Safety requirements regarding
Direct Audio Input (DAI)
● The safety of hearing instru-
ments with DAI (Direct Audio

the DAI is connected to mains-
operated equipment, this
equipment must comply with
IEC-60065, IEC-60601 or

there may be risk of impairing
the remaining hearing of the
hearing instrument user.
