[. . . ] In the event that a particular button has no function or is inappropriate for the situation, an audible "error", or multiple chirps, will be heard. POWER, powers the Wide Optic up for normal operation. When the unit is on, POWER turns the unit off. POWER can also be used to go directly into Simulator mode. With the unit powered off, press and hold POWER for several seconds until a continuous chirp is heard. LIGHT controls the unit's 3-position display backlight. With the unit powered on, pressing LIGHT once will turn the backlight on "high". Pressing LIGHT a second time will turn the backlight on "low", and pressing a third time will turn the backlight off. The backlight is very effective for low-light and nighttime operation. When the backlight is on, the Wide Optic will consume more power than with the backlight off. This is important when using the Wide Optic in a portable configuration powered by a separate battery, or when powering the unit from a trolling motor battery. NOTE: When powering the unit from a battery such as in portable applications, avoiding use of the backlight prolongs battery life. The three lower buttons, MENU, UP ARROW, and DOWN ARROW work together to control the Wide Optic menu-controlled user functions. MENU brings a menu on-screen for adjustment. In normal operation, pressing MENU repeatedly will cycle through all available menu headings. When the desired menu heading is displayed, the full menu appears after a short pause. A menu remains onscreen for several seconds allowing user adjustment by means of the ARROW keys. If no adjustment is made in the allotted time, the menu disappears. If you need the menu to remain on-screen longer to study the adjustment options, press and hold MENU-the menu will remain on-screen indefinitely. Once you release the menu button, the screen will time out. Once a menu times out, it is still considered the active menu. Pressing MENU will bring up the last used menu. The UP ARROW and DOWN ARROW make adjustments to menu functions. On the left side of every menu there are UP ARROW and DOWN ARROW symbols. [. . . ] The Wide Side transducer uses 3 different sonar elements which transmit signals to the left, right, and straight down from your boat. The downward beam is 200 kHz with a 24 degree area of coverage. This beam maintains a continuous digital depth readout from the bottom directly beneath your boat. The side beams are 455 kHz with a 16 degree area of coverage. [. . . ]
