Remove the primary headset from the base and turn it ON.
Place the primary headset on your head (you’ll be listening for beeps).
Place the guest headset on the base.
The guest headset and base will flash purple.
When the guest headset begins to flash blue, lift it off of the base. It will go solid blue (turning ON automatically), and you’ll hear a series of beeps in your primary headset.
If you want to Mute the guest headset, simply press and hold either volume button on the guest headset for 1 sec. (Same to un-Mute).
