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
information, see www.nokia.com/support or your local Nokia website.
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
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
<10m

Introduction

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.

■Charge the battery
Before you can connect the headset to a Bluetooth device or use active
noise cancellation, you must charge the battery.
Before charging the battery, carefully read “Battery and charger
information”, p. 17.
1. Connect the charger to a wall outlet.
2. Connect the charger cable to the charger connector. The indicator
light for charging and active noise cancellation is red during
charging.
Charging the battery fully may take up to 2 hours.
3. When the battery is fully charged, the indicator light turns green.
Disconnect the charger from the headset, then from the wall outlet.
When you unplug a charger, hold and pull the plug, not the cord.
When the battery charge is low and Bluetooth connectivity is activated,
the headset beeps every 5 minutes and the indicator light for charging
and active noise cancellation flashes red.
Operating time when using Bluetooth connectivity
When active noise cancellation is activated, the fully charged battery
has power for up to 15 hours of talk time, up to 40 hours of standby
time, or up to 16 hours of music playing time.
When active noise cancellation is deactivated, the fully charged battery
has power for up to 24 hours of talk time, up to 600 hours of standby
time, or up to 25 hours of music playing time.

■Activate or deactivate Bluetooth connectivity
When Bluetooth connectivity is activated, you can connect the headset
to one or two compatible Bluetooth devices.
Even if Bluetooth connectivity is deactivated, you can use the headset
for handling calls and listening to music through the supplied audio
cables.
Activate
To activate Bluetooth connectivity, press and hold the multifunction key
for about 2 seconds. The headset beeps, and the Bluetooth indicator
light briefly flashes green.
The headset tries to connect to the last used mobile device that supports
the HFP Bluetooth profile and the last used music player that supports
the A2DP profile, if the same device does not support both profiles.
When the headset is connected to the device and is ready for use, the
Bluetooth indicator light flashes blue slowly.
If the headset has not been previously paired with any device, it
automatically enters pairing mode. See also “Pair and connect the
headset to a Bluetooth device”, p. 10.
Deactivate
To deactivate Bluetooth connectivity, press and hold the multifunction
key for about 5 seconds. The headset beeps, and the Bluetooth indicator
light briefly flashes red.
If the headset is not connected to a Bluetooth device within about 30
minutes, the headset deactivates Bluetooth connectivity automatically.
Bluetooth connectivity is also deactivated if you connect the CA-143U
or CA-182U audio cable to the headset.

■Pair and connect the headset to a Bluetooth
device
If your mobile device supports the A2DP Bluetooth profile and has a
music player feature, you can use the device to also play music through
the headset.
If your mobile device does not support the A2DP profile, you can
separately pair the headset with the mobile device and a music player
that supports this profile. If you have paired and connected the headset
with your mobile device, disconnect the headset from it before pairing
the headset with the music player.
1. Ensure that your mobile device or music player is switched on.
2. To pair the headset if it has not been previously paired with a device,
activate Bluetooth connectivity on the headset. The headset enters
pairing mode, and the Bluetooth indicator light starts to flash blue
quickly.
To pair the headset if it has been previously paired with a device,
ensure that Bluetooth connectivity is deactivated on the headset,
and press and hold the multifunction key (for about 5 seconds) until
the blue indicator light starts to flash quickly.
3. Within about 3 minutes, activate Bluetooth connectivity on your
mobile device or music player, and set it to search for Bluetooth
devices. For instructions, see the user guide of your device .
4. Select the headset from the list of found devices on your mobile
device or music player.
5. If necessary, enter the passcode 0000 to pair and connect the
headset to your device. If your device does not have a keypad, it may
use this passcode by default.
In some devices, you may need to make the connection separately
after pairing. You only need to pair the headset with your device
once.
If pairing is successful, the headset appears in the menu of your device
where you can view the currently paired Bluetooth devices.
