FREQUENCY SPECTRUM
This product uses 5GHz WIFI channels so it can be affected by outside interference in the same
way as any wifi device.
IR PASSBACK
If using a source device which has a remote control, this product allows the remote to be
pointed at the display in the remote location. The IR signal is relayed from the Rx to the Tx to
the source device.
To make this happen the IR blaster and receiver cables mush be used.
• The diode on the blaster must be as close as possible to the source IR receiver.
The diode on the receiver must be in line-of-sight of the remote control.
