Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include fueling areas such as
gasoline or petrol stations; below deck on boats; fuel or chemical transfer or storage facilities; vehicles using liquefied
petroleum gas (such as propane or butane); areas where the air contains chemicals or particles, such as grain, dust, or metal
powders; and any other area where you would normally be advised to turn off your vehicle engine.
Blasting areas: To avoid interfering with blasting operations, turn off Bluetooth technology on the headset when in a “blasting
area” or in areas that post “Turn off two-way radio”. Obey all signs and instructions.
US Information Concerning the Federal Communications Commission ("FCC") Requirements for Hearing Aid Compatibility with Wireless Devices
When wireless devices are used near hearing devices (such as hearing aids and cochlear implants), users may detect a buzzing,
humming, or whining noise. Some hearing devices are more immune than others to this interference, and wireless devices also
vary in the amount of interference that they generate.
The wireless telephone industry has developed ratings to assist hearing device users in finding wireless devices that may be
compatible with their hearing devices. Not all wireless devices have been rated. Wireless devices that are rated will have the
rating displayed on the box together with other relevant approval markings.
The ratings are not guarantees. Results will vary depending on the user's hearing device and hearing loss. If your hearing device
is vulnerable to interference, you may not be able to use a rated wireless device successfully.
Consulting with your hearing health professional and testing the wireless device with your hearing device is the best way to
evaluate it for your personal needs.
