Alarms menu
The table below show the alarms available and related settings.
Deep Water If this option is set to On, an alarm is triggered when the
depth exceeds the value that you specify. This option is only
available when the sonar is enabled.
Note: The Deep limit cannot be set to a value less than
the Shallow Limit.
Shallow Water If this option is set to On, an alarm is triggered when the depth
drops below the value that you specify. This option is only
available when the sonar is enabled.
Note: The Shallow limit cannot be set to a value greater
than the Deep Limit.
Fish If the Fish alarm and fish depth limits alarm are set to On, a
warning sound is triggered if any target meets the sensitivity
level and is within the Shallow Fish Limit and Deep Fish Limit
that you specify. The following items are available in the
sub-menu:
• Fish — Switches fish alarm On and Off.
• Fish Sensitivity — If the Fish alarm is set to On, an alarm
is triggered when the fish return strength reaches the
sensitivity that you specify.
• Fish Depth Limits — Switches depth limits On and Off.
• Shallow Fish Limit — Specifies the lower value for the
Fish Alarm Depth Limit.
• Deep Fish Limit — Specifies the upper value for the Fish
Alarm Depth Limit.
Water Temperature When set to On, an alarm and pop-up message is triggered
when the water temperature is equal to or lower than the Lower
Temp Limit, or equal to or greater than the Upper Temp Limit.
Waypoint Arrival When you arrive at a waypoint, an alarm is triggered. This
setting allows you to specify the distance from the target
waypoint at which the alarm is triggered.
