Bluetooth Audio Transmitter for
iPod/iPhone
1. Introduction on
Bluetooth is a short-range wireless communication technology intended to replace the cables
connecting portable and/or fixed devices while maintaining high levels of security. It is designed to
communicate data/voice within short-range distance of 10m to 100m. Bluetooth technology has
achieved global acceptance such that any Bluetooth enabled device, almost everywhere in the world,
can connect to other Bluetooth enabled devices in proximity.
About Bluetooth Profile
Bluetooth Profile defines the way of communication between Bluetooth devices. The system of this
product supports the following Bluetooth Profiles.
A2DP
Advanced Audio Distribution Profile. It controls transmitting/receiving stereo audio
contents wirelessly.
AVRCP
Audio/Video Remote Control Profile. It remotely controls the functions of audio/video
devices such as pause, play, fast forward, rewind, and volume.
About Pairing
Pairing is a process of connecting two Bluetooth devices wirelessly. It creates a unique and encrypted
link between two Bluetooth devices and lets them communicate wirelessly and safely each other.
Bluetooth devices will not work if they have not been paired. Therefore, a user must make sure that
two Bluetooth devices are already paired before they use.
Cautions on iPod/iPhone
z If the iPod/iPhone does not play correctly, you may update your iPod/iPhone software to the
latest version. Please consult the Apple website, http://www.apple.com for more details.
z Sound distortion may occur when playing audio source with high recording levels. It is
recommended that you turn off the equalizer of the iPod/iPhone when distortion happens.
Please consult the iPod/iPhone instruction manual for more information including how to turn
off the equalizer.
z We are not responsible for any loss of or any damage to your iPod/iPhone that might result
from the use of this product.
Cautions on Bluetooth communication
z Bluetooth devices use 2.4 GHz band, which is the same as that used by wireless LAN devices
and microwave oven. Interference may occur near these devices and cause disconnectivity,
noise, or a degradation of communication speed.
z Although Bluetooth is theoretically and ideally supposed to be compatible to each other with
the same profiles and/or compatible profiles, connection with all Bluetooth devices cannot be
guaranteed since devices may differ in function, connectivity, display, interfaces, and
specifications by makers and developers.
z Some Bluetooth devices take more time to establish connection.

with supported A2DP, AVRCP profiles
3. If disconnection or lost link occurs, it maybe due to the following reasons.
- The range is over 10 meters between the two devices. (Please keep the distance within 10
meters.)
- Either device has been switched off. (Please make sure both devices are turned on.)
- RF (Radio Frequency) performance of your devices may have been affected by other
Bluetooth devices or other wireless devices with the same RF around them.
4. Please repeat Pairing Process in “5. How to use” section when wireless connection is unstable.
