How do I check and set the terminal time?

One of the most common problems in connection with guest cards that no longer work is a shifted time setting. This often occurs when batteries on terminals have been changed or if there has been a power failure and a wall reader, for example at the entrance door, no longer accepts key cards.
To check and set the time yourself, the following instructions are available:

You need: An MDU110 and a privileged personnel transponder (e.g. the general card of the manager or building technician)

Checking the time on the terminal:

1. Select "Terminal Info" in the main menu and approach the terminal
2. You should now find the "Terminal time" by scrolling the adjusting dial

Setting the time on the terminal:

1. Check MDU (“handheld device”) time:
   1. Select MDU "Settings" > "Time"/"Date"
   2. Press Enter and adjust the time using the adjusting dial.
2. Select "Terminal" > "Time" in the main menu and approach the terminal
3. You will see the terminal time and MDU time on the display.
4. Press Enter to transfer the MDU time.
5. Briefly hold a privileged key (building technician or similar) to the terminal for authorization (terminal should beep once)
6. Hold the MDU against the terminal again to complete the data transfer.
7. The time should now be set.
