FAULT AND ERROR MESSAGES
NETWORK PILOT FAULT DISPLAY
If Network PILOT should have a fault the autopilot computer
unit will send a message to all other Network Display Units.
The Network DEPTH unit will alternately display the follow
message, the actual fault will have to read from the Network
PILOT Display unit.
UNIT INTERNAL ERRORS
In the unlikely event that your Network DEPTH unit should
develop an internal error, the unit will sound it's alarm
continuously and the display will show an error number.
Press any of the keys to reset the error condition and
silence this alarm. In some cases the fault can be cleared
by switching off the instruments at the supply, waiting a few
moments and then switching on again. If either of these
methods do not clear the fault the error number should be
recorded. Switch off the supply and disconnect the faulty
unit. Return it with the error number to your dealer for
servicing.
