7.1 Bluetooth registration
The headset is registered to a Bluetooth device by holding the BT button for 2 seconds (Fig.16). This will
enable pairing mode for the headset which then allows it to be discovered by other Bluetooth devices. The
RTX725x can store up to 4 paired BT devices’ information and remain connected to 2 of them at the same
time. In case of reaching the limit and pairing a new device after the 4 existing ones, the oldest device
information will be overwritten by the new agent.
Major mobile platforms are supported, such as iOS and Android.
