Hearing aid users experience reduced interference on new C4220, C4230 phones, Walker handsets 
Chattanooga, Tenn. – Clarity, a division of Plantronics (NYSE: PLT), announced that its C4220 and C4230 amplified telephones, as well as its Walker handsets comply with the TIA-1083 standard—a performance benchmark for digital cordless phones. Hearing aid wearers using Clarity’s TIA-1083 compliant phones will experience significantly reduced problems with audio interference during conversations.
“Meeting the TIA-1083 standard reinforces Clarity’s commitment to improving the lives of millions with hearing loss,” said Carsten Trads, president of Clarity. “As technology advances, we integrate new and innovative improvements so our products always perform at the highest level. Soon, integrating this standard will not only be a part of our C4220, C4230 and Walker handset lines, but will become routine in Clarity’s future product development.”
The TIA-1083 standard was designed by the Telecommunications Industry Association in conjunction with the Hearing Loss Association of American (formerly Self Help for Hard of Hearing People). Prior to publication in 2007, hearing aid users were prone to interference while using digital cordless telephones. Now, manufacturers like Clarity can turn to the TIA-1083 standard as a benchmark to improve conversations for people with hearing aids.
The Clarity C4230 offers the same ergonomic design, functions and 50 decibel amplification with DCP as the C4220, but includes an amplified speakerphone in both the handset and the base. Also, a variable speed playback digital answering machine allows users to check messages through the portable handset or the amplified speakerphone and to slow down message recordings to make them easier to understand. The C4230, which is recognized by the Arthritis Foundation’s Ease-of-Use Commendation program, can be purchased online for $269.95 at www.clarityproducts.com.
The Clarity C4220 uses patented Digital Clarity Power ™ (DCP) to intelligently amplify incoming sound up to 50 decibels, making conversations not only louder, but clearer and easier to understand. And the handset’s ergonomic design, inspired by an ice cream scooper, is easy to grip. It also features a handset speakerphone, adjustable volume, tone and balance, as well as, visual and tactile ring indicators that help people with low vision. It can be purchased online for $199.95 at www.clarityproducts.com.
Clarity offers a variety of handsets, both pre-made and customized, under the Walker brand name.
