Precautions
On BlueTOOTh communication
ˎ BluETooTh wireless technology operates within a range of about 10 meters.
Maximum communication range may vary depending on obstacles (human
body, metal, wall, etc.) or electromagnetic environment.
ˎ The antenna is built into the unit as illustrated in the dotted line. The
sensitivity of the BluETooTh communication will improve by turning the
direction of the built-in antenna to the connected BluETooTh device. The
communication distance shortens when the obstacles are between the
antenna of the connected device and this unit.
Location of
built-in
antenna
ˎ The following conditions may affect the sensitivity of BluETooTh
communication.
ē There is an obstacle such as a human body, metal, or wall between this
unit and BluETooTh device.
ē A device using 2.4 Ghz frequency, such as a wireless lAN device, cordless
telephone, or microwave oven, is in use near this unit.
ˎ Because BluETooTh devices and wireless lAN (IEEE802.11b/g) use the same
frequency, microwave interference may occur and resulting in
communication speed deterioration, noise, or invalid connection if this unit
is used near a wireless lAN device. In such a case, perform the following.
ē use this unit at least 10 m away from the wireless lAN device.
ē If this unit is used within 10 m of a wireless lAN device, turn off the
wireless lAN device.
ē Install this unit and BluETooTh device as near to each other as possible.
ˎ 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:
ē where inflammable gas is present, in a hospital, train, airplane, or a petrol
station
ē near automatic doors or a fire alarm
ˎ 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.
ˎ We do not take any responsibility for the leakage of information during
BluETooTh communication.
ˎ Connection with all BluETooTh devices cannot be guaranteed.
ē A device featuring BluETooTh function is required to conform to the
BluETooTh standard specified by Bluetooth SIG, Inc. and be
authenticated.
ē 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.
ē While talking on the phone hands free, noise may occur, depending on the
device or communication environment.
ˎ Depending on the device to be connected, it may require some time to start
communication.
If you cannot operate the unit
ˎ Reset the unit.
Insert a small pin, etc., into the hole, and push it until you feel a click. Pairing
information is not deleted.
4-479-126-32(1)
ˎ If you are still unable to operate the unit even after the resetting operation
above, initialize the unit as follows.
Turn off the unit by pressing the PoWER button for more than 2 seconds.
GB
Then, press and hold the PoWER button and the
for about 7 seconds. The indicator (blue) flashes 4 times, and the unit is reset
to the factory settings. All pairing information is deleted.
CT
What is noise canceling?
ˎ The noise canceling circuit actually senses outside noise with built-in
KR
microphones and sends an equal-but-opposite canceling signal to the unit.
ē The noise canceling effect may not be pronounced in a very quiet
environment, or some noise may be heard.
ē The noise canceling effect may vary depending on how you wear the unit.
ē The noise canceling function works for noise in the low frequency band
primarily. Although noise is reduced, it is not canceled completely.
ē When you use the unit in a train or a car, noise may occur depending on
street conditions.
ē Mobile phones may cause interference and noise. Should this occur, locate
the unit further away from the mobile phone.
ē Do not cover the microphones of the headphones (MIC) with your hands.
The noise canceling function may not work properly.
On charging the unit
ˎ This unit can be charged using uSB only. Personal computer with uSB port is
required for charging.
ˎ This unit cannot be turned on, and the BluETooTh function and noise
canceling function cannot be used while charging.
Note on static electricity
ˎ Static electricity accumulated in the body may cause mild tingling in your
ears. To minimise the effect, wear clothes made from natural materials.
Others
ˎ Do not place this unit in a place exposed to humidity, dust, soot or steam,
subject to direct sunlight, or in a car waiting at a traffic signal. It may cause a
malfunction.
ˎ using the BluETooTh device may not function on mobile phones,
depending on radio wave conditions and location where the equipment is
being used.
ˎ If you experience discomfort after using the BluETooTh device, stop using
the BluETooTh device immediately. Should any problem persist, consult
your nearest Sony dealer.
ˎ listening with this unit at high volume may affect your hearing. For traffic
safety, do not use this unit while driving or cycling.
ˎ Do not put weight or pressure on this unit as it may cause the unit to deform
during long storage.
ˎ Do not subject the unit to excessive shock.
ˎ Clean the unit with a soft dry cloth.
ˎ Do not expose the unit to water. The unit is not waterproof.
Remember to follow the precautions below.
ē Be careful not to drop the unit into a sink or other container filled with
water.
ē Do not use the unit in humid locations or bad weather, such as in the rain
or snow.
ē Do not get the unit wet.
If you touch the unit with wet hands, or put the unit in a damp article of
clothing, the unit may get wet and this may cause a malfunction of the
unit.
ˎ The earpads may deteriorate due to longterm storage or use.
ˎ If you have any questions or problems concerning this unit that are not
covered in this manual, please consult your nearest Sony dealer.

預防措施
關於BLUETOOTH通訊
ˎ ˎ
BLUETOOTH無線技術可在約10 m的範圍內運作。
最大通訊範圍可能依障礙物（人體、金屬、牆面等）或電磁環境不同而定。
ˎ ˎ
天線內建在裝置中，如圖中虛線所示。將內建天線朝連接的BLUETOOTH裝置⽅向
轉動可以增加BLUETOOTH通訊的敏感度。當相連裝置的天線和本機之間存在障礙
物時，通訊距離將縮短。
內建天線
的位置
ˎ ˎ
以下情況可能會影響BLUETOOTH通訊的敏感度。
ē ˎ
本機和BLUETOOTH裝置間有人體、金屬或牆面等障礙物。
ē ˎ
無線區域網路裝置、無線電話或微波爐等2.4 GHz頻率的裝置正在本機附近使
用。
ˎ ˎ
因為BLUETOOTH裝置和無線區域網路（IEEE802.11b/g）使用相同的頻率，因此
如果本機在區域網路裝置的附近使用，則可能會發生微波干擾或造成通訊速度延
遲、雜訊或無效連
接。在此情況下，請執行以下步驟。
ē ˎ 請在距離無線區域網路裝置至少10 m的地⽅使用本機。
ē ˎ
若要在距離無線區域網路裝置10 m內的地⽅使用本機，請關閉無線區域網路
裝置。
ē ˎ
將本機和BLUETOOTH裝置安裝在盡量靠近彼此的地⽅。
ˎ ˎ
從BLUETOOTH裝置放射出的微波可能會影響電子醫療裝置的操作。在以下地點請
關閉本機和其他BLUETOOTH裝置，以免造成意外：
ē ˎ
有易燃性瓦斯的地點，如醫院、⽕車、飛機或加油站
ē ˎ
靠近自動門或⽕警警鈴的地⽅
ˎ ˎ
本機支援符合BLUETOOTH標準的安全功能，以便在使用BLUETOOTH無線技術時提供
安全的連接，但依設定不同而定，安全性可能會不足。使用BLUETOOTH無線技術
進行通訊時，請務必小心。
ˎ ˎ
對於BLUETOOTH通訊期間的資訊外洩，本公司不負有任何責任。
ˎ ˎ
不保證與所有BLUETOOTH裝置均能連接。
ē ˎ
有BLUETOOTH功能的裝置必須符合由Bluetooth SIG, Inc.指定的BLUETOOTH標
準並取得認證。
ē ˎ
即使連接的裝置符合上述的BLUETOOTH標準，依裝置功能或規格不同而定，部
分裝置仍可能無法正確連接或運作。
ē ˎ
使用手機的免持聽筒通話時，依裝置或通訊環境不同而定，可能會產生雜訊。
ˎ ˎ
依要連接的裝置不同而定，可能需要一些時間才能開始通訊。
如果您無法操作本機
ˎ ˎ
重設本機。
請在孔內插入一根小針等物後往下按壓，直到感覺有回彈。沒有刪除配對資訊。
ˎ ˎ
完成上述重設操作後，如果您還是無法操作本機，請依下列⽅式對本機進行初
始化。
按住POWER按鈕超過2秒以關閉本機。然後，按住POWER按鈕和
7秒。指示燈（藍色）將閃爍4次，此時本機將重設回出廠設定。所有配對資訊
皆被刪除。
什麼是防噪?
ˎ ˎ 防噪電路使用內建麥克風來感應外部噪音，並傳送相等但相反的防噪訊號至本機。
ē ˎ 在非常安靜的環境下，防噪效果可能不明顯，或是可能聽到一些噪音。
ē ˎ 防噪效果會因您配戴本機的⽅式而異。
ē ˎ 防噪功能主要針對處理低頻段的噪音。雖然可以降低噪音，但無法徹底消除。
ē ˎ 當您在⽕車或汽車內使用本機時，可能會因道路情況而出現一些噪音。
ē ˎ 行動電話可能會造成干擾並產生噪音。如果發生這種情況，請讓本機遠離行動
電話。
ē ˎ 請勿用手蓋住耳機的麥克風（MIC） 。這可能使防噪功能無法正常運作。
