Replacing the ear
pads
When the ear pads become dirty or
damaged, you can get replacements
from your Sony dealer. Replace them
as illustrated below.
1Remove the old ear pad by pulling
it out of the groove on the housing.
2Place the new ear pad on the
housing and insert the edge of the
pad onto the groove as illustrated.
Make sure that the entire edge of the
ear pad is securely inserted into the
groove.
Listening to a program
• As MDR-IF320RK2 Cordless Stereo
Headphone System is not affected by
the memory effect of Ni-Cd battery, it
is suggested that the headphones be
rested on the transmitter whenever
not in use so that headphones’
battery is always charged.
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.
The effective areas
of the transmitter
The illustration below shows the
approximate area covered by the
infrared rays emitted from the
transmitter.
Notes
• If you use the headphones at too great a
distance from the transmitter, you may hear a
hissing noise and if there is an object between
the receiver and the transmitter, the sound may
be interrupted. These phenomena are inherent
to infrared ray communication and do not
mean that there is a problem with the unit
itself.
• Do not cover the infrared sensors with your
hands or hair.
• 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 diagrams, the transmitter can
be placed in the front, behind or by the side of
the listener.
