Using a Headset
For phone calls, use the remote Walkie-Talkie
button to answer calls, switch between calls, and
end calls. Hold the remote Walkie-Talkie button for
less than 2 seconds to answer calls and switch
between calls. Hold the remote Walkie-Talkie
button for more than 2 seconds to end calls.
For Walkie-Talkie calls, Group Walkie-Talkie calls,
and Talkgroup calls, use the remote Walkie-Talkie
button as you would the Walkie-Talkie button on
your phone.
Note: When using a headset, the Walkie-Talkie
button on your phone works the same way
as when you are not using a headset.
Walkie-Talkie sounds will be heard
through the headset.
