Key Lock Function; Locking All The Keys - A&D BM series Instruction Manual

17. Key Lock Function

Sending specified commands to the balance will lock the keys on the balance to disable the key
functions. This is useful for controlling the balance only by an external device such as a personal
computer.
Even if the keys are locked, key operations using commands are available. For details on
commands to operate the keys, refer to "16.3. Commands".
The key lock state can be checked using the command to request the state of the balance keys.
The key lock state is maintained until the balance receives the key unlocking command or the
balance is turned off by removing the AC adapter.
The key lock function (KL command and LK command) is available for balances with software version
1.660 or later.
