Question:

Can an FCC Part 68 compliant device employ a volume control allowing a gain greater than 18 dB without automatically resetting?
The FCC has instituted an expedited waiver process that allows phones to have an override switch to defeat the automatic reset provided all of the following safety considerations for advising the user are also implemented:

(1) The volume reset override switch shall be labeled as such and located on the telephone in such a way as to not be accessible to accidental engagement;

(2) a bright indicator light shall be prominently displayed on the front of the telephone and shall light up when the override is engaged and the telephone is placed in an off-hook condition;

(3) next to the light shall be a warning that the amplification is at a high level;

(4) a caution on the use of the volume reset override switch shall be included in the users' manual; and

(5) the telephone includes a warning printed in Braille that can be securely attached to the back of the handset, or, if the telephone has only a headset, above the dial buttons, to indicate that a high volume setting may be engaged.

To request such a waiver, submit a written request to the FCC testifying to the above.
For more information see FCC document DA 01-578, “Memorandum and Order in the Matter of Tandy Corporation, Walker Equipment Company, Ameriphone, Inc., and Ultratec, Inc., Request for Wavier of Volume Control Reset, 47CFR Section 68.317(f).” Paragraph 15 provides detail on requesting a waiver and paragraph 17 provides an official statement of the above requirements.
