Screen Snapshot: When Screen Snapshot is enabled (from the Accessories menu tab), pressing the MARK key creates a saved screen capture (when you have an optional-purchase MMC/SD card installed). Once you have created a screen capture, a screen capture thumbnail is added to the Snapshot and Recording View, and is available to view at a later date. See the full-sized image by highlighting a thumbnail (using the Up or Down 4- Way Cursor keys), then using the Right 4-Way Cursor key to view the full image. A border around the full-size screen snapshot indicates that it is just a screen snapshot, not a “live” view. You can delete the selected image, or all images, by selecting a thumbnail and using Delete Image, or using Delete All Images from the Snapshot and Recording X-Press™ menu.

Working with screen snapshots is a four-step process:

1.Enabling Screen Snapshot from the Accessories Menu.

2.Making a Screen Snapshot using the MARK key.

3.Viewing a Screen Snapshot using the Snapshot and Recording View.

4.Deleting a Screen Snapshot using the Snapshot and Recording X-Press™ menu.

For more information, see Accessories Menu Tab: Using Screen Snapshot and Snapshot and Recording X-Press™ Menu.

When you start a screen snapshot, you will see a message that a waypoint has been created at the point where your cursor is on the screen, and the screen will freeze while the snapshot is being saved to the MMC/SD card. A status dialog box will appear that shows the progress of the save as a percentage, and that displays the numbered file name assigned to the .BMP file that is being created. Snapshot filenames begin with the letter "S". For more information, see Accessories Menu Tab: Using Screen Snapshot procedure and Snapshot and Recording X-Press™ Menu.

Recording and Playback: From the Snapshot and Recording View, you can use the X-Press™ menu to start and stop recording, and to change the pings per second (which alters the detail level of the recording). Once you are recording already, playing back a recording and screen snapshot viewing are not allowed, and the only Sonar Recording menu choices available in the X-Press™ menu are Stop Recording and Pings Per Second. Use the 4-WAY Cursor keys from the Snapshot and Recording View to start playback of a specific recording icon. You can then cycle through all the views using the VIEW key to see what those views looked like during the recorded time period. You can also use the X-Press™ menu to change playback speed, stop playback, and delete recording icons.

Working with sonar recordings is a six-step process:

1.Displaying the Snapshot and Recording View.

2.Starting a sonar recording using the Snapshot and Recording X-Press™ menu.

3.Changing the maximum ping rate for the recording using the Snapshot and Recording X-Press™ menu (optional).
