For Any Help Concerning Set Up And Use Of Your Tv Please Call The Customer Helpline - Hitachi 50HYT62U Instruction Manual

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. Or press
Q.Menu button on the remote, highlight the CEC RC
Passthrough and set as Off by pressing Left or Right
button. This feature can also be enabled or disabled
under the Settings/Other Settings menu.
The TV supports also ARC(Audio Return Channel)
feature. This feature is an audio link meant to replace
other cables between the TV and the audio system
(A/V receiver or speaker system).
When ARC is active, TV does not mute its other audio
outputs automatically. So you need to decrease TV
volume to zero manually, if you want to hear audio
from connected audio device only (same as other
optical or co-axial digital audio outputs). If you want
to change connected device's volume level, you
should select that device from the source list. In that
case volume control keys are directed to connected
audio device.
