The Effective Areas Of The Transmitter - Sony MDR-IF630RK Manual De Instrucciones

Mute function
If a hissing noise is heard when the infrared rays
are obstructed, or the headphones are used
outside of the effective range (see right column),
the mute function will be activated and the
sound will not be heard from the headphones.
To restore the sound, move nearer toward the
transmitter or remove the obstruction.
When no audio signal is received for
more than approximately five minutes
The transmitter will be turned off automatically.
When an audio signal is intermittent or a
low-level audio signal continues for more
than approximately five minutes
The transmitter may be turned off automatically.
In this case, turn up the volume of the connected
equipment while turning down the volume of the
headphones.
After listening to a program
Take the headphones off and rest them on the
transmitter. Then turn off the connected audio/
video equipment. The transmitter power will be
turned off automatically if no audio signal is
input from the audio/video equipment for more
than approximately five minutes.
Note
The infrared emitters light up when the transmitter is
turned on. The brightness of the emitters may not be
uniform, however, this is not a malfunction.

Notes
• This system utilizes infrared rays for communication
so noise (hissing) can be heard from the headphones
as you move farther away from the transmitter. The
sound will also be cutoff and noise will be heard if the
infrared rays are blocked. These are characteristics of
infrared ray communication and do not indicate
malfunction.
• The infrared rays will not penetrate walls or opaque
glass, therefore, be sure to stay within sight of the
transmitter.
• When you use the headphones inside the area
illustrated in the diagram, the transmitter can be
placed in the front, behind or by the side of the
listener.
• The sound you hear varies according to your position
and the transmitter position. Try finding a position
which yields the best sound.
• Do not cover the infrared sensors with your hands or
hair.
