Digital Clarity Power Technology

With Digital Clarity Power, the high frequency sounds are amplified more than the low

frequency sounds so words are not just louder, but clearer and easier to understand. It

also provides intelligent amplification to make soft sounds audible, while keeping loud

sounds bearable.

BOOST - Clarity Power On/Off

The C4210 has a button that controls the loudness of the receiver. Once the BOOST

button is pressed, an extra level of amplification is added over the entire range of the

volume control.

The TALK button will light ORANGE to indicate the CLARITY POWER feature is

activated.
