Thanks Paul,



That is true.



I will ask EWG to make that edit to what is in the Sandbox.



Actually I’ll do it here

When the dust settles EWG could you make the following change for 2.2-C in the Sandbox?
( in the HOW IT WOULD APPLY section

change

- Television sets would use (c – Any Connection with Adapter Avail)

to

- Television sets would most likely use either (c – Any Connection with Adapter Avail); or (d ? Public Display only).

Gregg: This version is much better. The only change I would propose is that a television should not be restricted to use only (c) because TV’s are usually intended to be located in a public location and thus should be able to use subparagraph (d). Therefore you should change the “How it would apply” section as follows:



- Television sets could use either (c) – Any Connection with Adapter Avail; or (d) ? Public Display only.



Thanks, Paul

Here is the CORRECT and CURRENT language for Version 3 (this matches what Rob sent out) along with the rationale.



Paul – does this address your problem/issue?

2.2-C - Audio Connection

When products provide auditory output beyond simple tonal feedback or signaling, one of the following must be true:

(a) Conforming Handset: Auditory output is available via audio transducer that is designed to be held up to the ear that meets 2.2-A (Magnetic Coupling), 2.2-B (Interference with Hearing Device), and 2.2-E (Volume - gain) and product does not require simultaneous use of keyboard; or

(b) Phone Jack: A standard 2.5mm or 3.5mm audio jack for headphones/headsets is provided or

(c) Any Connection with Adapter avail: Product is a not designed to be located in a public location and an adapter from the product's audio output format to a 2.5mm or 3.5mm phone jack is commonly available or available from the manufacturer.

(d) Public Display only: Product is designed for public audio or audio-video display only and there is a standard audio output on the product-system (which can be but does not need to be accessible to the public).

Note: RJ-9, RCA, USB, and Bluetooth connections all have commonly available adapters. Products (not designed for public locations) with these or other forms of audio connection that have adapters would meet 2.2-C-(c)

Note: Public Display systems need to meet other provisions in the guidelines including the ability to display captions and supplemental audio.



Rationale

- public phones have amplification and coupling and that meets needs of almost all users so shouldn’t need a jack

- audio output critical to use of kiosks and other products where user needs to hear information from product in order to use it. (either usual output or speech output for users who are blind)

- users should not be required to carry ‘all’ adapters with them so public systems should not require them to have an adapter to use the product (other than a simple 2.5 to 3.5 or 3.5 to 2.5 adapter)

- The RJ-9/RJ-10/RJ-11/4P4C (or whatever we end up calling it) connector has adapters as does Bluetooth and RCA and USB. Note was added since there was concern that unless in a note, purchasing agents may not recognize it as allowable.

- Addresses the issue of “private listening’ which is provided via the standard handset.

- Kiosks with keyboards usually require blind people to have both hands free.

- Addresses the key need for such a connection on kiosks – and that audio connection be in a standard form that people who are blind will have audio connector for.

- Addresses the need to have an audio connector somewhere on public Audio or Audio-Video systems so that public assistive listening device systems can be connected.



How it would apply

- Public phones would use (a - Conforming Handset)

- Office phones would likely use (c – Any Connection with Adapter Avail) but could use (b – Phone Jack)

- Computers with build in speech conversation could use (b – Phone Jack) which most have already or (c – Any Connection with Adapter Avail) including Bluetooth.

- Kiosks without keyboards could use (a - Conforming Handset) or (b – Phone Jack) or both.

- Kiosks WITH keyboards would have to use (b – Phone Jack) ----- or, of course, both (a - Conforming Handset) and (b – Phone Jack)

- Television sets would use (c – Any Connection with Adapter Avail)

- Public address systems and Custom Designed public Video Displays would use (d – public display only) which only requires an audio connection they will already have.

- etc.
