Alarms Tab

Contains settings for the unit’s alarms. (For a list of alarms and unit messages, see page 28.) The Alarms Tab is divided into two submenu tabs: Sonar alarms and System alarms.

Sonar alarms:

•Fish — sets alarm/icon to sound/display when unit detects a ﬁsh of the speciﬁed symbol size.

•Shallow Water/Deep Water — set alarms to sound when you enter an area of speciﬁed depth that is too shallow and/or too deep.

•Drift — sets an alarm to sound when you’ve exceeded a speciﬁed drift depth range. For example, if the value is set to 5 ft. and the current depth is 20 ft., the alarm will sound if the unit detects a depth greater than 25 ft. or shallower than 15 ft.

•Water Temperature — sets an alarm to sound when the transducer reports a temperature either above, below, inside or outside the speciﬁed values.

System alarms:

•Battery — sets an alarm to sound when the battery is reaching a critical state of discharge.

•Timer — allows you to choose between a Count Dn (Down) or Count Up timer. You may specify a duration for the Count Dn (Down), Stop, or Reset the timer.
