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
Model, Modèle: YY7866E
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.

Supplier's Declaration of Conformity
Trade Name: SONY
Model: YY7866E
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.
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.
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.
This product 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.
Never insert the USB plug when the main unit or charging cable is wet. If the USB plug is inserted while
the main 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 main unit or charging cable, and cause abnormal heat generation
or malfunction.

Notes on waterproof and dustproof features
(Read before using the unit)
The supplied accessories are neither waterproof nor dustproof.
On waterproof and dustproof performance of the unit
The unit, with the cap fastened securely, has a waterproof specification of IPX7 as specified in "Degree
of protection against water immersion" of the IEC60529 "Ingress Protection Rating (IP Code)", and a
dustproof specification of IP6X as specified in "Degrees of protection against solid foreign objects".
• The supplied accessories and the connectors of this unit (USB) are neither waterproof nor dustproof.
To reduce the risk of fires or electric shocks, do not expose the unit to water or droplets while using
any connectors (USB) .
Note that malfunctions as a result of water immersion or dust intrusion caused by misuse by the
customer are not covered by the warranty.
To maintain waterproof and dustproof performance
Carefully note the precautions below to ensure proper use of the unit.
• The unit passes the drop test from 1.22 m (4.0 ft) on plywood of 5 cm (1.97 in) thickness conforming to
MIL-STD810H Method 516.8-Shock. However, this does not guarantee no damage, no breakdown, or
waterproof and dustproof performance in all conditions. Deformation or damage from dropping the
unit or subjecting it to mechanical shock may cause deterioration of the waterproof and dustproof
performance.
• Do not pour high-temperature water or blow hot air from a hair dryer or any other appliance on the
unit directly. Also never use the unit in a place subject to high temperatures, such as in a sauna or
near a heat source.
CAUTION : Handle the cap (-) with care. The cap plays a very important role in maintenance
of the waterproof and dustproof performance. When using the unit, make sure that the cap is
closed completely. When closing the cap, be careful not to allow foreign objects inside. If the cap is not
closed completely the waterproof and dustproof performance may deteriorate and may cause a
malfunction of the unit as a result of water or dust particles entering the unit.
Precautions
On placement
• To eliminate the risk of malfunctions, avoid the following locations when placing or leaving this unit.
– A place subject to high temperatures, such as under direct sunlight or lighting equipment, near a
heat source, or in a sauna
– Inside a vehicle with the windows closed (especially in summertime)
– A place exposed to hot air, such as from a hair dryer
• Place this unit on a flat, level surface. When placed on a sloped surface, the unit may fall over or
fall off the surface due to its own vibration, resulting in injuries, malfunctions, or performance
degradation.
• This unit is not anti-magnetic. Keep objects susceptible to magnetism (recorded tapes, watches, cash
cards and credit cards with magnetic coding, etc.) away from the unit. When you carry around the
unit, keep this in mind as well.
How to care for the unit
Although the fabric part of the unit has water repellent treatment applied, you can use the unit more
comfortably and for a longer period of time by following the maintenance procedure below.
• If the surface of the unit gets dirty in the following cases, wash the unit with fresh water (tap water,
etc.) promptly to remove the dirt. Leaving dirt on its surface may cause the fabric part or the passive
radiator section (-) to discolor or deteriorate, or the unit to malfunction.
Ex.
– When salt, sand, etc. is stuck on the unit after using it on a beach, pool side, etc.
– When the unit is stained with sweat or foreign substances (sunscreen, suntan oil, etc.)
Note
• If the surface of the unit gets dirty, do not use detergent, thinner, benzine, alcohol, etc. to clean the
unit because it will affect the water repellent function of the fabric part of the unit.
• If sand grains, etc. enter the fabric or other part of the unit, remove them carefully. Never use a
vacuum cleaner, etc. on the unit. It may cause damage of the speaker section or other part of the unit.
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.
Other notes
• When placed in an extremely hot or cold environment, the unit stops battery charging for safety
reasons. When the battery is kept charging itself for an extended period of time, the unit may stop
battery charging as well. In such a case, make sure that the ambient temperature is within the battery
charging temperature range (5 °C - 35 °C (41 °F - 95 °F)), unplug and plug the USB cable, and then
charge the battery all over again.
• Even if you do not intend to use the unit for a long time, charge the battery to its full capacity once
every 6 months to maintain its performance.
• If you have any questions or problems concerning this unit that are not covered in this manual, please
consult your nearest Sony dealer.
