Humminbird LCR 400 ID manual Sensitivity, Bottom Alarm

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.
