Thank you for choosing Humminbird®, America's #1 name in fishfinders. Humminbird® has built its reputation by designing and manufacturing top-quality, thoroughly reliable marine equipment. Your Humminbird® is designed for trouble-free use in even the harshest marine environment. In the unlikely event that your Humminbird® does require repairs, we offer an exclusive Service Policy - free of charge during the first year after purchase, and available at a reasonable rate after the one-year period. [. . . ] WhiteLine® highlights the strongest sonar returns in white resulting in a distinctive outline. (See Bottom Presentation for more information. ). To adjust the Bottom View: 1. Use the LEFT or RIGHT 4-Way Cursor Control keys to change the Bottom View setting. (Structure ID, WhiteLine, Default = Structure ID) Zoom Width Zoom Width adjusts the width of the Zoom window on the Sonar Zoom View. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Zoom Width setting. (Narrow, Medium, Wide, Default = Wide) Real Time Sonar (RTS®) Window RTS® Window sets the RTS® Window to either Wide or Narrow, or turns it off in the Sonar View. The RTS® Window always updates at the fastest rate possible and only displays returns that are within the transducer beam. (See Real Time Sonar (RTS®) Window for additional detail). RTS® Window (Wide) RTS® Window (Narrow) RTS® Window (Off) To change the RTS® Window setting: 1. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the RTS® Window setting.

Increasing the 83 kHz Sensitivity will display additional weak returns and decreasing the 83 kHz Sensitivity will display fewer weak returns. The 83 kHz Sensitivity menu choice is only available when User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: 83 kHz Sensitivity is particularly useful for adjusting the sensitivity of the 83 kHz sonar returns in the 200/83kHz Split Sonar View. The 83kHz sensitivity can be adjusted without affecting the sensitivity of the 200 kHz returns shown in the 200 kHz sonar window. 455 kHz Balance adjusts the sensitivity of the 455 kHz beam. Increasing the sensitivity will display additional weak returns and decreasing the sensitivity will display fewer weak returns. A QuadraBeamTM transducer must be attached to the 700 SeriesTM Fishing System. The 455 kHz Balance menu choice is available when Transducer Select is set to QuadraBeamTM (see Sonar Menu Tab: Transducer Select) and User Mode is set to Advanced (see Setup Menu Tab: User Mode). NOTE: The 455kHz Balance requires the purchase of the QuadraBeamTM transducer. You can visit our website at www. humminbird. com to order this accessory online or contact our Customer Resource Center at 1-800-633-1468. NOTE: 455 kHz Balance is particularly useful for adjusting the sensitivity of the 455 kHz sonar returns in the Side Beam View. The 455 kHz sensitivity can be adjusted without affecting the sensitivity of the 200 kHz returns shown in the 200 kHz sonar window. To set the 83 kHz Sensitivity: 1. Make sure you are in Advanced User Mode, then highlight 83 kHz Sensitivity on the Sonar main menu. Use the LEFT or RIGHT 4-WAY Cursor Control keys to set the 83 kHz Sensitivity. (-10 to +10, Default = 0) To change the 455 kHz Balance setting: 1. Make sure you have selected QuadraBeamTM Transducer and Advanced Mode and that the QuadraBeamTM transducer is connected, then highlight 455kHz Balance on the Sonar Main Menu. [. . . ] Additionally, the transmitter has the capability to create very precise sonar pulses needed for a high degree of target separation. Humminbird® receivers are extremely sensitive, but within a narrow "bandwidth" to discriminate against noise from external sources. Additionally, the receiver offers a wide "dynamic range" which provides the ability to receive very strong signals alternating with very weak signals, without the strong signal overwhelming the weak signal. TripLog: TripLog is a Humminbird® feature that provides an on-screen counter for Elapsed Time, Average Speed and Total Distance traveled, and requires a speed input to activate the feature. [. . . ]
