How to restore 18C (BTCK-18C) to default settings?

When the speakerphone is reset to factory default settings, all the paired mobile phone information will be erased.

  • 1). Ensure the speakerphone is in standby mode.
  • 2). Press and hold both “V+” and “V-“ buttons for about 10 seconds until the LED indicator flash blue and red 5 times.
  • 3). Then turn off the speakerphone. The speakerphone is back to original setting now.
