In the interest of all users of the computer systems, we would like to point out that the following rules must be observed:

The doors to the computer rooms must be kept closed at all times. When you enter or leave the room, you are responsible for ensuring that the door is closed afterwards.

Under no circumstances may you open the door for unauthorised persons. Make sure that there are no unauthorised persons in the room.

Never force the door open. Use your magnetic card to open the door. Any other behaviour could be regarded as an attempt to break in.

Windows that have been opened for ventilation must always be closed before leaving the room. The last person to leave the room is responsible for this.

After 6.00 p.m. and at weekends, please inform the porter immediately if you notice any theft. In unusual situations, such as a system crash, please call 3123 and leave a message on the tape recorder. You will find a telephone in the lift in the stairwell, for example.

It is in our interest to give all users as much freedom as possible when using the computer systems. However, this also means that users must behave responsibly. Prevent theft and vandalism in order to preserve your own and other people's ability to work.
