### Contact Keys

The front Panel of the Telos Infinity INF-MXP-20 only contains contact keys and displays. Unlike the Telos Infinity INF-MP-16, there are no rotary encoders, loudspeakers, external XLR audio or GPIO connections(where fitted).

Pressing the key down enables the Talk function and pressing the key up enables the Listen function or answers an incoming call.

When used in combination with the INF-MP-16 Master Panel, the contact input volume can be adjusted by pushing the contact key up and then rotating the volume control on the Master Panel to vary the input level. See ["Adjusting the Listening Volume of an Individual Contact”](/v1/docs/v24-basic-operation#adjusting-the-listening-volume-of-an-individual-contact) in the INF-MP-16 section.

## Rear Panel

The rear Panel of the Telos Infinity INF-MXP-20 comprises of the following connectors:
