2.20 Lock function
The "LOCK" function is a safety feature included in the AP20
system when you have more than one control unit installed. It
will disable all control units except for a single, user selected
control unit location.
When the "lock" function is in use, no transfer of command may
take place; only the "active" control unit stays in command.
To enable the "lock" function, make a quick double press on the
