HDMI CEC (RIHD)

Off

Setting to "On" enables the input selection link 

and other link functions with HDMI connected 

CEC compliant device.

"On": Use this function

"Off": Do not use this function

When changing this setting, turn off and then on 

again the power of all connected components.

● Depending on the TV set, a link may need to 

be configured on the TV.

● This function is effective only when the 

device is connected to the HDMI OUT MAIN 

terminal.

● When this setting is "On", the names of the 

CEC-compatible components and "CEC On" 

are displayed after this operation screen is 

closed.

● Power consumption in standby mode may 

increase if this setting is "On". (Depending on 

the TV status, the unit will enter the normal 

standby mode.)

● If you operate the MASTER VOLUME 

control on the unit when this setting is "On" 

and audio is output from the TV speakers, 

audio will be output also from the speakers 

connected to the unit. If you want to output 

from only either of them, change the unit or 

TV settings, or reduce the volume of the unit.

● If abnormal operation occurs when you set 

the setting to "On", set it to "Off".

● When connecting a non-CEC compatible 

component, or when you are not sure 

whether it is compatible, set the setting to 

"Off".
