4. Operation Controls and Functions
4.1 Transmitter side
4.1.1 Front Panel
① Power: Press to turn the system on/off.
② Input: Press to select input source (1/2/3).
③ ID: Press the Transmitter and Receivers “ID” button for 2 seconds to
connect the systems. These systems were already connected before
leaving the factory, so you do not need to reset them again unless the
system cannot link up properly. Press the ID button for more than 10
seconds to switch to a different mode (Broadcast/Unicast). When the
green LED is lit it means the system is under Unicast mode and when the
red LED is on, it means the systems has been switched to Broadcast
mode. The factory default is Unicast mode and it is suggested to use this
for household use. It is not necessary to press both the Transmitter and
Receiver's ID button at the same time. Note: Due to the nature of the
transmission, Broadcast mode has no uplink so bi-directional
communication between Transmitter and Receiver is not possible. This
results in the following limitations:
• HDCP protected content should not be transmitted.
• CEC and EDID repeater functions are not supported.
• Broadcast mode is not HDCP compliant.
④ IR sensor.
⑤ Power: The LED will turn on when power is on.
⑥ Link: When under search mode the LED will flash repeatedly and during
the signal linking stage the LED will slowly flash. When the LED has been
switched on and no longer flashes it means the signal has been properly
linked.
⑦ Input indicator: The LED will turn on to indicate which input source is
being sent to the HDMI display.
