Bluetooth is a wireless protocol for exchanging data over short distances from fixed and mobile devices.

Bluetooth technology allows mobile phones, computers, Personal Digital Assistants (PDA's), printers, and speakers to be easily connected to one another without wires.

Bluetooth technology can handle both data and voice transmissions at the same time. For instance, you could enjoy a hands-free chat on your mobile phone while sending a document wirelessly to a Bluetooth enabled printer or fax machine.

Bluetooth communicates on a frequency of 2.45 gigahertz, which has been dedicated by international agreement for use by industrial, scientific and medical devices (ISM) only. A number of devices that you may already use take advantage of this same radio-frequency band such as, baby monitors, garage-door openers and cordless phones.

A profile is a complete definition of how a product manufacturer can implement Bluetooth wireless technology in a particular usage case. To put it simply, profiles are the "services" offered by a devices. For two devices to connect to complete a user task, both devices must implement a common profile.

The pairing process is used to establish a link between devices and, in most cases, will allow devices to automatically "remember" one another during subsequent uses. All Bluetooth devices must go through a pairing process to establish a connection before their first use. The paring process can take between ten seconds and several minutes, depending on the device. Miccus products include LED indicator lights that signal the user when successful pairing has occurred.

A class 1 Bluetooth wireless device has a transmission range of 328 feet (100 meters) within a line of sight, but will vary depending on the surrounding conditions. A class 2 Bluetooth device has a range of approximately 33 feet (10 meters) and a class 3 has a range of about 10 feet (3 meters). Communication range may differ for the following reasons: walls or other obstacles are located between the devices, Radio Frequency (RF) interference is present, environmental conditions, and the type of software being used, if applicable.

Yes. Bluetooth manufacturers are required to make their Bluetooth products compatible with all other Bluetooth devices; else the products are not allowed to display the Bluetooth logo.

Pairing is required only when connecting two devices for the first time, as the devices should recognize each other automatically during subsequent connections.

You will have to complete the pairing process again if the pairing information is deleted or corrupted. This can happen under the following circumstances:

• Pairing information is deleted after device maintenance
• The unit is paired with nine or more devices

If a device you have already paired cannot be connected, pair the device again.

A passcode (sometimes called a passkey or pairing code) is a number that associates one Bluetooth enabled device with another. For security reasons, most Bluetooth enabled devices require you to use a passcode.

Note: Miccus accessories use the default passcode "0000".

The sound may skip or the playback speed may change if a device that generates electromagnetic radiation is nearby. Wireless LANs, microwave ovens and other Bluetooth devices are some examples of devices that generate electromagnetic radiation. Move away from any sources that may be interfering with the communication of your devices.

There are several factors that could be leading to a dropped Bluetooth connection:

• Ensure that you are wearing or positioning the accessory in the appropriate way. If the current location continues to result in a dropped connection, try changing the position of the device. Check your user guide for complete details on proper positioning.
• If you have the device in your pocket or bag, an alternative mode of transportation is to use a carry case or arm band to prevent dropped connections.
• Ensure that the transmitter and receiver are fully charged. Poor battery life on either could impact performance and cause a dropped connection.
• If you are using the device indoors, other wireless equipment, such as wireless internet, cordless phones or monitors that operate on the 2.45 GHZ frequency may cause interference and contribute to a dropped connection.
• If you are using the device outdoors, the Bluetooth signal may be affected by environmental conditions.
• Keep metal objects, such as keys or coins, away from the device and accessory to avoid interference.

If none of the above corrects the issue, attempt to delete the current Bluetooth partnership and reconnect the Bluetooth accessory. Please see your manufacturer's instruction manual for how to delete the existing Bluetooth partnership.
