Lock or unlock the keys

To lock or unlock the headset keys (also during a call),
briefly press the power key. When the keys are locked,

is displayed.

When you make or receive a call, the key lock remains off
until the call is ended, if you do not manually lock the keys
during the call.

When the key lock is on, the headset cannot be switched
off, and the following key symbols are not shown: answer/
end key, rewind key, forward key, stop key, and play/pause
key.

To set the headset to automatically lock the keys, see
“Automatic keylock,” p. 35.
