Mode 3: ‘CODE Lock’ input at Power-On (page 24)
In the ‘Power-On 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.

Power
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.
lf
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 securii code will have to be entered every time the
system is switched on.
Note; A warning sticker is provided with each instrument.
lf
you have set

potential thieves.
