Onwa Marine Electronics KAP-833 - Manual (Page 12)

A number of conditions will cause alarms to sound. In some cases, lights on the
control panel will also blink. Each alarm has a different
beep pattern (except
stopwatch and commercial watch alarm). The external alarm output may also be
turned on by some of these alarms; this does not have a
beep pattern .
Stopwatch Timer Alarm
This alarm indicates that the time set by the user has expired.
Alarm pattern is 0.2 second on, 0.2 second off until reset.
The external alarm output is turned on 1 minute after the internal alarm
commences. Note that a suitable piezo buzzer must be attached to this
output. This is not supplied with the KAP-833 but is available as an option.
Angle Off Course Alarm
The alarm pattern is 0.2 seconds on, 0.2 seconds off when vessel is more
than the set number of degrees from course-to-steer. The
off-course
light blinks on and off at the same rate as the audible alarm. The angle at
which this alarm sounds can be set to any desired limit (including
completely disabled).

An alarm will sound if the vessel has deviated from its desired course by more
than a set number of degrees. This can be caused by a number of steering faults,
any of which require attention by the crew.
The angle at which this alarm sounds may be set to any value between 1 and 180
degrees.
To set the off-course alarm angle
Enter the desired angle in degrees from the keypad, and then press the
off-course button.

To examine the current off-course alarm angle
When no digits entered from the keypad, press the off-course button. The
currently set alarm angle (in degrees) will be displayed for two seconds.
When the allowable angle is exceeded, the off-course alarm will sound and the
off-course light will flash. When the vessel is brought on to its correct course
again, the alarm will cease.
Changing to power-steer or standby modes will cancel the alarm.
The default value for the off-course angle (ie the one set when the KAP-833 is
turned on) is 30 degrees.
Note that the alarm will sound if a large course change is entered (eg from
keypad, preset course or course change knob). This alarm will cease as soon as
the vessel completes its course change. The alarm may also sound when changing
from one section of a GPS route to another, and will cancel itself when the
course change is completed.
