Step3: Setup the IR blaster extender cable and IR sensor extender cable
If necessary, connect the Infrared (IR) blaster (or sensor) Extender cable. Users can point
hand-held remote control of your High Definition AV equipment at the receiver or the HDTV set
to operate the source devices, not exceeding the distance of 66 feet at Line-of-sight.
(1)
Plug the IR blaster cable into the IR OUT jack of the transmitter.
(2)
Please try to manually move the IR blaster in the front of the front panel of your HD device
and then press the key of remote control to search a good position of IR response. Paste the
IR blaster head near the front of IR sensor of your High-Definition audio/video devices.
(3)
When the IR blaster cable is connected, it relays infrared command from your remote control
to the device. Users can control their AV devices by pointing their remote control to the
receiver instead of to their AV equipment.
(4)
If the receiver will be out of the direct line of sight of your remote controls, plug the IR Sensor
Extender cable into the IR IN jack of the receiver and place the IR sensor on the front of TV
for operation.
Note:
(1) The IR sensor supports 36KHz ~ 56KHz (NEC, RC5, RC6) remote’s signal protocol. Therefore, it is
possible that some devices may not be supported.
(2) The IR blaster supports 47KHz remote’ signal protocol.
