Delete Recording (Optional-Purchase Sd Memory Card, Snapshot And Recording View Only); Delete All Recordings (Optional-Purchase Sd Memory Card, Snapshot And Recording View Only); Pings Per Second (Optional-Purchase Sd Memory Card, Snapshot And Recording View Only) - Humminbird 688ci HD DI Operation Manual

Delete Recording allows you to delete a single sonar recording. This menu
option is only available when an optional-purchase SD memory card is
installed, Snapshot and Recording View is on the screen, and you have selected
a recording file.
Delete All Recordings allows you to delete all the recordings at once. This
menu option is only available when an optional-purchase SD memory card is
installed and Snapshot and Recording View is on the screen.
Pings Per Second allows you to specify the ping rate for an active sonar
recording.
NOTE: Pings Per Second is available when an optional-purchase SD memory card
is installed, Snapshot and Recording View is on the screen, and the control head
is actively recording (not playing back).
Auto is the default setting for Pings Per Second and automatically adjusts the
ping rate for best recording quality. If there is limited memory on your SD
memory card, you can slow the ping rate by setting the Pings Per Second
manually, but the recording will capture less sonar detail. For maximum
performance, keep the Pings Per Second setting on Auto.
