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.

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:

This device may not cause harmful interference, and
this device must accept any interference received, including interference that may cause undesired operation.

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:

This unit may not cause interference; and
This unit must accept any interference, including interference that may cause undesired operation of the unit.

This unit complies with FCC/ISED radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines and RSS-102 of the ISED radio frequency
(RF) Exposure rules. This unit should be installed and operated keeping the radiator at least 20 cm or more away from person’s body.
This conformity statement is only applicable to the YY7857E.

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 FCC/ISED radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines and RSS-102 of the ISED radio frequency (RF) Exposure rules.

This conformity statement is only applicable to the YY7860E.
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.

Inserting the USB plug or AC plug while it is wet may cause a short circuit due to foreign matter or liquid (tap water, seawater, soft drinks, etc.) getting on the main unit or charging cable.
This may cause malfunctions or abnormal overheating.

Never insert the USB plug or AC plug while the main unit or charging cable is wet.
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.

Precautions

On the power cord

The supplied AC power cord (mains lead) is designed exclusively for this unit. It should not be used in combination with any other devices.
Completely disconnect the AC power cord (mains lead) from the AC outlet (mains) if it is not going to be used for an extended period of time. When unplugging the AC power cord (mains lead), always grip the plug. Never pull the cord itself.

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
You can use the unit more comfortably and for a longer period of time by following the maintenance procedure below.

If the surface becomes dirty, wipe the surface using a soft, dry cloth or a cloth soaked in water or lukewarm water and wrung well. Depending on the type of dirt, it may not be possible to remove it.

Note

If the surface of the unit gets dirty, do not use detergent, thinner, benzine, alcohol, etc. to clean the unit.

Notes on batteries

Do not mix an old battery with a new one or mix different type of batteries.
When you are not going to use the unit for a long time, remove the batteries to avoid damage from battery leakage and corrosion.
Check if the batteries are inserted in the correct orientation (+ and -) when the wireless microphone does not turn on after battery replacement.
Batteries have a recommended use-by date for proper use. When using expired batteries, battery life will be extremely short. Check the use-by date on the batteries and if they are expired, replace them with new ones.

Other notes

If your skin remains in contact with the handle for a long time while the light is turned on, there is a risk of low-temperature burns. To carry a speaker while it is powered on, turn the light (lighting function) off.
Place the unit in a location with adequate ventilation to prevent heat buildup and prolong the life of the unit.
Do not splash water onto this product and the supplied accessories. Those are not waterproof.
Should any solid object or liquid fall into the unit, unplug the unit and have it checked by qualified personnel before operating it any further.
Water resistant performance is improved by the flat top structure of the unit, but this is not guaranteed for all the situations.
If you accidentally splash liquid on the unit, wipe it off with a dry cloth immediately.
The cap plays a very important role in maintenance of the water resistant performance. When using the unit, make sure that the cap is closed completely.
Put your fingertip directly onto the touch sensor for operations.
Do not operate the touch sensor with a wet hand to avoid a malfunction.
When the unit’s light seems bright or glaring, turn up the room lights or turn off the lighting function.
If sand or dust adheres to the caster wheels’ axles, or grass or lint gets wrapped around them, the caster wheels may malfunction.
If you have any questions or problems concerning this unit that are not covered in this manual, please consult your nearest Sony dealer.
