USE ONLY DOMESTIC AC OUTLETS
Connecting the unit to an outlet supplying a higher voltage may create a fire hazard.

HANDLE THE POWER CORD WITH CARE
Do not disconnect the plug from the AC outlet by pulling the cord; always pull the plug itself. Pulling
the cord may damage it. If you do not intend to use your unit for any considerable length of time,
unplug the unit. Do not place furniture or other heavy objects on the cord, and try to avoid dropping
heavy objects on it. Do not tie a knot in the power cord. Not only could the cord be damaged, but a
short circuit could also be caused with a consequent fire hazard.

PACKAGING
Save all packing material. It is essential for shipping in the event the unit ever needs repair.
IF ORIGINAL PACKAGING IS NOT USED TO RETURN THE UNIT TO THE SERVICE CENTRE, DAMAGE IN
TRANSIT WILL NOT BE COVERED BY WARRANTY.
WATTS
The most consistent standards for measuring watts are “Program Power” and “RMS” because these
measure average sustained levels.
Where loudspeakers have integrated amplifiers, then load (resistance, measured in ohms) is known so
the wattage rating is fixed.

Command Structure:
Each command starts with a # sign (ASCII 0x23) followed by a 3-character command code.
If there are any parameters for thecommand, the parameters are given intext format,separated by a
space (ASCII 0x20) from the command code.
The # character must never appear in the parameters.
A carriage return (ASCII 0x0d) indicates the end of the command.
A line feed (ASCII 0x0a) canoptionally follow the carriage return and will be ignored.
Each command generally may not exceed 20 bytes including the start of command and end of
command bytes.
The illustration of the command structure is as follows:
<Command> = <Start of Command><Command Code>[<sp><Parameters>]<End of Command>
<Start of Command> = #, ASCII 0x23
<Command Code> = <byte><byte><byte>
<sp> = space, ASCII 0x20
<Parameters> = command-specific
<End of Command> = CR, ASCII 0x0d LF, ASCII 0x0a

Response Structure:
Upon receiving a command the soundbar will execute the command and send back a response.
•The response starts with an “@” sign (ASCII 0x23), followed by the original command code and a
space (ASCII 0x20), and a result code, either “OK” or “ER”.
•If there are any parameters or additional messages, the parameters or messages are given in text
format, separated by a space (ASCII 0x20) from the result code.
•The “@” character (ASCII 0x40) must never appear in the parameters or message.
•A carriage return (ASCII 0x0d) indicates the end of response. Each response generally may not exceed
25 bytes including the start of response and the end of response bytes.
•The illustration of the response structure is as follows.
<Response> = <Start of Response><Command Code><sp><Result Code> [<sp><Parameters>]<End of
Response>
<Start of Response> = @, ASCII 0x40
<Command Code> = <byte><byte><byte>
<Result Code> = OK|ER
<sp> = space, ASCII 0x20
<Parameters> = command-specific
<End of Response> = CR, ASCII 0x0d

Status Update Messages Structure:
If the verbose mode is set to 2 or 3, the soundbar will send status update messages automatically.
These messages are not a response to any particular command. Any status change caused by
commands from RS232 control, front panel buttons, IR remote control, or playback progress may
trigger status update messages.
The status update messages have the following structure:
<Update> = <Start of Update><Status Code>[<sp><Parameters>]<End of Update>
<Start of Update> = @, ASCII 0x40
<Status Code> = <byte><byte><byte>
<sp> = space, ASCII 0x20
<Parameters> = status-specific
<End of Response> = CR, ASCII 0x0d
Command Sequence:
Commands are executed in the order they are received. The control client should wait for a response
from the soundbar before sending the next command.
If the soundbar receives a new command before executing the previous command, the soundbar may
execute the commands in sequence or discard the previous command, depending on the internal
processing of the soundbar. The control client should avoid sending multiple commands in sequence
without waiting for a response.
If the host does not receive a response from the soundbar 10 seconds after the command is issued,
the host may consider the command or response lost during transmission, and can retransmit the
command.

A. Remote Control Commands
Commands that are mapped to a remote control buttons
No parameters are needed for these commands. The soundbar handles the commands as if it
receives the same IR remote commands.
