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.
Ordering a Headset: In the event you
wish to purchase a headset for your Clarity
420, please contact Plantronics at
1-800-544-4660 for location near you.
We recommend using the Plantronics
M110 or M130 headset.

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
to quickly reference key operations of your
phone and also record the frequently dialed
numbers and emergency numbers you may
have stored into your telephone.
