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

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

Yellow-green The connection is completed.
Red/Yellow green
(Blink alternately)

(No display)
Setting up the wireless subwoofer
for the fi rst time
1. Connect the power cord of the wireless subwoofer
to the outlet.
2. Turn on the main unit : The main unit and wireless
subwoofer will be automatically connected.
Attempting to make connection.
The wireless subwoofer
connection is initialized.
The power cord of wireless
subwoofer is disconnected.
- The LED of the wireless subwoofer lights up
alternately in red and yellow-green.
4. Disconnect the power cord of the main unit and the
wireless subwoofer.
5. Connect them again after the LED of the main unit
and the wireless subwoofer is fully turned off.
The main unit and the wireless subwoofer will be
paired automatically when you turn on the main unit.
- When the connection is completed, you can see
the yellow-green LED on the subwoofer.
Manually pairing wireless subwoofer
When your connection is not completed, you can see
the red LED or the blinking of yellow-green LED on
the wireless subwoofer and the subwoofer does not
make sound. To solve the problem, follow the below
steps.
1. Adjust volume level of the main unit to minimum by
pressing VOL - button repeatedly until stanby
LED on the main unit blinks slowly.
2. Press and hold (Mute) on the remote control for
about 3 seconds.
- The standby LED on the main unit blinks quickly.
3. If the LED of the wireless subwoofer already blinks
in yellow-green continually, you can skip this step.
Press and hold PAIRING on the back of the
wireless subwoofer for more than 5 seconds.
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.
