The SPX-5 Tiller system supports the alarms listed on the following pages. When an
alarm occurs, a beep sounds and the appropriate alarm message is displayed.

Unless otherwise stated, if an alarm occurs, press standby to clear the alarm and
•
return to hand steering.
• If more than one alarm occurs, as each alarm is cleared, the next is displayed.

LARGE XTE
MOB
NEXT WPT?
Description and possible actions
Large cross track error
Occurs if the cross track error exceeds 0.3 nm. The alarm clears if the
heading recovers.
Man OverBoard alarm
The SPX-5 Tiller system activates the Man Overboard alarm if it
receives a man overboard (MOB) message from another instrument
on the SeaTalk system. It displays the text MOB instead of the way-
point number on the XTE, DTW and BTW data pages.
If the autopilot is in Track mode, it will sound the Waypoint Advance
alarm to notify you of the change in waypoint.
Waypoint advance alarm
The SPX-5 Tiller system activates the Waypoint Advance alarm
whenever the target waypoint changes. This occurs when:
you select automatic acquisition by pressing track from Auto
•
you request waypoint advance by pressing track for 1 second in
•
Track mode (with SeaTalk navigators only)
• the boat arrives at the target waypoint and the navigator accepts
the next waypoint
• you activate the Man Overboard (MOB) function in Track mode
When the alarm sounds, the pilot continues on its current heading but
displays:
• the bearing to the next waypoint
• the direction the boat will turn to take up that bearing
Responding to a Waypoint Advance alarm
To respond to a Waypoint Advance alarm:
check that it is safe to turn onto the new track, then press track to
•
accept the waypoint advance
• alternatively, you can cancel the alarm without accepting the
waypoint advance by pressing: standby to return to hand
steering, or auto to return to Auto mode.
• Note: Waypoint advance only operates if the SPX-5 Tiller system
is receiving valid bearing to waypoint and waypoint number
information.
