Parts Checklist
3. Avoid turning up the volume to block out noisy surroundings.
4. Turn the volume down if the sound from the headset or headphones prevents
you from hearing people speaking near you. See www.plantronics.com/

Exposure to Electromagnetic Energy in the Radio Frequency Band
When turned on, this device transmits and receives electromagnetic radiation in
the radio frequency (RF) bandwidth through its antenna. By international scientific
agreement, the unit of measurement of RF energy is the “specific absorption rate”,
or SAR. In the United States, the applicable SAR limit for the C900, set by the FCC
is 1.60 mW/g (millionths of watts per gram of mass), or 1.60 W/Kg (watts per
kilogram of mass). The maximum SAR exposure measured for the C900 was 0.738
W/Kg when the phone was turned on but not in use (body position), and 0.264 W/
Kg when the phone was in use (cheek position). In all cases, the phone was passed
by an independent testing facility.
Disposal and Recycling
Check and follow local laws regarding disposal and recycling of your phone.
