To enable the active noise-canceling system on the NC500TFC, the batteries must be installed as follows:
• Batteries are located behind the battery compartment cover on the front of the left (L) ear cup.
Identify the down arrow (picture) before attempting to open battery compartment. Do not
attempt to open the right-side (R) ear cup.
• To install the batteries, remove the battery compartment cover by pressing down lightly
with both thumbs on the battery compartment cover, and then, gently slide the removable
lid in the direction of the arrow.
• Insert two (2) AAA batteries in accordance with the polarity symbol (+) or (-) marked in the
battery compartment.
• Replace the battery compartment cover with the down arrow on the bottom of the ear cup.
Simultaneously press down lightly and slide the battery cap upwards to lock in place.
• To enable the NC500TFC’s noise-canceling system, turn the power switch to the on position.
Note that the power indicator LED should light green.
• The active noise-canceling system of the NC500TFC does not remove all ambient noise. It is only
eective at reducing loudness of certain types of ambient sounds (typically in the bass frequencies).
Also, some high frequency “white” noise may be added when the noise-canceling system is active.
• Although it varies by usage, battery life averages 35 hours. With the headphone’s noise-canceling
turned on, the LED indicator will dim when approximately 30 minutes of battery life remains.
• Rechargeable batteries can be used with the headphone; however, battery life may vary. In addition,
the power indicator LED is not calibrated for rechargeable batteries, and therefore may not be a reliable
indicator of battery output.
• The in-line volume control has no eect on the noise canceling system.
• Identify the left (L) and Right (R) designations located on each side of the headband. The headband
adjusts for a comfortable t by sliding the top and side of the headband apart as seen in the photo.
• Place one hand on the top of the headband and the other hand on the side of the headband and
pull in opposite directions to adjust the size of the headband, and then, place them on your head.
• Now you can make minor adjustments to create a comfortable t.
Note: Pulling down aggressively on the ear cups can damage the headphone. You may want to make several small
adjustments to achieve a perfect t. Always wear the headphones so the cable is positioned on your left.
For protection during travel or storage, the headphone
folds at inside its hard shell protective carrying case.
To store the headphones, do the following:
1. Identify the left (L) and Right (R) designations located
on each side of the headband.
2. Hold the headphones with two hands with the Left (L) ear
cup in your left hand. You should be able to see the power
indicator LED and the ON/OFF switch.
3. Gently turn the ear cups away from you and in opposite directions to
place the headphone in its protective carrying case. If the ear cups do not
turn, stop immediately. Forcing the ear cups may cause them to break.
4. Zip closed the carrying case to protect your headphone from damage.
