0 to 240 Ft., 0 to 480 Ft., 0 to 960 Ft., and 0 to 1500 Ft. You may manually change the depth range by pressing the depth set button and then either the increase or decrease button. Each time one of the set buttons is depressed the range will change by one setting.

Note: Should you attempt to change to a depth range which is less than the actual bottom depth, the computer will automatically change the depth range back to the proper position. For example, if you are in 40 feet of water and you change the depth range to 30 feet, the computer will automatically change back to the 60 foot range.

Manual Mode: - In the Manual Mode (See Paragraph 7 below) the automatic range change is not active. This means that you must manually set the depth range. For example, if you are on the 0 to 30 foot range and the bottom goes from 25 feet to 35 feet, you press the depth set button and then the (increase) button to change to the 0 to 60 foot range.

The depth range can also be changed by only pressing the depth set button. Each time this button is pressed the depth range will decrease (become shallower).

Remember that because of the LCR's Total Screen Update feature, information is automatically being put into memory in smaller increments (pieces) than is being displayed on the normal depth scales (see explanation of Total Screen Update earlier in manual). This means, for example, that even though you are on the 0 to 240 ft. scale, when you change to the 0 to 30 ft. scale the information will be displayed just as if you had been on the 0 to 30 ft. scale all along. No information or resolution is lost.

5.Display Stop/Resume: Anytime during the operation of the LCR you may stop the display by simply pushing the Display Stop/Resume button. This button has been highlighted with a yellow circle to make it easy to find. This feature will aid in the learning and interpretation of the display by giving you time for study. When the display is stopped the display speed and sensitivity setting cannot be changed.
