Delete all Master Cards
For this process, it is not necessary
to use the Master Cards.
To remove all the Master Cards at
once, place the Management Card
close to the lock 4 times (4 beeps).
■ To finish the process correctly,
wait 5 seconds until the intermittent
beeps stop. A final confirmation
sound will indicate the end of
the process.
Wrong process : 3 short beeps
