Some of their innovations include: · · · · · · The first straight-line paper graph The first CRT (television) display The first color display The first fish alarm The first Liquid Crystal Display (LCD) The first split-screen zoom flasher ABOUT FLASHERS How Sonar Works SONAR stands for SOund NAvigation Ranging. Sound travels through fresh water at a speed approximately 4920 feet per second. [. . . ] This feature is discussed more on page 24 FL-20 Activate the Auto Zoom by switching the Mode control to either the AZ 6' or AZ 12' setting to the right, or the AZ 6' or AZ 12' setting to the left. The right (Yellow) settings operate with the display at full brightness. The left (Red) settings operate the display in Night Mode, discussed on page 24. DID YOU KNOW ?Low Power Mode has little to do with how much battery power is required to run the flasher. Switching to Low Power Mode will not significantly increase your running time on a battery. You can have a Low Power Mode feature on an FL-8se too by purchasing a Vexilar S-Cable. 20 FL-20 Low Battery Indicator When battery power runs low, the red "Low Battery" indicator light will turn on. You can continue to use the flasher, but be aware your time is rapidly decreasing. When the indicator light begins to flash, failure due to low voltage is imminent. 21 Understanding Zoom When Zoom is active, the display is divided into two halves. If set to 60, triple the reading. FL-20 THE LEFT HALF represents the zoom view. THE RIGHT HALF represents the entire water column, from the water surface to the bottom. Read the depth using the inner red/white scale. FL-18 THE LEFT HALF represents the zoom view. THE RIGHT HALF represents the entire water column, from the water surface to the bottom. Read the depth using the inner yellow scale. Bottom The Zoom scale reads in the opposite direction as the full view scale. You can only see objects as far off the bottom as the zoom setting permits, which is 6 feet. Objects above this level will only appear on the right side which show the entire water column. Bottom The Zoom scale reads in the opposite direction as the full view scale. You can only see objects as far off the bottom as the zoom setting permits, either 6 feet or 12 feet. Objects above this level will only appear on the right side which show the entire water column. Fish Fish IMPORTANT Zoom should be activated only when the transducer is submerged. If the zoom is activated before the transducer is placed in the water, the bottom may not line up with the zero mark on the zoom scale correctly. If this happens, simply switch the flasher to Normal Mode, or Full View Mode, and then back to Zoom to reset the feature. 22 23 Bottom Lock ( FL-18 Only ) The FL-18 also has a zoom feature called Bottom Lock (BL). This works the same as Auto Zoom, except the flasher continuously updates the position of the bottom in the magnified view. [. . . ] For fiberglass hulls, the engine's out-drive should act as this connection in addition to a bow mounted trolling motor's motor shell. EQUIPMENT Electric trolling motors and main engines can have technical problem that cause interference. If common wiring improvements do not solve the problem, be sure to check with the manufacturer to see if there are any recommendations or updates available regarding interference with depth sounders. For more information regarding interference issues, check the Help Department of the Vexilar web site or contact our service department. POSSIBLE CAUSE Check for bad connections, proper hook up polarity, and make sure you have a good, fully charged, battery. [. . . ]
