Important tips
N91 and N91 8GB common
Nokia PC Suite (especially Nokia Audio
Manager)
Nokia PC Suite is optimized for management of data on
Phone memory [C:]. Nokia PC Suite is recommended for
managing contacts, calendar and notes. To manage
content on hard drive [E:] (Music, Images, Movies, Appli-
cations etc) it is recommended to use Mass storage and/
or Media player (for Music) mode.
Note that when using Nokia PC Suite it is recommended
to not run applications (Gallery, etc) during the PC Suite
session.
Nokia PC Suite runs in the background on your PC and
sometimes when using Mass storage or Media player
mode a pop up comes up saying PC suite - N91
connected in non compatible mode please change from
UI. This message only applies when using PC Suite mode.
For optimal performance it is recommended to use the
latest version of PC suite available from
www.nokia-asia.com/pcsuite or other local regional sites.
File Management
The N91 and N91 8GB, like many other computers, uses
FAT32 (32-bit File Allocation Table) to handle files and
folders in the hard disk. Like a computer, folders and the
number of files within each folder needs to be managed
for optimal performance.
Windows Media player by default typically divides songs
up into folders by artist, album etc however when using
other sync/transfer methods (eg. Mass storage mode) it is
recommended to limit the number of files in each folder.
For optimal performance when managing content on hard
drive [E:], it is recommended to limit the number of files
or folders within a single folder/directory to contain not
more than 50 files/folders of content (Images, Music,
Videos etc). Many gigabytes of content can be handled
more efficiently when managed by using sub folders. In
most cases compatible Windows Media player manages
your music files in the same manner automatically.

missing
• When using PC Suite mode, view the correct window
in PC Suite for content transfer progress. Using PC
Suite mode to sync/transfer content sometimes
appears that the transfer is completed. The data has
not transferred yet from the PC to the device.
• Reset the device to factory settings (see ‘Reset factory
settings back to default settings’).
• Update the software to the latest version available.
HDD User Guide

to update device software (i.e. when and how to use PC
Suite including Nokia Audio Manager and when and how
to use other Mass storage or Media player modes).
NOTE:
Digital rights management technologies may prevent
some backup data from being restored. WMDRM
protected content activation keys may be lost during
back-up and restore. Losing the activation keys may
limit your ability to use the same content on your
device again. Contact your service provider for more
information about the DRM used for your content.
Synchronizing Windows Media DRM
protected songs
To ensure content activation keys for WMDRM are
transferred with the songs use Media player mode to
synchronize to the device or PC.
Connectivity

methods of connectivity. Like computers, your device may
be exposed to viruses, malicious messages and
applications, and other harmful content. Exercise caution
and open messages, accept connectivity requests,
download content, and accept installations only from
trustworthy sources. To increase the security of your

devices (including a compatible PC), consider installing
antivirus software with a regular update service and using
a firewall application.
Reset the Device settings back to
factory default (memory/data)
Sometimes the performance of the device may appear
slower (i.e. opening applications).
When the device reaches this state, it is recommended to
reset the device. Before a reset, back up the data on the
devices’ phone and hard drive memory. The same proce-
dure applies as when preparing for a software update.
NOTE:
Digital rights management technologies may prevent
some backup data from being restored. WMDRM
protected content activation keys may be lost during
back-up and restore. Losing the activation keys may
limit your ability to use the same content on your
device again. Contact your service provider for more
information about the DRM used for your content.

Bluetooth accessory tips
• Non-DRM formats such as MP3 provide the best audio
with Bluetooth stereo headsets. When listening to
DRM protected content using Bluetooth stereo head-
sets it is recommended to wait until the DRM content
is finished playing before accessing other functions or
applications of the device such as email, Gallery,
visualizations.
• To maintain headset connection with the device it is
recommended to charge the headset periodically and
to stay within range.
• Sometimes there may be mono audio vs stereo audio
after reconnection, unpair and reset headset, then
reconnect via the Options menu.
• Some headsets may disconnect when the charger is
plugged in while the headset is connected.
• When switching from BT Stereo to voice call, some
headsets send the mono audio to both L and R ear
while some only play mono audio to one ear.
• In some headsets the volume control only adjusts the
volume of the headset, when connected to the device,
where the audio volume setting of the device remains
the same as it was before the headset was connected.
• Sometimes breaks in audio playback may occur when
using other device functions while listening to music
(i.e. SMS, web etc.)
• Sometimes headsets automatically connect and
sometimes they may need to be connected manually
via the options menu.
Gallery
The Gallery on N91-8GB allows a user to view selected
photos, images, and videos. The Gallery also enables
selected media files (including music) to be shared and
streamed using UPnP. Overall Music management is done
using the Music Player while general file management is
done using the included File Manager.
Gallery looks for content in hard drive memory [E:]
\Images, \Video clips and \Gallery folders (and sub folders).
All media in other directories will not be visible in the
Gallery unless moved/copied to \Images, \Video clips or
\Gallery. However it is recommended to keep the total
number of files in Gallery below 300. When choosing con-
tent to be removed from Gallery, files should be removed
from these directories.
Gallery allows a user to view images by using the All Files
or the Images and Video features. The Images and Video
features provide a thumbnail gallery of a users image
collection, The performance of this feature depends on the

nature and size of a users image collection. When using
the Images and Video feature to view a recent photo(s)
note that it may take some time to render the thumbnails
of the most recent photos as it builds the thumbnail
gallery.
