Note about Safe Listening Practices

Califone is proud to collaborate with the American Speech-Language-

Hearing Association (ASHA) to promote the safe use of personal audio products in the classroom. These two guidelines will help students use audio technology responsibly:

• Lower the volume

• Limit listening time

Califone also recommends using headphones with ambient noise reducing earcups.

School Applications for the

Active Noise Canceling Headphones

The Califone NC500TFC Active Noise Canceling Headphone can be used on its own for creating the quietest of individual settings such as during high stakes testing, or connected to an audio source for optimal sound quality.

• When connecting the NC500TFC to an audio source for use as a pair of headphones, plug the included 3.5mm end of the connecting cable into the headphone and other 3.5mm or ¼” plug on the other end into the audio source (CD or

MP3 player, computer or other multimedia player). When used this way, the integrated LINX AUDIO™ system automatically enhances harmonics in the audio signal to increase clarity and richness of the sound. Note: The batteries do not need to be installed for the NC500TFC to be used as headphones.

• To enable the active noise canceling system for additional reduction of ambient noise, the power must be switched on.

The active noise canceling system can work simultaneously while using the headphone to listen to an audio source.

• Without power or a sound source, the headphone may act as a passive ambient noise-reducing headset.

Setup & Operation

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.

Notes

• The active noise-canceling system of the NC500TFC does not remove all ambient noise. It is only

effective 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 effect on the noise canceling system.

Adjusting the Headphone for Comfort

• Identify the left (L) and Right (R) designations located on each side of the headband. The headband

adjusts for a comfortable fit 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 fit.

Note: Pulling down aggressively on the ear cups can damage the headphone. You may want to make several small adjustments to achieve a perfect fit. Always wear the headphones so the cable is positioned on your left.

Travel & Storage

For protection during travel or storage, the headphone folds flat 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.

In addition to personal or small group sound fields in the classroom, teachers and administrators are also turning to the use of classroom-wide sound fields. Numerous studies verify the educational benefits of sound field amplification systems, including increased on-task behavior and student attention to oral instruction, improved comprehension among ELL students, and reduced vocal strain and fatigue for teachers.

PA-IRSYS

As administrators strive to meet NCLB goals, they must also address groups with diverse needs such as ELL, ESL and students with special needs. Teachers need to convey audio information to students in all of these groups in a clear, concise manner.

The Classroom Infrared Audio System can help teachers teach and how students learn. The system includes two array speakers for superior sound distribution (or an optional four speakers for larger rooms).

Array speakers (commonly seen at concerts) focus a narrow band of sound directly at the students instead of bouncing it off the walls in a random and confusing fashion. This enhanced sound projection improves the critical signal-to-noise ratio, therefore improving the clarity and intelligibility of the amplified audio. Also included are two wireless mics (one for the teacher and a hand held mic for shared student use), so all speakers in the class are assured of being heard, even when the system is connected for teleconferencing.
