Precautions

On BLUETOOTH® communications

• Bluetooth wireless technology operates

within a range of about 10 m (30feet).

Maximum communication range may vary

depending on obstacles (human body,

metal, wall, etc.) or electromagnetic

environment.

• Bluetooth communications may be

disabled, or noise or audio dropout may

occur under the following conditions.

– There is a human body between the unit

and the Bluetooth device.

This situation may be improved by

placing the Bluetooth device facing the

antenna of the unit.

– There is an obstacle, such as metal or a

wall, between the unit and the Bluetooth

device.

– A Wi-Fi device or microwave oven is in

use, or microwaves are emitted near the

unit.

– The antenna is built into the unit as

illustrated in the dotted line.

The sensitivity of the Bluetooth

communications will improve by

removing any obstacles between the

connected Bluetooth device and the

antenna of this unit.

• Because Bluetooth devices and Wi-Fi

(IEEE802.11b/g/n) use the same frequency

(2.4 GHz), microwave interference may

occur resulting in noise or audio dropout

or communications being disabled if this

unit is used near a Wi-Fi device. In such a

case, perform the following.

– Use this unit at least 10m (30feet) away

from the Wi-Fi device.

– If this unit is used within 10m (30feet)

of a Wi-Fi device, turn off the Wi-Fi

device.

– Install this unit and the 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, or a petrol station

– near automatic doors or a fire alarm.

• Due to the characteristic of the wireless

technology, the sound played on this unit

is delayed from the sound and music

played on the sending device. Therefore,

the image and sound may be misaligned

when viewing a movie or playing a game.

• This product emits radio waves when used

in wireless mode.

When used in wireless mode on an

airplane, follow flight crew directions

regarding permissible use of products in

wireless mode.

• 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

communications.

• 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, Inc.

and be authenticated.

– Even if the connected device conforms

to the above mentioned Bluetooth

standard, some devices may not be

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

communications.

If sound skips frequently during

playback

• The situation may be improved by

changing the wireless playback quality

settings or fixing the wireless playback

mode to SBC on the transmitting device.

For details, refer to the operating

instructions supplied with the transmitting

device.

• If you are using a smartphone, the

situation may be improved by shutting

down unnecessary applications or

rebooting the smartphone.

On the use of calling apps for

smartphones and computers

• This unit supports normal incoming calls

only. Calling apps for smartphones and

computers are not supported.

On charging the unit

• This unit can be charged using USB only.

Personal computer with USB port is

required for charging.

• This unit cannot be turned on, nor can the

Bluetooth function be used, during

charging.

• If you do not use the unit for a long time,

the rechargeable battery may not be able

to keep sufficient charge. The battery will

be able to keep a charge properly after

repeatedly discharging and charging

several times.

• If you store the unit for a long time, charge

the battery once every half year to prevent

over-discharge.

• If the length of time you can use the unit

became extremely short, the rechargeable

battery should be replaced with a new

one. Please contact your nearest Sony

dealer for a battery replacement.

Note on static electricity

• Static electricity accumulated in the body

may cause mild tingling in your ears. To

minimize the effect, wear clothes made

from natural materials.

If the unit does not operate properly

• Reset the unit.

When resetting this unit, charge the unit.

When charging starts, this unit is reset

automatically. The pairing information and

the other settings are retained.

• If the problem persists even after the

resetting operation above, initialize the

unit as follows.

Disconnect the micro-USB cable from the

micro-USB port, turn off the unit, then hold

down the



and – buttons simultaneously

for more than 7seconds. The indicator

(blue) flashes 4times, and the unit is reset

to the factory settings. All pairing

information is deleted.

• After the unit is initialized, it may not

connect to your iPhone or computer. In this

case, delete the pairing information of the

unit from the iPhone or computer, and

then pair them again.

On wearing the unit

• Because the headphones are of a high

density enclosure, forcing them against

your ears may result in eardrum damage.

Pressing the headphones against your

ears may produce a diaphragm click

sound. This is not a malfunction.

Others

• Do not place this unit in a place exposed to

humidity, dust, soot or steam, or in a car or

place subject to direct sunlight.

• Using the Bluetooth device may not

function on mobile phones, depending on

radio wave conditions and location where

the equipment is being used.

• High volume may affect your hearing.

• For traffic safety, do not use while driving

or cycling.

• Do not use the unit in places where it

would be dangerous if you are unable to

hear ambient sound, such as at railroad

crossings, train station platforms, and

construction sites.

• Do not put weight or pressure on this unit

as it may cause the unit to deform during

long storage.

• Do not subject the unit to excessive shock.

• Clean the unit with a soft dry cloth.

• Do not expose the unit to water. The unit is

not waterproof. Remember to follow the

precautions below.
