 Audio and output
==================
The N900 has a microphone and stereo speakers located on each side of
the device. There is a 3.5 mm four-contact TRRS connector which
simultaneously provides stereo audio output and either microphone
input or video output. PAL and NTSC TV out is possible using a Nokia
Video Connectivity Cable (included upon purchase) or a standard TRRS
-&gt; 3x RCA cable.

There is a High-Speed USB 2.0 USB Micro-B connector provided for data
synchronization, mass storage mode (client) and battery charging. This
micro-USB connector was prone to failure. The Nokia N900, unlike
previous versions of Nokia's Internet Tablet, hasn't enabled support
for USB On-The-Go (the ability to act as a USB host) by default, this
in order to meet the deadlines for production and USB certification.
There is an ongoing community effort to add this support subsequently,
currently the software is in beta stage. Requiring a non-standard USB
cable or USB A-A adapter and software from the development repository.

The built-in Bluetooth v2.1 supports wireless earpieces and headphones
through the HSP profile. The Nokia N900 supports hardware capable of
stereo audio output with the A2DP profile. Built-in car hands-free
kits are also supported with the HFP profile.  File transfer is
supported (FTP) along with the OPP profile for sending/receiving
objects. It is possible to remote control the device with the AVRCP
profile. The DUN profile which permits access to the Internet from a
laptop by dialing up on a mobile phone wirelessly (tethering), the HID
profile which provides support for devices such as Bluetooth keyboards
and PAN profile for networking using Bluetooth are unsupported but can
be enabled.

The Bluetooth set also functions as an FM Receiver, allowing one to
listen to the FM radio. The N900 also has a 88.1-107.9 MHz FM
transmitter which can, for example, play music through a separate
radio. ( Note that the FM transmitter's frequency range can be
extended to 76.0-107.9 MHz by community supported modifications to the
operating system ) Furthermore, the Nokia N900 has Wi-Fi b/g
connectivity with support for WEP, WPA and WPA2 (AES/TKIP) security
protocols.

The Nokia N900 can synchronize with Microsoft Outlook through
ActiveSync and various other e-mail and calendar clients through
SyncML over bluetooth or the micro-USB. Contact information can also
be exchanged via the vCard file format which is supported commonly by
e-mail programs, including Evolution and Microsoft Outlook.

The device also features an infrared port (not compatible with IrDA)
that can be used to turn the Nokia N900 into a remote controller using
third-party software.
