Direct audio input (optional)
Use of direct audio input (DAI), which enables a direct connection of the hearing instruments to
items such as television, radio, and remote microphones, may increase speech understanding
for some individuals. The sound source is connected to the hearing instruments by a cable or
a wireless FM system to the audio boot. This accessory connects to the bottom of the hear-
ing instruments, and once properly clicked into place, the hearing instruments switch to DAI
automatically.
