ST50 Plus Depth Operation and Installation Handbook
In the ‘Power& mode’, the ST50 Plus is configured so that you have to
enter the four digit number on the master 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 instrlt
mentation 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.
Setting Up the Security Code
When the ST50 Plus Depth is switched-on for the first time the security
feature is set to off. To turn the ‘CODE Lock’ feature on, proceed as
follows:
