Zoom
Another form of range control is Zoom. Zoom allows selection of various ranges for full
screen viewing. By using the display to view a smaller area, the effective display resolution is
increased, and the units ability to separate targets close together is enhanced.
The zoom range is determined by the depth range in use when Zoom is enabled. In
shallow water, when the 15' or 30' depth range is used, the zoom range will be 7 1/2'. If the 60' or
120' depth range is in use, the zoom range will be 15', if a 180' - 480' depth range is used, the
zoom range will be 30', and if the 600' range is in use, the zoom range will be 60'.
Pressing the UP or DOWN arrow button enables zoom and adjusts the zoom 'window' to
the desired depth. The upper and lower limits are shown on-screen and the and the digital depth
readout will continue to track the bottom even when Zoom is enabled.
To disable Zoom press the UP arrow button until Zoom turns off.
Bottom Alarm
The LCR W contains an audible
alarm to warn you of shallow water
depths. This alarm is adjustable from 2' to
99' of depth. To enable the alarm, simply
adjust the alarm depth using the UP and
DOWN arrow buttons. When the depth of
the water beneath your boat is equal to or
less than the selected alarm depth, a
continuous alarm will sound.
To disable the alarm, either move
to deeper water, or use the UP button to
turn the alarm off.
