Depth Alarms

ALARMS

The X-65 has three different types of sonar alarms. The first is the Fish Alarm. It sounds when the Fish I.D. feature determines an echo or group of echoes is a fish. Another alarm is the Zone Alarm which consists of a bar. Any echo that appears inside this bar triggers this alarm. The last alarm is called the Depth Alarm. Only the bottom signal will trigger this alarm. This is useful as an anchor watch, a shallow water alert, or for navigation.

To adjust an alarm, first press the ALARM key. The screen shown at right appears. Follow the instructions below for setting each alarm.

The depth alarms sound a tone when the bottom signal goes shallower than the shallow alarm’s setting or deeper than the deep alarm’s setting. For example, if you set the shallow alarm to ten feet, the alarm will sound a tone if the bottom signal is less than ten

feet. It will continue to sound until the bottom goes deeper than 10 feet. The deep alarm works just the opposite. It sounds a warning tone if the bottom depth goes deeper than the alarm's setting. Both depth alarms work only off the digital bottom depth signals. No other targets will trip these alarms. If you turn the digital off, the depth alarms will be inoperative. These alarms can be used at the same time or individually.

To adjust the shallow alarm, highlight the "Shallow Depth" label. To adjust the deep alarm, highlight the "Deep Depth" label. Both alarms adjust iden- tically. We'll use the shallow alarm as an example. Highlight the "Shallow Depth" label, then press the right ar- row key. The screen shown at right appears.

Use the up or down arrow keys to select the number, the right and left keys to move from number to number

in the depth. For example, to set the shallow alarm depth to 10 feet, press the right arrow key once, then press the up arrow key once. The changes
