USING THE LCR400ID
OPERATING THE LCR400ID
SENSITIVITY
1. Selecting Sensitivity/Units;
Factory setting: +0/FEET
The Sensitivity/Units function has two uses: It lets you
adjust LCR 400ID sensitivity and controls whether depth
measurement is in feet or fathoms.
The LCR 400ID automatically increases or decreases its
sensitivity setting when water conditions change (as
when the bottom is stirred up). If you want to manually
adjust Sensitivity, select SENS and press the Up or Down
arrow button to adjust the automatic setting with a “+5” to
“-5” range. For example, if you set it at “+2”, Sensitivity
remains 2 settings higher than the normal automatic
setting.
Pressing the ON-OFF button when the SENS menu is
displayed switches the unit of depth measurement
between feet and fathoms.
BOTTOM ALARM
2. Enabling Bottom Alarm;
Factory Setting: OFF
The Bottom Alarm lets you specify the minimum depth
you want to maintain. To use it, select B ALM; then
press the ON-OFF button to activate the alarm, and the
Up or Down arrow key to adjust the depth at which the
alarm will sound. An alarm symbol is displayed when
this function is on.
When Bottom Alarm is on, you’ll hear a continuous
chirping sound when the bottom is shallower than you
defined. This is very handy for alerting you to shallow
water or helping you to maintain position over structure.
