can be easily removed and taken away from the PBX by a third party. Therefore, do not allow
unauthorised access to prevent data leakage.

Do not remove the SD Memory Card while power is supplied to the PBX. Doing so may cause the PBX
to fail to start when you try to restart the system.
•
To prevent data leakage, render the SD Memory Card physically unusable before disposal.

Use only the SD Memory Card included with the PBX, or a Panasonic optional upgrade SD Memory
Card.
