C4230 Base Design
Visual Ringers
Flash to notify the user that the
phone is ringing.
The visual ringer is also used as
part of the design to emphasize
Clarity’s technology by drawing
attention to the earpiece speaker.
The “Talk” and “Speakerphone”
button will also light up, notifying
the user which button to use to
answer the call.
The visual ringers on the base are
sunken to allow the user to easily
access the handset.
C4230 Handset Design
Earpiece Shape
The earpiece is shaped
specifically to cup the user’s ear,
accomplishing a “custom fit”
experience.
Not only comfortable, but
functional. The “cup” forms a
sealed chamber around the ear for
better sound. This enables the
phone to work extremely well with
a hearing aid, reducing
background noise and feedback.
