is set to Advanced (see Setup Menu Tab: User Mode).
To change the Depth Lines setting:
1. Make sure you are in Advanced User Mode, then highlight Depth Lines on the
Sonar main menu.
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to turn the Depth Lines setting
On or Off. (Off, On, Default = On)
