Using The Headphones; Troubleshooting - Denon AH-NC600 Manual Del Usuario

Dry battery replacement period
When the battery wears down, the
indicator will turn off or flash. Replace
the old battery with a new one.
Dry battery duration
When using an alkaline dry battery, the duration is approximately
60 hours.
This varies with the conditions of use.
Cautions on the battery
• Be sure to turn the AH-NC600's power switch off when
replacing the battery.
• Use a R03/AAA alkaline battery in the AH-NC600. Using other
batteries may result in a shorter operating time.
• Use a new battery. Using an old battery may result in an
extremely short operating time.
• The included battery is only meant for checking operation.
• Do not attempt to recharge the battery.
Doing so could result in damage or leakage of battery fluid.
Also do not heat or disassemble the battery or dispose of it in
flames or water.
• Remove the battery when not using the AH-NC600 for extended
periods of time.
• If the battery fluid should leak, carefully wipe the fluid off the
inside of the battery compartment and insert new batteries.

Using the headphones

Preparations
About the ear pieces
Foam type: Material offering a good fit in
the ear and little affected by
surrounding noise.
Regular type: Material little affected by sweat or
fat. Select the ear pieces providing
the best fit from among three
sizes: S, M and L.
NOTE:
• Fit the ear pieces securely on the nozzle of the headphones.
• Choose ear pieces that fit in your ear. If the ear pieces do not fit
properly, the noise cancellation effect will be weak, the sound
will leak out or the bass will not be audible.
• The ear pieces may deteriorate after long term of use or
storage.
About foam type ear pieces
n Mounting
Pinch the tip of the ear piece and attach it to the headphone's
nozzle while turning.

Indicator
size after 15 to 30 seconds.
• Do not let Foam type ear pieces get wet. Moisture will
accelerate their deterioration.

• You may not be able to use with some portable and other
devices equipped with a digital amplifier.
With the AH-NC600 power switched off, you can use as
normal headphones.
About the RESTORER function
Such compressed audio formats as MP3, WMA (Windows
Media Audio) and MPEG-4 AAC reduce the amount of data by
eliminating signal components that are hard for the human ear to
hear. The RESTORER function generates the signals eliminated
upon compression, restoring the sound to conditions near those
of the original sound before compression.
n Operations
Set the switch to "RESTORER".
• The noise cancellation function and the restorer function turn
on, and the indicator lights white.
Handling the cords
• Adjust the position of the slider to take up any slack in the right
and left cables.
• Use the clip to fasten the control box to a pocket on your
clothes, etc.
