7.4.6 Step 6: Advanced device configuration (access protection/
operating code, saving the current setup)
Access protection
The access protection locks all the editable parameters, i.e. setup can only be accessed once
the 4-digit user code has been entered.
Access protection is not activated at the factory. However, the configuration of the device
can be protected by a four-digit code.
Activating access protection:
1. Call up the menu ‘Setup’ → ‘System’ → ‘Access code’
2. To enter the code with the ‘+’ and ‘-’ keys, select the desired character and confirm
with ‘E’. The cursor goes to the next position.
 Once the fourth position has been confirmed, the entry is accepted and the user
exits the ‘Access code’ submenu.
Once access protection has been successfully activated, the lock symbol is shown on the
display.
If access protection is enabled, the device locks automatically after 600 seconds if it
has not been operated in this time. The display switches back to the operating display.
To delete the code completely, use the ‘+’ and ‘-’ keys to select the "c" character and
confirm with ‘E’.
Saving the current setup/user setup
The current configuration of the device can be saved and is thus available as a specific
setup for a device reset or for a device restart. If you ordered the device with customized
settings which you specified, the preconfigured setup is also saved in the user setup.
Saving the setup:
1. Call up the menu ‘Expert’ → ‘System’ → ‘Save User Setup’.
2. Confirm by configuring ‘Yes’.
