Wireless Charging

<![if ! IE]>

<![endif]>ENGLISH

Align the bottom center of the charging case with the center of the wireless charger.

NOTE: The wireless charger is not provided. HBS-FN4 does not support wireless charging. The wireless charging function may not work in some wireless chargers. Wireless charging feature charges at a slower rate due to less power being transmitted to the charging case.

UVnano Description

UV-C LED process operates for ten minutes and begins when charging case (with earbuds) is plugged in.

UV-C LED does not operate while device is charging wirelessly such as on a pad or third party wireless charging device (this only applies to HBS-FN6).

-Independent testing shows the UVnano charging case kills 99.9% of bacteria (Staphylococcus aureus and Escherichia coli) on the speaker mesh of the earbuds in ten minutes while charging. The UV-C LED function works only when the charging case is connected to the power cable.

-For best result, it is recommended that the full 10 minutes of UV-C LED operation be performed while charging.

10

NOTE: The status indicator light blinks slowly during the UV-C LED operation.

The light will slowly illuminate on and off until the UV-C LED function is complete (10 minutes). Once completed, the indicator light will switch back to the always-on battery indicator,

see "Battery Status".

HBS-FN4 and HBS-FN5W models do not have a UV-C LED and mood light. Performance may vary based on usage conditions.

A white product may slightly differ in the color of the UV-C LED contact area, but there is no problem with the product performance.

UV-C LED does not operate while charging wirelessly.

CAUTION: Be aware that the temperature of the earbuds may rise while the UV-C LED is operating. Avoid direct eye and skin exposure to UV light.

Keep out of reach of children.

Additional Information

1.Radio frequency exposure

This Bluetooth LG Stereo Headset is a radio transmitter and receiver. When in operation it communicates with a Bluetooth-equipped mobile device by receiving and transmitting radio frequency

(RF) electromagnetic fields (microwaves) in the frequency range 2402 to 2480 MHz. YourBluetooth headset is designed to operate in compliance with the RF exposure guidelines and limits set by national authorities and international health agencies when used with any compatible LG Electronics mobile device.

2.Bluetooth Connection Precautions

The following environments affect the range and reception of Bluetooth signals:

--When walls, metal, human bodies, or other obstacles exist between the Bluetooth device and the connected device

14

--When equipment that uses 2.4 GHz frequency signals (Wireless LANs, wireless phones, microwave ovens, etc.) is placed near the devices being used

--When using a Bluetooth device (TV, laptop, etc.) other than the mobile phone, the sound quality may be affected by the specifications and performance of the device

3. Potentially explosive atmosphere	<![if ! IE]> <![endif]>ENGLISH
this is uncommon, your electronic device could generate sparks. Sparks in such areas could cause
Power off your electronic device when in any area with a potentially explosive atmosphere. Although
an explosion or fire resulting in bodily injury or even death. Areas with a potentially explosive
atmosphere are often, but not always, clearly marked.
4. Emergency calls
IMPORTANT!
This Bluetooth headset and the electronic device connected to the headset operate using radio
signals, mobile and landline networks as well as user-programmed functions, which cannot guarantee
connection under all conditions. Therefore you should never rely solely upon any electronic device for
essential communications (e.g. medical emergencies). Remember, in order to make or receive calls,
the headset and the electronic device connected to the headset must be powered on and in a service
area with adequate mobile signal strength. Emergency calls may not be possible on all mobile phone
networks or when certain network services and/or phone features are in use.
Check with your local service provider.
5. Battery information
A rechargeable battery has a long service life if treated properly. A new battery or one that has not
been used for a long period of time could have reduced capacity the first few times it is used.
Do not expose the battery to extreme temperatures, never above +50°C (+122°F) or below -10°C
(+14°F). For maximum battery capacity, use the battery at room temperature. If the battery is
used in low temperatures, the battery capacity will be reduced. The battery can only be charged in
temperatures between 0°C (+32°F) and +45°C (+113°F).

Important Safety Information

Avoiding hearing damage

Permanent hearing loss may occur if you use your headset at a high volume.

Set the volume to a safe level. Over time you can become accustomed to a higher volume that may sound normal but can be damaging to your hearing.

If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked.

The louder the volume, the less time is required before your hearing could be affected. Hearing experts suggest that to protect your hearing:

•Limit the amount of time you use the headset at high volume.

•Avoid increasing the volume to block out noisy surroundings.

• Decrease the volume if you can’t hear people speaking near you.

Using headsets safely

Use of headsets to listen to music while operating a vehicle is not recommended and is illegal in some areas. Be careful and attentive while driving. Stop using this device if you find it disruptive or distracting while operating any type of vehicle or performing any other activity that requires your full attention.
