Supplier Best Practices

Below are some suggested best practices for suppliers of wireless devices from CTIA’s working groups.

Hands-Free Operation

  • Products designed and marketed for use in a vehicle should be “hands-free.”
  • Any product or software that converts a device for use in a vehicle should include all equipment necessary for “hands-free” operation.
  • Devices should include an insert in the packaging directing users to a toll-free number to purchase hands-free devices for the handset.

Audio Accessibility

  • Devices with speech or audio capabilities should include a port for external audio devices, including earphones, headsets, car kits and TDD/TTY devices.
  • Devices with speech or audio capabilities should also support hands-free speech.

TIA Safety Information

  • The Telecommunications Industry Association (TIA) Ad Hoc committee on product information created ”TIA Safety Language” in 1997 to inform users of safe use of their wireless devices, particularly those pertaining to pacemakers, hearing aids and other medical devices.
  • Use of TIA language is encouraged. 

SAR & FCC ID Labeling

  • Wireless devices should detail in the packaging, in consumer-friendly language, the highest Specific Absorption Rate (SAR) reported to the Federal Communications Commission (FCC) Grant of Equipment Authorization, relating to the amount of radio frequency (RF) energy is absorbed by the body when using the handset.
  • SAR Information should also be available on the manufacturer’s website.
  • Devices should display the FCC ID labeling on the outside of the phone’s packaging.
  • The U.S. Food and Drug Administration (FDA) and the FCC answer common consumer questions on RF energy and wireless devices on this consumer website. The website is revised to reflect current issues and information.

Protecting Against Accidental 911 Dialing

  • To protect consumers against accidental 911 calls and prevent the waste of first responder resources, wireless devices should not be pre-programmed to dial 911 with a one-touch dialing feature.
  • However, users may program their own one-touch dialing feature for 911 on their own device.
