BH870 Wireless Bluetooth® Headset User’s Guide 31
Q I hear a low noise in the headset when there is silence at the other end?
A Your headset is probably using one of the highest volume settings. Decrease the speaker volume on the headset by sliding your
finger down the touch-sensitive panel on the side of the headset.
Q I can’t hear sound or listen to music from my PC in my headset.
A Please check the following:
- Make sure the USB Bluetooth Adapter is selected as the current audio device both in the Windows sound control panel and in the
application you are using.
- Make sure the audio link to the PC is open (e.g., by right-clicking on the Jabra Device Service icon in the Windows notification area
on your PC).
- Make sure softphone is enabled in the Jabra PC Suite.
Q Does Wi-Fi interfere with the BH870 Headset if I have them in the same place?
A No, the BH870 Headset uses adaptive frequency hopping, thereby avoiding channels that are blocked by Wi-Fi. To ensure good
sound quality, only the free channels are used.
Q Is it possible to listen in on calls with the headset?
A The risk of unauthorized access to communication via a Bluetooth headset is very limited. The headset uses 128-bit encryption.
Q What is the range of the headset?
A The headset supports the following maximum ranges:
- 100m when talking through the USB Bluetooth Adapter (softphone)*
- 25m when talking on (most) mobile phones**
In practice you may find the range to be somewhat shorter due to physical obstructions and electromagnetic interference. Also, if
your headset is in power save mode, the range is slightly reduced. The sound in your headset will slowly deteriorate as you move
farther from the softphone or mobile phone. Move back into range and sound quality is restored. If you move all the way out of
range while talking, you will lose all sound.
Q What is the talk time of the headset?
A Up to 6 hours. Talk time depends on the device with which the headset is connected.
* Range varies according to the environment in which the headset is used.
** Range depends on the device with which the headset is connected.
