Changing the code or master unit
You can change the code from any CodeLock compatible control unit
on your SeaTalk system, provided you know the current code.
Note: If you set up CodeLock in Auto mode, the unit on which you
enter the new code becomes the new master unit.
To change the code:
1. Display the CodeLock entry screen and enter your current code, as
shown in the flowchart.
The code is checked. If it is incorrect, the four dashes are
redisplayed and you must enter the code again. If it is correct, the
CodeLock status screen is displayed, with the status set to OFF.
2. Press
disp
to display the CodeLock entry screen again.
3. Enter the new code and move on to the CodeLock mode selection
screen.
4. Set the mode to Auto or Manual, as required.
5. Press and hold
standby
for 1 second to exit Intermediate Setup
and save the new settings.
4.3 Entering your code (Manual mode only)
If CodeLock has been set up in Manual mode, the correct code must be
entered on one of the control units every time the system is switched on.
The code number created on the master is entered via the keypad from
any CodeLock-compatible instrument, and this code is then sent to all
compatible instruments on the same SeaTalk bus. Once this code has
been received the instruments operate in the normal way.
