Just some of the Vexilar firsts include: the first liquid crystal display, the first fish alarm, the first three color display, and the first CRT and straight line paper graphs, for the sport fisherman. 1 General Description The Edge 507 is like having two depth sounders in one. The features are designed to give the angler the best sonar for any situation. [. . . ] 2ND insures that the range will be adjusted so that the second echo of the bottom can appear on the screen. A-RNG-MODE does not insure that the second and third echoes will be visible, only that the range will be adjusted so that they can fit on the screen if the sonar sees them. The type of bottom and the Gain level will determine if the echoes appear. To change the A-RNG-MODE setting, press the Down arrow button to move down to the item. Then, press the Left or Right arrow buttons to change the setting. A-GAIN-LEVEL This item works with the Automatic Gain Control feature. The Automatic Gain Control, if selected, will adjust the level of gain according to the conditions. A-GAIN-LEVEL simply tells Auto Gain to keep the gain on the low side, in the middle, or on the high side of automatic gain level. To change the A-GAIN-LEVEL setting, press the Down arrow button to move down to the item. Then, press the Left or Right arrow buttons to change the setting. 16 A-MODE A-Mode gives an instantaneous, vertical, representation of the depth below. It gives you the ability to recognize bottom changes and targets before they scroll onto the normal display. Press the Left arrow to turn the feature OFF. USING THE FISH ALARM The Fish Alarm will sound a series of short beeps when the LC507 determines that there is a fish within the beam. Any target that is separated from the bottom signal could sound the Fish Alarm. If you find that the alarm is sounding more than it should, reduce the gain level. To activate the feature, press the Down arrow to move down to Fish Alarm item. Press the Right arrow to turn the feature ON and the Left arrow to turn it OFF. LEFT To select the frequency of the Left display, press the Down arrow to move to the item. A selection of N/A will cause the Right display to cover the full screen. Note - SWEEP, A-RNG-MODE, A-GAIN-MODE, and A-MODE work the same way for the Left beam as they do for the Right HARD-BTM-ALM The Hard Bottom Alarm will sound a series of long beeps when the third echo of the bottom is visible on the Left display. Important - If Auto Range is on, the A-RNG-MODE feature must be set to 2ND or 3RD for the Hard Bottom Alarm to work. 17 MENU 3 Menu page 3 controls features that affect all modes, no matter which one is currently selected. SUPER RANGE Super Range controls the way the display appears when the depth range changes. When Super Range is OFF, and the range changes, you will see the point at which the range changed on the display. This point will scroll across the screen until it disappears at the far left side. When Super Range is ON, there will be no visible point at which the depth changed. It is best to turn this feature ON, unless you have a specific reason to have it OFF. DEPTH The Depth feature controls how the digital depth number appears at the bottom of the display. [. . . ] There is a loss of clear water flow across the face of the transducer when the boat reaches a certain speed. SPEED-PULSE feature needs calibrating (contact customer service) Unit is turned on, but there is no display. Unit works well when sitting still or at slow trolling speeds, but loses reading when the boat speeds up. Unit works, but shows noise when the engine is started or the electric trolling motor is turned on. [. . . ]
