While encouraged by the adoption of a uniform minimum sound alert standard, the WBU continues to believe that: 1) the proposed minimum sound standard is too low for safety; 2) the AVAS should remain on while the QRTV is active but stationary; and 3) the regulation should prohibit manufacturers from providing a means of pausing the alert sound.

This proposal can be considered as the first phase of the regulation. In response to concerns raised by the World Blind Union, GRB agreed to extend the mandate of the informal working group that developed this text in order to consider further measures to address the WBU concerns.
