3. What your headphones can do

Your Jabra headphones let you do all this:

• Listen to music with or without the noise cancellation feature

• Enjoy a quiet environment thanks to the noise cancellation feature

How does Active Noise Cancellation work?

Active Noise Cancelling headphones are comprised of three parts: the microphone, which measures the ambient noise, the speaker, and between the two, the noise cancellation electronics which measures noise and generates the ‘anti-noise’ response.

Anti-noise is an inverted copy of the noise itself. When anti-noise is combined with the original sound disturbance it results in a lower level of noise perceived by our ears.

Speciﬁcations

• Frequency response: 20 Hz to 22 kHz • Weight: less than 200 grams

• Impedance: 64 Ohm • Power: 1 x AAA battery

• Noise Cancellation: up to 22dB • Battery life: up to 50 hours

• Dimensions: 174 x 163 x 80 mm

4. Getting started

The Jabra C820s is easy to operate with only one switch on the earcup to control the Active Noise Cancellation.

5. Inserting the battery

The battery door is located on top of the left ear cup. See ﬁg 2.

1. Open the battery door by pulling it up

2. Insert the AAA battery (positive end facing out)

3. Close the battery door

Note: The battery needs to be changed when the blue LED ﬂashes.

Caution, always use AAA non-rechargeable batteries. Dispose of used batteries according to the instructions.

6. Turning on the Active Noise Cancellation

1. Slide the headphone switch to the On position See ﬁg 3.

2. The blue LED should activate and the volume of low frequency background

noise should reduce noticeably

7. Connecting the headphones to your audio source

1. Connect the straight end of the detachablecable to your headphones.

See ﬁg 4.

2. Connect the other end to your audio source

3. Press Play on your audio source

You can enjoy the audio with or without the Active Noise Cancellation feature

8. Storing your headphones

1. Turn the headphones oﬀ

2. Rotate the earcups to fold the headphones ﬂat

3. Place the headphones and accessories in the carry case. See ﬁg 5.

9. Troubleshooting and FAQ

The noise cancellation is absent

3. 耳機的功能

您的 Jabra 耳機提供下列功能:

• 聽音樂,不論是否開啟噪音消除功能皆可使用

• 開啟噪音消除功能時,可享有安靜的收聽環境

主動式噪音消除功能如何運作? 主動式噪音消除型耳機由三個部分構成:測量環境噪音的麥克風、喇叭、及介於兩者之間測量噪音後產生「抗噪音」反應的噪音消除電子裝置。

「抗噪音」為噪音本身的逆向拷貝。抗噪音與原聲干擾結合時,耳朵感受的噪音程度就會降低。

規格

• 頻率響應範圍:20 Hz 至 22 kHz • 重量:不到 200g

• 阻抗:64 歐姆 • 電力使用:1 個 AAA 電池

• 噪音消除程度:最高可達 22 分貝 • 電池壽命:最長可達 50 小時

• 尺寸:174mm x 163mm x 80mm
