Set up Sonar
Adjust the CHIRP Frequency Spectrum (optional, CHIRP models only)
Your control head has been configured with the best settings for a wide range of fishing conditions, and we recommend using the
entire CHIRP frequency spectrum included with your unit. However, you can adjust the CHIRP Frequency Spectrum to limit the
i
nterferences on the display or refine the settings to your preference. The menu options are determined by the installed transducer
a
nd control head model.
Requirements: CHIRP mode must be turned on. The menus are also determined by the display frequency you have selected for
each view.
WARNING! If an accessory transducer is installed, confirm it is configured in the control head. See Set up an Accessory
Transducer for details. For information about accessory transducers, visit our Web site at humminbird.com.
