Clarity® Power Technology
With the Clarity Power feature the high frequency sounds are amplified more than the low frequency sounds so that words are not just louder, but clearer and easier to understand.
Clarity Power ON/OFF Switch
With the Clarity Power feature ON, the high frequency sounds are amplified more than the low frequency sounds (Clarity Power). The Clarity Power is introduced automatically with volume increase. Clarity Power OFF provides no frequency shaping, but simply deliv- ers the loudest output possible.
Clarity Power BOOST Button
The C500 has a BOOST 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 default state of this button is determined by the Boost switch (back of base of unit, see below). During a call, the CLARITY POWER button can toggle the Clarity Power function on or off according to the user’s needs. The BOOST button will reset automatically every time the phone is hung up for at
least 5 seconds (if Boost switch is in OFF position – see BOOST ON/OFF switch description below). This is done to protect users of the phone who may not need the powerful amplifica- tion of the C500. The BOOST button will light RED to indicate the Boost function is active.
Warning: Volume may be at a high level. To protect hearing, lower the Clarity Power Control Dial before using the phone.
