Instant Link mode

There can be a maximum of 6 headsets paired together for intercom in instant link mode. No matter what is the number of headsets to be paired, the pairing procedure is all the same. There will be one headset that acts as the active pairing device while all other headsets act as passive pairing devices. The following are two examples to illustrate pairing 2 headsets and pairing 6 headsets.
After the pairing is completed, the next time when any headset of the pairing group activates the intercom, the group intercom commences immediately. Even if any headset of the group leaves, the other group members stay on the intercom without being affected. When that member rejoins the group again, it will resume the intercom automatically.
The pairing data of instant link mode is saved after power off, so there is no need to go through the pairing procedure while powering on again. However, if there are new members that join the group intercom, the pairing procedure needs to be executed again.
