3. Pairing
Please follow these guidelines carefully for the successful pairing:
*Products are pre-paired from the factory (except X1) and ready to use without manual
pairing.
*Ensure headsets have the same rmware version before pairing, or pairing will not be
possible.
*Please restart all headsets after pairing to save the pairing setup. On the next startup, the
headsets will auto-pair based on the previous setup. If no need for re-pairing to change
the Master or build the group, please do not manually re-pairing to prevent disrupting the
pairing conguration while using.
