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 change the 455 kHz Balance setting:
1. Make sure you have selected QuadraBeam TM Transducer and Advanced Mode, then
highlight 455kHz Balance on the Sonar Main Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the 455 kHz Balance.

WideSide® Sensitivity
(Advanced: with WideSide® transducer)
WideSide® Sensitivity adjusts the sensitivity of the WideSide® beam. Increasing the sensitivity will
display additional weak returns and decreasing the sensitivity will display few weak returns. A
WideSide® transducer must be attached to the 700 Series™ Fishing System. The WideSide®
Sensitivity menu choice is available when Transducer Select is set to WideSide® (see Sonar Menu
Tab: Transducer Select) and User Mode is set to Advanced (see Setup Menu Tab: User Mode).
NOTE: The WideSide® Sensitivity requires the purchase of the WideSide® 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: WideSide® Sensitivity is particularly useful for adjusting the sensitivity of the 455 kHz sonar
returns in the WideSide® View. The 455 kHz sensitivity can be adjusted without affecting the
sensitivity of the other sonar frequencies.
To change the WideSide® Sensitivity setting:
1. Make sure you have selected WideSide® Transducer and Advanced Mode and that the
WideSide® transducer is connected, then highlight WideSide® Sensitivity on the Sonar
Main Menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the WideSide® Sensitivity.
