Delete All Recordings
(optional-purchase MMC/SD Card,
Snapshot and Recording View only)
Delete All Recordings allows you to delete all the recordings at once from
the Snapshot and Recording View. This menu option is only available when
you have an optional-purchase MMC/SD card installed and you are in
Snapshot and Recording view.
To delete all recordings:
1. From the Snapshot and Recording View, highlight Delete All
Recordings on the Snapshot and Recording X-Press™ Menu.
2. A confirmation dialog box will ask if you want to delete all
recordings. Select Yes to delete, or No to change your mind.
Pings Per Second
(optional-purchase MMC/SD Card,
Snapshot and Recording View only)
Pings Per Second allows you to specify the maximum ping rate for the sonar
recording currently in progress from the Snapshot and Recording View. This
menu option is only available when you have an optional-purchase MMC/SD
card installed and you are in Snapshot and Recording View and are actively
recording (not playing back).
To specify the pings per second:
1. Highlight Pings Per Second on the Snapshot and Recording X-Press™
menu, and press the RIGHT 4-Way Cursor key to increase and decrease
the number in the menu bar. (1-AUTO, Default = AUTO)
Playback Speed
(optional-purchase MMC/SD Card,
Snapshot and Recording View only)
Playback Speed allows you to specify the playback speed for a sonar
recording from the Snapshot and Recording View. This menu option is only
available when you have an optional-purchase MMC/SD card installed and
you are playing back a recording.
To specify playback speed:
1. Highlight Playback Speed on the Snapshot and Recording X-Press™
menu, and press the LEFT or RIGHT 4-Way Cursor key to display the
following Playback Speed submenu choices (which are represented
by icons): Beginning, Rewind2, Rewind, Reverse Normal, Reverse
Slow, Pause, Slow Play, Normal Play, FF, FF2, End.
NOTE: You can also change playback speed in the Snapshot and Recording View
using the Left and Right 4-Way Cursor keys, although you cannot skip to the
beginning or end of a recording using these keys.
NOTE: Sonar chart speed is increased during Fast Forward and reversed during
Rewind. This may result in a reduced quality sonar image, since at higher speeds,
not every sonar return can be processed.
