Bush 9511143, Instruction Manual

For further information on using this feature refer to the 
instructions of the application you use.

Note: 

Depending on model, your TV may not support this 

function. The application may not be compatible with all 
mobile devices. Both of the devices must be connected 
to the same network. This feature is only functional on 
TV source.

CEC

This function allows the user to control the CEC-enabled 
devices, that are connected through HDMI ports by using 
the remote control of the TV.
The 

CEC

 option in the

 Settings>System>Device Settings 

menu should be set as 

Enabled

 at first. Press the 

Source

button and select the HDMI input of the connected CEC 
device from the 

Sources List

 menu. When a new CEC 

source device is connected, it will be listed in 

Sources

menu with its own name instead of the connected HDMI 
port’s name (such as DVD Player, Recorder 1, etc.).
The TV remote is automatically able to perform the main 
functions after the connected HDMI source has been 
selected. To terminate this operation and control the TV 
via the remote again, press and hold the “0-Zero” button 
on the remote control for 3 seconds.
You can disable the CEC functionality by setting the 
related option under the

 Settings>System>Device 

Settings

 menu accordingly.

The TV supports ARC (Audio Return Channel). This feature 
is an audio link meant to replace other cables between the 
TV and an audio system (A/V receiver or speaker system).
When ARC is active, the TV will mute its other audio 
outputs, except the headphone jack, automatically and 
volume control buttons are directed to the connected 
audio device. To activate ARC set the 

Sound Output 

option in the

 Settings>Sound

 menu as 

HDMI ARC

.

Note:

 ARC is supported only via the HDMI2 input.

Enhanced Audio Return Channel 
(eARC)

Similar to ARC, the eARC feature enables the transfer of 
the digital audio stream from your TV to a connected 
audio device via the HDMI cable. eARC is an improved 
version of ARC. It has a much higher bandwidth than 
its predecessor. Bandwidth represents the range of 
frequencies or amount of data that is being transferred 
at a time. Higher bandwidth translates into a higher 
amount of data that can be transferred. Higher bandwidth 
also means that digital audio signal doesn’t have to be 
compressed and is much more detailed, rich, and vibrant. 

When eARC is enabled from the sound menu, the TV first 
tries to establish eARC link. If eARC is supported by the 
connected device, the output turns into eARC mode and 
the “eARC” indicator can be observed on the connected 
device’s OSD. If an eARC link cannot be established (for 
example, the connected device is not supporting eARC 
but supporting ARC only) or if eARC is disabled from the 
sound menu, then TV initiates ARC.
For eARC to function properly;

• 

The connected audio device should also support eARC.

• 

Some HDMI cables do not have enough bandwidth to 
carry high-bit-rate audio channels, use an HDMI cable 
with eARC support (HDMI High Speed Cables with 
Ethernet and the new Ultra High Speed HDMI Cable - 
check hdmi.org for latest info).

• 

Set the 

Sound Output

 option in the 

Settings>Sound

menu to 

HDMI ARC

. The 

eARC

 option in the 

Sound

menu will be enabled. Check to see if it is set to 

On

. If 

not, set it to 

On

.

Note:

 eARC is supported only via the HDMI2 input.

System Audio Control

Allows an Audio Amplifier/Receiver to be used with the 
TV. The volume can be controlled using the remote 
control of the TV. To activate this feature set the 

Sound 

Output 

option in the

 Settings>Sound

 menu as 

HDMI 

ARC

. When 

HDMI ARC

 option is selected, 

CEC 

option 

will be set as 

Enabled 

automatically, if it is not already 

set. The TV speakers will be muted and the sound of the 
watched source will be provided from the connected 
sound system.

Note:

 The audio device should support System Audio 

Control feature.

Game Mode

You can set your TV to achieve lowest latency for games. 
Go to 

Settings>Picture

 menu and set the 

Mode

 option 

to 

Game

. 

Game

 option will be available when the TV’s 

input source is set to HDMI. When set the picture will be 
optimised for low latency.
Auto Low Latency Mode
You can also enable the 

ALLM

 (Auto Low Latency Mode) 

option in the 

Settings>System>Device Settings

 menu. 

If this function is enabled the TV automatically switches 
the picture mode to 

Game

 when ALLM mode signal is 

received from the current HDMI source. TV switches back 
to previous picture mode setting when the ALLM signal is 
lost. So you won’t need to change the settings manually.
