Talkabout radios have built-in Voice Operated Transmission (VOX) capability.
This means the sound of your voice activates transmission when the radio is
used with VOX accessories (sold separately).
The T289 also has iVOX (Internal Voice Operated Transmission), which allows
you to use the radio hands free without an accessory in place. Read the instruc-
tions below to activate the iVOX feature.
