AUTOHELM ST 50 plus - Page 36

Mode 3 :
'CODE Lock' input
at Power-On (page
30)
In the
'Power-0n mode', the
ST50 Plus is configured
so that you
have to
enter the
four digit number on
a 'master' digital
instrument every time
the
system
is switched on . Until this
number is entered
the
instrument(s)
will not
operate .
This
mode is particularly useful
when you are unable
to position a 'master'
instrument
below decks and,
therefore, all the vessels
valuable instrumen-
tation is
left
in
a vulnerable area .
Should a
CODE Locked instrument
be removed from
the system, it will
not
operate until
the correct four digit
security number is entered
or received .
If your
selected master instrument
fails for any reason,
the security code
number can be
entered via another
ST50 Plus instrument in
the system .
However, until
another instrument is set
as a master or the
existing master
is replaced, the security
code will have
to be entered every time
the
system is switched on .
Note :
A warning
sticker is provided
with each instrument
. If you have set
'CODE
Lock',
position this warning sticker
in a prominent
location to deter
potential thieves
.

ST50 Plus GPS/Navdata
is switched on for
