrasive cleaners.1. Apply an eyeglass lens cleaner specified as safe for anti-reflectivecoatings to the cloth.2. Gently wipe the screen with a soft, clean, lint-free cloth.System SettingsSetting the Language1.
