Headset connector

The headset connector is the input jack for the optional
hands-free headset. The headset includes an earbud and

without using your hands.
Before connecting the headset, gently pry open the input jack
cover to expose the connector inside.

Microphone

The microphone, located just beneath on the keypad, is used
for conversation, voice setup, and recording voice memos.
