Warning This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

2GB Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/

TV technician for help. You are cautioned that any changes or modifications not expressly approved in this manual could void your authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency

(RF) Exposure Guidelines. This equipment has very low levels of RF energy that it deemed to comply without maximum permissive exposure evaluation (MPE). But it is desirable that it should be installed and operated keeping the radiator at least 20 cm or more away from persons body (excluding extremities: hands, wrists, feet and ankles).

BLUETOOTH wireless technology is a short-

range wireless technology that enables wireless data communication between digital devices, such as a cellular phone and a headset. BLUETOOTH wireless technology operates within a range of about 10 m (33 ft). Connecting two devices is common, but some devices can be connected to multiple devices at the same time. You do not need to use a cable for connection since BLUETOOTH technology is a wireless technology, neither is it necessary for the devices to face one another, such is the case with infrared technology. For example, you can use such a device in a bag or pocket. BLUETOOTH technology is an international standard supported by millions of companies all over the world, and employed by various companies worldwide. On BLUETOOTH communication BLUETOOTH wireless technology operates within a range of about 10 m (33 ft). Maximum communication range may vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment. The following conditions may affect the sensitivity of BLUETOOTH communication. There is an obstacle such as a person, metal, or wall between this unit and BLUETOOTH device. A device using 2.4 GHz frequency, such as a wireless LAN device, cordless telephone, or microwave oven, is in use near this unit. 20GB Because BLUETOOTH devices and wireless LAN (IEEE802.11b/g) use the same frequency, microwave interference may occur and result in communication speed deterioration, noise, or invalid connection if this unit is used near a wireless LAN device. In such as case, perform the following. Use this unit at least 10 m (33 ft) away from the wireless LAN device. If this unit is used within 10 m (33 ft) of a wireless LAN device, turn off the wireless LAN device. Install this unit and BLUETOOTH device as near to each other as possible. Microwaves emitting from a BLUETOOTH device may affect the operation of electronic medical devices. Turn off this unit and other BLUETOOTH devices in the following locations, as it may cause an accident. where inflammable gas is present, in a hospital, train, airplane, or petrol station near automatic doors or a fire alarm This unit supports security capabilities that comply with the BLUETOOTH standard to provide a secure connection when the BLUETOOTH wireless technology is used, but security may not be enough depending on the setting. Be careful when communicating using BLUETOOTH wireless technology. We do not take any responsibility for the leakage of information during BLUETOOTH communication. Connection with all BLUETOOTH devices cannot be guaranteed. A device featuring BLUETOOTH function is required to conform to the BLUETOOTH standard specified by BLUETOOTH SIG, and be authenticated. Even if the connected device conforms to the above mentioned BLUETOOTH standard, some devices may not be DSX-A55BT 4-475-462-21(1) E:\DATA\4475462211\4475462211DSXA55BTE\01GB-DSXA55BTE\040CD.fm masterpage: Right 010COV.book Page 21 Thursday, August 22, 2013 4:17 PM connected or work correctly, depending on the features or specifications of the device. While talking on the phone hands free, noise may occur, depending on the device or communication environment. Depending on the device to be connected, it may require some time to start communication. Others Using the BLUETOOTH device may not function on cellular phones, depending on radio wave conditions and location where the equipment is being used. If you experience discomfort after using the BLUETOOTH device, stop using the BLUETOOTH device immediately. Should any problem persist, consult your nearest Sony dealer. If you have any questions or problems concerning your unit that are not covered in this manual, consult your nearest Sony dealer. Maintenance Replacing the lithium battery of the remote commander When the battery becomes weak, the range of the remote commander becomes shorter. Replace the battery with a new CR2025 lithium battery. Use of any other battery may present a risk of fire or explosion.

+ side up Notes on the lithium battery Keep the lithium battery out of the reach of children. Should the battery be swallowed, immediately consult a doctor. Wipe the battery with a dry cloth to assure a good contact. Be sure to observe the correct polarity when installing the battery. Do not hold the battery with metallic tweezers, otherwise a short-circuit may occur. WARNING Battery may explode if mistreated. Do not recharge, disassemble, or dispose of in fire. Cleaning the connectors The unit may not function properly if the connectors between the unit and the front panel are not clean. In order to prevent this, detach the front panel (page 7) and clean the connectors with a cotton swab. Do not apply too much force. Otherwise, the connectors may be damaged. 21GB DSX-A55BT 4-475-462-21(1) E:\DATA\4475462211\4475462211DSXA55BTE\01GB-DSXA55BTE\040CD.fm masterpage: Left 010COV.book Page 22 Thursday, August 22, 2013 4:17 PM Notes For safety, turn off the ignition before cleaning the connectors, and remove the key from the ignition switch.

While connected to a BLUETOOTH device, this unit cannot be detected from another device. Disconnect the current connection and search for this unit from another device. When the device pairing is made, set the BLUETOOTH signal output to on (page 9). Connection is not possible. The connection is controlled from one side

(this unit or BLUETOOTH device), but not both. Connect to this unit from a BLUETOOTH device or vice versa. The name of the detected device does not appear. Depending on the status of the other device, it may not be possible to obtain the name. No ringtone. Adjust the volume by rotating the control dial while receiving a call. Depending on the connecting device, the ringtone may not be sent properly. Set [RINGTONE] to [1] (page 19). The front speakers are not connected to the unit. Connect the front speakers to the unit. The ringtone is output only from the front speakers. The talkers voice cannot be heard. The front speakers are not connected to the unit. Connect the front speakers to the unit. The talkers voice is output only from the front speakers. A call partner says that the volume is too low or high. Adjust the volume accordingly using mic gain adjustment (page 16). Echo or noise occurs in phone call conversations. Lower the volume. Set EC/NC Mode to [EC/NC-1] or [EC/NC-2]

(page 16). If the ambient noise other than the phone call sound is loud, try reducing this noise. E.g.: If a window is open and road noise, etc., is loud, shut the window. If an air conditioner is loud, lower the air conditioner. 25GB DSX-A55BT 4-475-462-21(1) E:\DATA\4475462211\4475462211DSXA55BTE\01GB-DSXA55BTE\040CD.fm masterpage: Left 010COV.book Page 26 Thursday, August 22, 2013 4:17 PM The phone is not connected.
