The managers panel on a Tynetec XT2 system is designed to be the managers interface to the system, showing things such as the Im OK function, faults, event logs and live information such as calls in progress. You can also program and de-program wireless devices to the system through the managers panel.

Managers Panel is asking for a password
The managers panel is based on Windows 10 and as such, carries out security updates from time to time. This can sometimes result in the panel showing a Windows 10 Login screen requesting a password. The simplest way to resolve this is to reboot the panel, at which point it will bypass the login screen and return to the Tynetec interface.
Step 1
Underneath the managers panel you will find two plugs. Unplug the black power cable by pulling it down towards the floor
Underside of Tynetec XT2 Managers Panel
Step 2
Leave the managers panel unplugged for 10 seconds
Step 3
Reinsert the power cable. Place one hand on top of the panel to prevent it from coming off of its mount, then using the other hand, reinsert the power cable.
The panel will now take about 2-3 minutes to go through its boot up procedure. Please do not touch it in this time. Once this procedure is finished, you will be presented with the normal Managers Panel Interface.
Managers Panel shows "Faults Exist"
The Faults Exist indicator on the home screen of the managers panel will show any time there is a parked unit, or a fault on the system

A Parked unit is a speech module within the building that has been disabled. It will not function, nor will any device connected to that speech module.

Step 3
Dial 1008* on your phones keypad. Listen carefully to the following information. The phone will now list off any faults, or parked modules. The list will finish when you hear the "Ready" prompt again.

If you have faults on the system, please ensure you raise these with Sentinel for an engineering attendance.
