OPERATION  
MOUTING OPTIONS  
HDMI Input Indicators  
Wall Mounting  
The HM-31 has three HDMI Input Indicator lights on its front panel. When the HM-31  
senses audio/video transmission on one of its HDMI INPUT ports, the corresponding  
HDMI Input Indicator is illuminated in Red color. When an HDMI INPUT is selected for  
use, the corresponding HDMI Input Indicator is illuminated in Blue color. The HDMI  
Input Indicator is not illuminated when there is no input signal or no HDMI cable  
connected.  
The HM-31 HDMI Switch can be wall-mounted. To vertically mount the HM-31 HDMI  
Switch, please drill two holes on the wall using the included wall-mount template as  
guidance. Install appropriate anchors if necessary. Screw in two flat head screws into  
the holes or anchors, and leave approximately 1/16 inch space between the screw  
head and the wall surface. Hang the HM-31 HDMI Switch on the screws using the key  
holes on the bottom of the HDMI Switch. Due to the variation of possible mounting  
surfaces, mounting hardware is not included.  
Input Selection with the Front Panel Button  
There is an additional IR Remote Sensor on the top of the HM-31 HDMI Switch to  
facilitate wall-mount operation. Please make sure that it is not blocked to ensure  
reliable remote control.  
To select an HDMI input, press the SELECT button on the front panel of the HDMI  
switch. Each press of the button progresses to the next active HDMI INPUT. Signal  
from the selected HDMI INPUT is sent to the OUTPUT port and its corresponding  
HDMI Input Indicator is illuminated in Blue.  
Input Selection with the Remote Control  
ꢀꢁ  
Within about 25 ft  
ꢀꢁ  
The  
button on the remote control has the same function as the SELECT button on  
the front panel.  
There are also direct input selection buttons  
on the remote control.  
Pressing each button selects the corresponding HDMI INPUT port, no matter whether  
the port has active input signal or not.  
Automatic Input Selection  
Hidden Placement  
The HDMI INPUT ports 1, 2 and 3 are prioritized, with port 1 having the highest priority  
and port 3 the lowest. When the HM-31 HDMI Switch senses a new input signal on a  
port with higher priority than the currently selected port, it automatically switches to the  
high priority port. When input signal ceases on the currently selected port, the HM-31  
HDMI Switch automatically switches to the port with next priority and active signal.  
This priority makes it possible to automatically select input without touching the remote  
control or front panel. Simply turn on the desired source device and the HM-31 HDMI  
Switch will automatically select the correct HDMI INPUT port.  
If you would like to place the HM-31 HDMI Switch at a hidden location, please  
purchase an External IR Remote Sensor (OPPO part number IR-ES1) and plug it into  
the IR IN port on the back panel of the HDMI Switch. Place the sensor head at a  
location where there is direct line-of-sight to ensure reliable operation. The External IR  
Remote Sensor is available from your dealer or directly from OPPO Digital, Inc.  
Custom Installation  
For example, in the “Typical Connection” diagram on page 5, if you turn on the DVD  
player, the HDMI Switch will automatically select HDMI INPUT 1. To watch cable TV,  
simply turn off the DVD player and turn on the cable box. To play games, simply turn  
on the Game Console and turn off other devices.  
If your home theater system has an integrated control system, please ask your custom  
installer to contact OPPO for the RS-232C control protocol. The HM-31 HDMI Switch  
has an RS-232C control port and can be integrated into most custom home theater  
control systems.  
Note: Some cable box models have an active HDMI output even when they are turned  
off. In this case please connect the cable box to HDMI INPUT 3 so it has the lowest  
priority.
