The features are designed to give the angler the best sonar for any situation. [. . . ] 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. It shows as a narrow band just to the right of the scrolling display. To activate the A-MODE, press the down arrow to move to the item. Press the Right arrow button to turn the feature ON. 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. Obviously, not all of these targets will be fish. The level at which the alarm sounds is controlled by the Gain. 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. Then, press the Left or Right arrow buttons to change the selection. 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.
