Reset the CR3171

If a configuration issue occurs, the device can be reset by following these steps:

Steps to Reset the Device

  • Disconnect the 14-pin connector.
  • Press the reset button using a paperclip or a similar small object.
ℹ The internal Super Cap will provide the power for the reset procedure, therefore, even without power supply the LEDs will light-up as reset feedback.
⚠ Important Notes:
The reset process depends on the device's internal supercapacitor. Ensure the supercapacitor is sufficiently charged by connecting the device to a power source for at least 5 minutes before initiating the reset.


Reset Button Functions

The function of the reset button depends on how long it is pressed. Refer to the following descriptions for each duration:

  • Press and hold for 0 to 5 seconds:
    Performs a power reset. The red LED blinks rapidly (950 ms on, 50 ms off).
  • Press and hold for 5 to 10 seconds:
    Resets the bridge mode settings. The red LED blinks at an even rate (500 ms on, 500 ms off).
  • Press and hold for 30 to 40 seconds:
    Performs a factory reset. The red LED blinks slowly (250 ms on, 750 ms off).
  • Press and hold for 45 to 100 seconds:
    Activates recovery mode (⚠ currently not yet available on CR3171). The red LED blinks very briefly (5 ms on, 955 ms off).


Post-Reset Procedure:

If the button is pressed for more than 45 seconds:

  • Disconnect power and leave the device unpowered for 5-10 minutes.
  • Reconnect power and turn the device back on.

If the button is pressed for less than 45 seconds:

  • Simply reconnect power and turn the device back on immediately after releasing the button.
