The HeadONE is manufactured with an accelerometer built within; which means the unit can detect if it is positioned horizontally (Pan) or vertically, on its side (Tilt).
Therefore, two HeadONE devices may only connect to each other while they are placed in the pan and tilt positioning.
If both devices are laying horizontally then one will not be able to connect as Tilt, the same as if both HeadONE devices were positioned vertically, one of the products would not connect unless placed in the Pan positioning.
Once you’ve placed the HeadONE devices as indicated above, power up each unit, but please wait for each unit to beep.
Only after you hear beeps from each HeadONE individually should you press the "OK" button in order for the system to combine the HeadONE products together.
IMPORTANT: if you press the "OK" button before hearing each unit's connection indicator (the beep), the edelkrone app will not recognize the remaining units to pair the products together.
If the app does not combine one of the devices after you've heard the beep sounds emitted from your unit, please power cycle each device and terminate the edelkrone application to restart the process again.
The edelkrone App is accessible at Apple's App Store or the Google Play Store.
