Headset Jack
You can use this telephone hands-free when
you install a 2.5 mm headset (purchased
separately). To install, plug the headset into
the HEADSET JACK at the top of the handset.
While in headset mode, the volume of
headset is controlled by the telephone and
the handset’s earpiece and microphone
are disconnected.

Hearing Aid Compatibility
The handset has a special coil inside of it to
couple the sound to hearing aids equipped
with T-Switches/T-Coils.
Quick Reference Guide
A pullout quick reference guide is located on
the bottom of your C420. It will allow you
