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. [. . . ] The right selection operates Auto Zoom at the normal power level. The left selection operates Auto Zoom in Low Power Mode. FL-12 and FL-20 Activate the Low Power Mode by switching the range control from OFF to the left. You can use any of the Mode settings in Low Power Mode. Bottom Lock (BL) The FL-18 also has a zoom feature called Bottom Lock (BL). 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. When reading depths always use the inner scale on the right side. When the range is set to 20, read this scale "as is". When the range is set to 40, double the reading. If set to 60, triple the reading. FL-20 THE LEFT HALF represents the zoom view. Read the distance from the bottom using the large white scale. 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. [. . . ] Also, gain may be set too high or , if gain is set to minimum, switch to the LP Mode. Improper transducer type, installation, or adjustment causing a loss of clear water flow across the transducer when the boat reaches a certain speed. Also can be improper grounding or missing ground in electrical system. I. R. Can't eliminate interference Gain may be set too high or the other unit from other depth finder. [. . . ]
