3 Playing music
1. When power is ON
When the power switch is set to ON, the power indicator
lights green, and the noise-canceling function operates,
allowing you to listen to music without excessively raising
the volume, thus eliminating the need to raise sound volume
excessively, and reducing disturbance to nearby people.
2. When power is OFF
When the power switch is set to OFF, the noise-canceling
function stops, and the unit can be used as ordinary
earphones.
3. When the monitor button is pressed
While the monitor button is held depressed, playback sound
is muted and the noise-canceling function is temporarily
stopped, thus allowing you to hear ambient sounds without
removing the earphones.
* This function is enabled only when the power switch is set
to ON.
4 Following Use
When not using the earphones, set the power switch to OFF.
