With the Walker powered on (and the status lights either flashing or solid), press the Power button once. The Walker will enter 'pairing mode' for 10 seconds and the blue 'Reader' light will begin to flash rapidly.
While the blue ‘Reader’ light on the Walker is flashing, press the centre (blue) button on the Reader. The Reader will show an ELEMENTICE™ logo on the screen as it boots, and then connect to the Walker.
When connected, the blue ‘Reader’ light on the Walker will stop flashing and go solid to indicate a connection. Meanwhile, the Reader will display useful information as in the video above.
If you need to disconnect a Reader, press the power button on the Walker again. The Walker will drop the current reader connection and enter pairing mode again. You can either reconnect with the same Reader by pressing the centre Reader button again (while the blue 'Reader' light is still flashing quickly) or pair with a new Reader by pressing that Reader’s centre button instead.
