6.8 PIN code
The projector can be locked by a PIN (Personal Identification Number) code to control
access. The PIN code is 4 digits, and if the PIN code is activated, you must enter the
correct code to unlock the projector. Factory set PIN (1234).
To activate, deactivate or change the PIN code, see the SETTINGS > PIN CODE sub menu.
If an incorrect PIN code is entered, you may try again two times. If you fail three times
in a row, entering a PUK (unlock) code is needed. The PUK code is supplied with the
product.
If you also fail three times with the PUK code, the projector locks up permanently, and
can only be unlocked by a special service unlock code.
To access this code, you will need to contact your dealer or a service station. The service
unlock code will be generated based on a secure, encrypted number that is produced by the
projector itself. The projector will produce a new number every time.
In order to unlock the projector via a dealer/service station, proof of ownership must
be provided by the customer.
