The display normally shows depth. If it displays dashes (— —) then it means that the depth is too deep or unknown.

2-3 Alarms

The Explorer D310 can be set to sound an alarm when the water is too deep or too shallow (see sections 3-2 and 3-3). When the alarm sounds, the internal beeper sounds, the symbol on the display flashes and any external beepers or lights operate.

Press to mute the alarm. The alarm stays muted until the depth becomes normal. The alarm will sound if the depth becomes too deep or too shallow again.

2-4 Simulate mode

Simulate mode allows you to become familiar with the unit off the water. In Simulate mode, the Explorer D310 functions normally except the transducer is ignored and the unit generates this data internally. The word SIMULATE flashes at the top, left corner of the screen.

To turn Simulate mode on or off:

1Turn the power off.

2Hold down while you turn the power on.
