To select HDMI TV with eARC/ARC or HDMI TV without eARC/ARC function (Source):
Press INPUT button repeatedly on the sound bar or HDMI IN or ARC button on the remote control to select “HDMI
IN” or “TV ARC”.
Notes:
●This sound bar supports HDMI which enables eARC/ARC.
●To enable ARC make sure to use High Speed (category 2 with Ethernet) HDMI™ cable (with ARC).
●This eARC/ARC feature requires TV that supports eARC/ARC. Refer the operation manual of the TV to determine
which terminal supports eARC/ARC.
●To listen to the sound from a non-ARC-compatible TV, connect the audio output from TV to this system’s. (refer gure
above)
●This sound bar can be operated (power on/off or volume up/down) via a TV or similar component which supports
HDMI CEC (Consumer Electronics Control). If this does not work, it does not mean this system is faulty. Refer to the
operation manual of the respective component on how to activate the CEC.
Example: Go to the Menu of the component to search and enable the CEC. Different brands may have different naming
for the CEC.
For SHARP LCD TV, it is named as AQUOS LINK.
●The system will automatically power off if TV or similar component which supports HDMI CEC, is turned off.
●CEC is not available during Low power consumption mode (Eco mode on).
●To listen to the sound from this system, you will need to press button (refer page 15) or adjust the
speaker output settings within the TV menu. For details, refer to the operation manual of the TV.
●If you are unable to select external speaker setting from the TV menu (E.g. For SHARP LCD TV, it is named as
AQUOS AUDIO SP), turn the CEC OFF and ON again.
●To enjoy 3D images or 4K content, this system must be connected to a 3D or 4K-compatible TV and components
(3D BD player, etc.) via High Speed HDMI cables. Put on the 3D glasses (for 3D-compatibile TV and components),
otherwise 3D images or 4K content may not be viewed properly.

hassle of having to use cables to connect these devices.
This unit supports the following:
Communication System: Bluetooth Specication version 5.1
Bluetooth + Enhanced Data Rate (EDR).
Support Prole : A2DP (Advanced Audio Distribution Prole)
and AVRCP (Audio/Video Remote Control Prole)
Notes when using unit with a mobile phone
●This unit cannot be used to talk over the telephone even
when there is a Bluetooth connection made to a mobile
phone.
●Please refer to the operating manual supplied with the mo-
bile phone for details on operation of your mobile phone
