Your Fishfinder will start up with the backlight on and will automatically turn it off to conserve power. To turn the backlight on for night fishing, or to adjust the display contrast, press the POWER/LIGHT key to access the Light and Contrast menu. Use the 4-WAY Cursor key to

select Light or Contrast and then use the LEFT or RIGHT Cursor key to change the settings. Press EXIT to exit the Light and Contrast menu.

Press and hold the POWER/LIGHT key for 3 seconds to turn the unit off. A message will appear telling you how many seconds there are until shutdown occurs. Your Fishfinder should always be turned off using the POWER/LIGHT key. This will ensure that shutdown occurs properly and any menu settings will be saved.

The VIEW key is used to cycle through all available views. Press the VIEW key to advance to the next view. Repeatedly pressing VIEW cycles through all views available. Views can be hidden to optimize the system to your fishing requirements (see Views Menu Tab).
