Chapter 4 - Operating instructions
4.9 Access and security
4.9.1 User level
The user level function in the
SECURITY
menu restricts access, in varying degrees, to the
operational controls of the camera. You can only access the functions of the
SECURITY
menu
with an owner's card or the PIN code of the camera.
4.9.2 Selecting the user level
There are four user levels: user0, user1, user2 and user3. The purpose of the user levels is to
restrict the set of functions which can be changed by whoever is using the camera. In this way
a more centralized and uniform control can be achieved and the danger of the camera operator
accidentally changing critical functions while shooting is reduced.
User level 0 is a special protection level which locks most of the operational controls of the
camera. Use this level to ensure that a camera that has been set-up is not tampered with. User
level 0 is not normally used for operational purposes as it is too restrictive for normal
circumstances. The recommended minimum user level is 1. For full control set the level to 3.
When you switch off the power, the access rights that were obtained by the use of the PIN
code are disabled and the camera starts at the assigned user level when switched on again.
4.9.3 Disable camera
The disable camera function is a protection function which prevents unauthorised interference
with the camera and provides an additional level of security. Setting disable camera to
ON is
similar to using User level 0 to protect the settings of the camera.
4.9.4 Camera cards
Three camera cards are delivered with each camera. There are two user's cards and one
owner's card.
