5 .0 OPERATING THE UNIT
These HDMI switchers have the following front panel controls:
INPUT Selection:
Use this push-button switch to select the desired input. Each time the switch is
pressed, the next input is selected in sequence (1, 2, 3, and so on). A Green LED
indicates which input is active.
ENHANCE Mode:
Press this button to activate a built-in cable equalizer, which helps to restore lost
high-frequency components of the HDMI signal if the input cable length is too
long or cable quality is questionable. When this mode is activated, a Yellow LED
will be turned on.
POWER On/Off:
This power switch turns the unit ON/OFF. A Red LED indicator turns on when the
unit is in the powered ON state.
5 .1 Operation of the HDMI Switcher via Remote Control
This HDMI switcher can be controlled using the
included Infrared Remote Control Unit. The switcher
can be turned ON or OFF and the inputs can be
selected by pressing the appropriate button on
the remote. Selection of the Enhance mode is not
possible from the IR Remote.
Note: When using the IR Remote Control for the first
time, it may be necessary to remove an insulator from
the battery compartment so that the remote can receive
power. The battery compartment slides out from the
bottom of the remote.
