Califone Headphones 2985PG User Manual

TM  
Sound Alert  
Monaural Headphone  
The Sound AlertTM headphone  
visibly signals to students and  
teachers when the headphone  
volume is louder than the  
American Speech-Language-  
Hearing Association recommended  
85dB level.  
When the volume that is played  
through the headphone exceeds  
85 decibels, a bright red warning  
light on the earcup turns on,  
alerting both the teacher and  
student about an unsafe sound  
level requiring adjustment.  
Having an appropriate volume  
level pointed out will help teachers  
and students learn safe and  
lifelong listening practices,  
beginning in the classroom,  
learning center, or school library.  
According to a March 2006  
national poll commissioned by  
the American Speech-Language-  
Hearing Association, 40% of  
students reportedly set their  
music players’ volume above 85 decibels, which is the level hearing experts recommend not be  
exceeded. If music can be heard coming from a student's headphone, the volume is too loud and  
the student is at risk of experiencing hearing loss.  
Hearing loss can lead to many problems in school including: difficulty with  
academic achievement in language arts, vocabulary, arithmetic, and problem  
solving. Students with hearing loss score lower on achievement tests, and have  
greater needs for special education or extra support in the classroom.  
This durable headphone is based on the rugged Califone monaural headphone,  
which is the educator’s standard for listening centers, ELL and ELD and other  
language learning activities.  
The Sound Alert headphone can be used as a normal headphone  
without charging the battery, but the warning LED feature will  
not operate. The headphone saves power by shutting off when  
no audio signal is present for 60 seconds and will power on  
automatically when there is an audio signal present.  
Also available is the 10-position Sound AlertTM monaural jackbox.  
With the sound level monitored from this jackbox, the volume  
from up to ten attached headphones (not needing to be the  
2985PG) can be adjusted to the safe 85 decibel level.
