IR Emitter Cable is Hall Research P/N CIR-EMT (recommended) you can also use

CIR-EMT2. Please check Hall Research website for further information.

4.0 Operation

The product is Plug-n-Play meaning that when connected as described in the

previous section, everything typically works with no issues.

If you have any issues such as no image or an image that is not centered or partially

cut off etc, on the connected TVs, it maybe that the generic default EDID is not

suitable for your source or TV. In that case, if the TV works when directly connected

to the Video Source, we recommend, "learning" the EDID from your display (to

substitute it for the default built in EDID).

4.1 Learning and Emulating EDID

By default, the LEARN EDID light is off. This means that the unit is using a generic

default internal EDID for the source that includes various PC and TV resolutions that

the UH-1D can support.

If your specific TV does not support some of the resolutions that the default EDID

reports to the source, you can "learn" the EDID from the TV used by following the

steps below:

1. Plug the TV to the Sender's HDMI OUTPUT port (the HDMI input can be

left disconnected, it does not matter)

2. Press and hold the MODE button for 3 seconds. The

LEARN light will blink a few times, indicating that the

device has learned your TV's EDID, and will stay on,

indicating that it is emulating the new EDID for the

source

To go back to the default EDID, press and hold the MODE button for 3 seconds. Just

tapping the MODE button will not change the EDID mode. This design feature

ensures that if a user inadvertently pushes the button the mode will not change.

Notice

If you try to learn EDID and a TV is not connected to the HDMI OUTPUT,

the unit will not learn any EDID and will continue using the default EDID.

The Sender will remember its EDID mode when power is disconnected.

If you Exit the Learn & Emulate mode, the sender will forget the learned

EDID. To go back, you have to Re-learn the EDID
