Earlier this year, I previewed the C4230 first hand at Clarity’s world headquarters located in Chattanooga, TN.

The C4230 is a 5.8GHz cordless amplified phone, branded Clarity Professional.

ERGONOMICS
Separation of Functionalities:
Separating the different functions of the phone will help instruct the user as to where to interact with the phone to access the different features.
Because the C4230 is a feature rich phone and our target market is not familiar with complicated technologies, our products must accommodate hard (software independent) and direct buttons without looking overwhelming.
Dividing the phone into thirds also offers a visually pleasant composition.
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.
Earpiece Shape:
The earpiece is shaped specifically to cup your 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.
The speaker cutout is in the form of the Clarity logo to signify that the technology and sound that enables you to finally hear a loved one on the phone comes from Clarity.
