Type your message and press **Enter** to send. The DM is sent encrypted directly to that contact (or flooded if no direct path is known). After sending or cancelling, you're returned to the contacts list.

+Select a **Repeater** contact in the contacts list and press **Enter** to open the repeater admin screen. You'll be prompted for the repeater's admin password. Characters briefly appear as you type them before being masked, making it easier to enter symbols and numbers on the T-Deck Pro keyboard.
+
+After a successful login, you'll see a menu with the following remote administration commands:
+
+| Menu Item | Description |
+|-----------|-------------|
+| Clock Sync | Push your device's clock time to the repeater |
+| Send Advert | Trigger the repeater to broadcast an advertisement |
+| Neighbors | View other repeaters heard via zero-hop adverts |
+| Get Clock | Read the repeater's current clock value |
+| Version | Query the repeater's firmware version |
+| Get Status | Retrieve repeater status information |
