■ Push to talk (PTT) calls
You can use the headset to make and receive push to talk (PTT) calls. To
use this network service, your phone must support it and the function
must be set to on in the phone. For more information on the PTT
function, contact your network operator or service provider and see the
user guide of your compatible phone.
To make a PTT call to the default PTT channel defined in your phone,
press and hold the middle of the volume key (while no call is in progress)
as long as you speak.
When you receive a PTT call while no call is in progress, the headset
beeps, and you start to hear speech from the channel. To answer and
speak to the listened channel within the time defined by the network
operator or service provider, press and hold the middle of the volume key
as long as you speak. To answer and speak to the default channel after
the time defined by the network operator or service provider, press and
hold the middle of the volume key as long as you speak.
