Factory Restore a Microphone Adapter

If your microphone adapter isn’t functioning correctly, you might need to factory restore it. A factory restore completely erases the microphone adapter’s flash memory and restores it to the latest major software version (x.0).

The factory restore button is on the side of the microphone adapter.

Procedure

  1. Disconnect the power supply to turn off the microphone adapter.
  2. Optional for USB flash drive method: Download the software package you want to install from Polycom Support and save the package to the root directory of a USB flash drive. Insert the USB flash drive into a USB port.
    Note: Poly recommends formatting your USB flash drive with the FAT32 file system.
  3. Insert a straightened paper clip through the factory restore button pinhole.
  4. While continuing to hold the restore button, reconnect the power supply to turn the microphone adapter on.
  5. Hold the restore button for 10 more seconds, then release it.
    The microphone adapter LED blinks green and blue during a factory restore.
    Note: Don’t power off the microphone adapter during this process. It restarts when complete.
