Some Notes on Using Headphones

• To prevent damage to the cord, handle the headphones

only by the headset or the plug.

• The headphones may be damaged if the volume is too

high when they are plugged in. Lower the volume on the
KF-90 before plugging in the headphones.

• To prevent possible auditory damage, loss of hearing, or

damage to the headphones, the headphones should not
be used at an excessively high volume. Use the
headphones at a moderate volume level.
