Restore to Factory Defaults
If the control system is no longer communicating via USB or Ethernet, use the following
procedure to restore the device to its factory default settings.
NOTE: This procedure erases the control system’s firmware and reinstalls it. If problems
persist before a SIMPL program is loaded, contact Crestron True Blue support via phone,
email, or chat as described at www.crestron.com/Support. If the system locks up after a
SIMPL or SIMPL# Pro program is loaded, there is likely an issue with the program.
1. Remove all wired connections from the control system.
2. Reconnect the power supply.
3. Use a small, pointed object (such as the tip of a pen) to press and release the HW-R
button on the front of the control system.
4. Wait for the MSGor ACQUIRELED to light on the control system roughly one second
after pressing the HW-R button.
5. Use a small, pointed object (such as the tip of a pen) to quickly press the SW-R button on
the front of the control system five times, with under a one-second gap between each
press.
6. Wait up to 5–10 minutes for the self-recovery process to complete.
7. Attempt to make a connection to the control system over USBor Ethernet as described in
Establish Communications (on page152).
8. Once the device has been discovered, use the Text Console tool in Crestron Toolbox to
check for a prompt. The standard device prompt should display.
NOTE: Repeat the procedure if the first attempt does not correct the issue. If the
control system is still unresponsive, contact Crestron True Blue support for assistance.
