Chapter 4: CodeLock
CodeLock is a personal four-digit security feature designed to protect
your valuable instruments against theft. You donít have to activate the
system, but itís there if you need to. You can activate it using any
CodeLock-compatible control unit on your SeaTalk system.
When you first enter a code and activate CodeLock, the code is sent to
all the CodeLock-compatible units on the system. After this, whenever
you power on the system, the units will only start up if they receive the
correct code.
Remember to fix a CodeLock sticker by each instrument, to deter
potential thieves.
4.1 CodeLock modes
When you set up CodeLock, you can choose whether the code will be
sent automatically or must be entered manually at power on, as follows:
ï Auto mode is used when there is a display unit situated in a secure
location, ideally below deck, or one which can be unplugged and
removed to a secure location. You enter your chosen code on this
ìmasterî unit when you first activate CodeLock. This code is then
automatically sent to all CodeLock-compatible display heads on
SeaTalk, without further intervention, every time the system is
powered on.
ï Manual mode is used to provide a higher degree of security,
perhaps when all your instruments are mounted in exposed
locations. In this case, you must enter your personal code every time
the system is switched on. The code can be entered into any
convenient CodeLock-compatible control unit, and is then sent to all
the other compatible units via SeaTalk.
4.2 Setting up CodeLock
CodeLock is set up and activated on the ST4000 Plus using the
Intermediate Setup options.
Initial setup
When you first install your ST4000 Plus, CodeLock is set OFF. To
