# Using the Monitors - Texts window The Texts tab displays the most important current messages. These include the event that was entered last in the event record, the obstacles to ANS and engaging gears, the current operating condition of the transmission control unit, the currently active gear and the current retarder function.
| How to open Monitors - Texts:
Select Service > Monitor 1 > Texts in the main window. If there is communication with a connected transmission control unit, the current messages are displayed automatically. If communication with a transmission control unit is not possible, this will be indicated by a at the bottom right of the window: This message is also displayed when communication with a connected transmission control unit has been interrupted. For help in the event of communication problems, please refer to: Communication problems. Once you have eliminated the communication problems, click "Yes" if ALADIN is to re-establish communication with a transmission control unit. An existing communication is shown by the progress bar.
