Supplier’s Declaration of Conformity
Trade Name: SONY Model: YY2954
Responsible Party: Sony Electronics Inc.
Address: 16535 Via Esprillo, San Diego, CA 92127 U.S.A.
Telephone Number: 858-942-2230

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.

NOTE:
This unit 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 unit 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 unit does cause harmful interference to radio or television reception, which can be determined by turning the unit off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the unit and receiver.
Connect the unit 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.

This unit must not be co-located or operated in conjunction with any other antenna or transmitter.

This unit complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines. This unit has very low levels of RF energy that is deemed to comply without testing of specific absorption rate (SAR).

For customers in Canada
This unit contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject to the following two conditions:
(1) This unit may not cause interference; and
(2) This unit must accept any interference, including interference that may cause undesired operation of the unit.

The available scientific evidence does not show that any health problems are associated with using low power wireless devices. There is no proof, however, that these low power wireless devices are absolutely safe. Low power wireless devices emit low levels of radio frequency energy (RF) in the microwave range while being used. Whereas high levels of RF can produce health effects (by heating tissue), exposure of low-level RF that does not produce heating effects causes no known adverse health effects. Many studies of low-level RF exposures have not found any biological effects. Some studies have suggested that some biological effects might occur, but such findings have not been confirmed by additional research. The unit has been tested and found to comply with ISED radiation exposure limits set forth for an uncontrolled environment and meets RSS-102 of the ISED radio frequency (RF) Exposure rules.

High volume may adversely affect your hearing.
Do not use the unit while walking, driving, or cycling. Doing so may cause traffic accidents.
Do not use in hazardous areas unless the surrounding sound can be heard.

The unit is not waterproof. If water or foreign matter enters the unit, it may result in fire or electric shock. If water or foreign matter enters the unit, stop use immediately and consult your nearest Sony dealer. In particular, be careful in the following cases.

When using the unit near a sink or liquid container Be careful that the unit does not fall into a sink or container filled with water.
When using the unit in the rain or snow, or in humid locations
When using the unit while you are perspiring If you touch the unit with wet hands, or put the unit in the pocket of a damp article of clothing, the unit may get wet.

For details on the effects of contact with the human body from the mobile phone or other wireless devices connected to the unit, refer to the instruction manual of the wireless device.

Never insert the USB plug when the unit or charging cable is wet. If the USB plug is inserted while the unit or charging cable is wet, a short circuit may occur due to liquid (tap water, seawater, soft drink, etc.) or foreign matter on the unit or charging cable, and cause abnormal heat generation or malfunction.

This product (including accessories) has magnet(s) which may interfere with pacemakers, programmable shunt valves for hydrocephalus treatment, or other medical devices. Do not place this product close to persons who use such medical devices. Consult your doctor before using this product if you use any such medical device.

This product has magnets. Placing magnetic stripe cards in the vicinity of the product may affect the magnetism of the card and render it unusable.

Note about static electricity
If you use the unit when the air is dry, you may experience discomfort due to static electricity accumulated on your body. This is not a malfunction of the unit. You can reduce the effect by wearing clothes made of natural materials that do not easily generate static electricity.

Precautions

The two-dimensional code or the URL on the cover will help you access the help guide that describes useful notes or procedures in details.

On BLUETOOTH® communications

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: in hospitals, near priority seating in trains, locations where inflammable gas is present, near automatic doors, or near fire alarms.

Notes on wearing the unit

Because the headphones achieve a tight seal over the ears, forcibly pressing them against your ears or quickly pulling them off can result in eardrum damage. When wearing the headphones, the speaker diaphragm may produce a click sound. This is not a malfunction.

Other notes

When you use the unit as wired headphones, use the supplied headphone cable only. Make sure that the headphone cable is firmly inserted.
Do not apply weight or pressure to the unit for long periods, including when it is stored, as it may cause deformation.
If you experience discomfort while using the unit, stop using it immediately.
If you have any questions or problems concerning this unit that are not covered in this manual, please consult your nearest Sony dealer.
