1. Introduction  
The Nokia Bluetooth Stereo Headset BH-905i with active noise  
cancellation allows you to handle calls hands-free with a compatible  
mobile device and listen to music from a compatible music player.  
Active noise cancellation helps you to use the headset also in noisy  
environments.  
You can connect the headset to a compatible device using Bluetooth  
wireless technology or the supplied audio cables.  
Read this user guide carefully before using the headset. Also, read the  
user guide for the device that you connect to the headset. For more  
This product may contain small parts. Keep them out of the reach of  
small children.  
Note: The surface of this device does not contain nickel in the  
platings. The surface of this device contains stainless steel.  
Bluetooth wireless technology  
Bluetooth wireless technology allows  
you to connect compatible devices  
without cables. The headset and the  
<10m  
other device do not need to be in line  
of sight, but they should be within 10  
metres (33 feet) of each other. The  
closer the headset and the other  
device are to each other, the better  
the performance. The optimal  
operating range is shown in dark grey  
in the picture. The connection is  
subject to interference from distance and obstructions (shown in light  
grey) or other electronic devices.  
The headset is compliant with the Bluetooth Specification 2.1 + EDR  
supporting the following profiles: Headset Profile 1.1, Hands-Free  
4
 
   
I n t r o d u c t i o n  
Profile (HFP) 1.5, Advanced Audio Distribution Profile (A2DP) 1.2, and  
Audio Video Remote Control Profile 1.0. Check with the manufacturers  
of other devices to determine their compatibility with this device.  
About active noise cancellation  
Wolfson AudioPlusTM Ambient Noise Cancellation technology uses  
patented signal processing technology and advanced acoustic design  
expertise to deliver class-leading active noise cancellation for stereo  
headsets and headphones.  
This novel feed-forward technology cancels more decibels of noise  
across a wider frequency range than traditional feedback technologies,  
providing a peaceful and tranquil environment for users wherever they  
happen to be. As Wolfson's advanced technology does not process the  
playback audio stream, your music comes through in untouched hi-fi  
quality stereo.

4. Battery and charger information  
This device has an internal, nonremovable, rechargeable battery. Do not attempt  
to remove the battery from the device as you may damage the device. This device  
is intended for use when supplied with power from the following chargers: AC-3,  
AC-4, AC-5, AC-15, and DC-4. The exact charger model number may vary  
depending on the type of plug. The plug variant is identified by one of the  
following: E, X, AR, U, A, C, K, or B. The battery can be charged and discharged  
hundreds of times, but it will eventually wear out.  
Operating times are estimates only. Actual times are affected by, for example,  
device settings, features being used, battery condition, and temperature.  
If the battery has not been used for a long time, to begin charging, you may need  
to connect the charger, then disconnect and reconnect it.  
If the battery is completely discharged, it may take several minutes before the  
charging indicator is displayed.  
When your charger is not in use, unplug it from the electrical plug and the device.  
Do not leave a fully charged battery connected to a charger, as overcharging may  
shorten the battery's lifetime. If left unused, a fully charged battery will lose its  
charge over time.  
Always keep the battery between 15°C and 25°C (59°F and 77°F). Extreme  
temperatures reduce the capacity and lifetime of the battery. A device with a hot  
or cold battery may not work temporarily.  
Do not dispose of batteries in a fire as they may explode. Dispose of batteries  
according to local regulations. Recycle when possible. Do not dispose as  
household waste.  
Use the charger for its intended purpose only. Improper use or use of unapproved  
chargers may present a risk of fire, explosion, or other hazard, and may invalidate  
any approval or warranty. If you believe the charger is damaged, take it to a  
service centre for inspection before continuing to use it. Never use a damaged  
charger. Only use the charger indoors.  
17  
 
 
T a k e c a r e o f y o u r d e v i c e  
Take care of your device
