ESD PRECAUTIONS

Electrostatically Sensitive Devices (ESD)

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components

commonly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated

circuits and some field-effect transistors and semiconductor chip components. The following techniques should

be used to help reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off

any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a

commercially available discharging wrist strap device, which should be removed for potential shock reasons

prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive surface

such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ESD devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can

generate electrical charges sufficient to damage ESD devices.

5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESD

devices.

6. Do not remove a replacement ESD device from its protective package until immediately before you are

ready to install it. (Most replacement ESD devices are packaged with leads electrically shorted together by

conductive foam, aluminum foil or comparable conductive materials).

7. Immediately before removing the protective material from the leads of a replacement ESD device, touch the

protective material to the chassis or circuit assembly into which the device will by installed.

CAUTION : BE SURE NO POWER IS APPLIED TO THE CHASSIS OR CIRCUIT, AND OBSERVE ALL OTHER

SAFETY PRECAUTIONS.

8. Minimize bodily motions when handing unpackaged replacement ESD devices. (Otherwise harmless motion

such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate

static electricity sufficient to damage an ESD device).

CAUTION. GRAPHIC SYMBOLS

INTENDED TO ALERT THE SERVICE PERSONNEL TO THE PRESENCE OF UNINSULATED

“DANGEROUS VOLTAGE” THAT MAY BE OF SUFFICIENT MAGNITUDE TO CONSTITUTE A RISK OF

ELECTRIC SHOCK.

SERVICE PERSONNEL TO THE PRESENCE OF IMPORTANT SAFETY INFORMATION IN SERVICE

WIRELESS SUBWOOFER CONNECTION

LED indicator of wireless subwoofer

LED Color Status

Green

(Blink)

Attempting to make connection.

Green The connection is completed.

Red

The wireless subwoofer

is in standby mode

or the connection is failed.

Off

(No display)

The power cord of wireless

subwoofer is disconnected.

Setting up the wireless subwoofer

for the ﬁrst time

1. Connect the power cord to the subwoofer and plug

the power cord into a power outlet.

2. Turn on the main unit : The sound bar and wireless

subwoofer will be automatically connected.

- Green LED on the rear of wireless subwoofer

turns on.

Manually pairing wireless subwoofer

When your connection is not completed, you can

check red LED on the wireless subwoofer and the

wireless subwoofer does not make sound. To solve

the problem, follow the steps below.

1. Press Pairing button on the rear of the wireless

subwoofer.

- The green LED on the rear of the wireless

subwoofer blinks quickly.

2. Turn on the main unit.

3. Pairing is completed.

- The green LED on the rear of the wireless

subwoofer turns on.

Note

•It takes a few seconds (and may take longer) for the

main unit and the subwoofer to communicate with

each other and make sounds.

•The closer the main unit and the subwoofer, the

better sound quality. It is recommended to install the

main unit and the subwoofer as close as possible

and avoid the cases below.

- There is a obstacle between the main unit and the

subwoofer.

- There is a device using same frequency with this

wireless connection such as a medical equipment,

a microwave or a wireless LAN device.

- Keep the sound bar and the subwoofer away from

the device (ex. wireless router, microwave oven,

etc.) over 1m to prevent wireless interference.
