All other equipment shall:
a) protect the user from unintentional acoustic outputs exceeding those mentioned above; and
b) have a standard acoustic output level not exceeding those mentioned above, and automatically return to
an output level not exceeding those mentioned above when the power is switched o ; and
c) provide a means to actively inform the user of the increased sound pressure when the equipment is
operated with an acoustic output exceeding those mentioned above. Any means used shall be
acknowledged by the user before activating a mode of operation which allows for an acoustic output
exceeding those mentioned above. The acknowledgement does not need to be repeated more than once
every 20 h of cumulative listening time; and
d) have a warning as speci ed in Zx.3; and
e) not exceed the following:
1) equipment provided as a package(player with its listening device), the acoustic output shall be ≦ 100
dBA ,measured while playing the xed "programme simulation noise" described in EN 50332-1; and
2) a personal music player provided with an analogue electrical output socket for a listening device, the
electrical output shall be ≦ 150mV measured as described in EN 50332-2, while playing the xed
"programme simulation noise" described in EN 50332-1.
