If audio output is provided, provide an industry standard audio connector to allow for private listening. Provide the ability to interrupt, pause, and restart the audio.
Rationale
When a product uses audio to communicate important information, individuals using personal headphones, amplifiers, audio couplers and other audio processing devices need a place to plug the device into the product in a standard way. This gives the user the ability to listen privately to the information.
Development techniques
The following techniques are the minimum required to meet Checkpoint 4.2 from the IBM Hardware Self Contained, Closed Products Accessibility Checklist:
- Provide a standard audio connector so individuals using personal headphones, amplifiers, audio couplers and other audio processing devices can plug these devices into the product in a standard way.
- Provide the ability to pause, restart and interrupt the audio output.
Testing techniques
Test the hardware to ensure that it complies with accessibility requirements.
Tools
No tools are needed to test this checkpoint.
