Important Safety Information
1. Read these instructions.
2. Follow all these instructions
3. If you hear ringing or experience pain or discomfort in your ears during or after using any headphone audio product, that is a sign you
are listening too loud. When your ears are exposed to high volumes (in excess of 85dB) for over an hour, you may be permanently
damaging your hearing.
4. Turn down your listening device’s volume to zero before you insert the Sangean headphones and turn on the device.. Once you have
the headphones in, gradually increase the volume to a comfortable, moderate volume.
5. Clean your headphones with antiseptic wipe. This improves the acoustic quality of your headphones.
6. NEVER operate a motor vehicle while listening to or wearing your headphones. Not only dangerous, it is illegal in many places.
7. NEVER operate heavy machinery while listening to or wearing your headphones.
8. We don’t recommend you use the headphones while riding a bicycle, running, or walking in heavy trafc areas. If you do, listen at a
lower volume so you can hear ambient noise.
The Occupational Safety Health Administration (OSHA) has issued headphone usage recommendations for maximum daily exposure
and sound pressure levels (measured in decibels (dB)). A decibel is a unit of measure of sound, and decibels increase exponentially as
sound gets louder. For example, conversational speech is typically around 60dB, and a rock concert in a stadium is often about 110dB.
