3.4 Infrared Remote Feedback
GM2400 wireless AV transceiver doesn't need specified remote,
but it has infrared remote feedback function. When emitting
source came from set-top box (STB), DVD, video camera with
remote function, remoter come with these equipments can be used
directly on the receiver (TRV2400), while you don't have to
operate the remote control of the AV equipments.
Step one:
Refer to connecting installation picture, connect transmitter
(TXV2400), and confirm there are no barriers between
transmitter's infrared window and infrared receiving window of
program source.
Step two:
When enjoying programs from receiver (TRV2400), point
remoter to remote receiving window of the receiver, then you can
control AV equipments, which is easy and convenient for
operation.
Tips:
Please pull 433 Mhz antenna of transmitter and receiver as
straight as possible, and keep it far away from AV cables,to ensure
no interference to signal transmission. In case of infrared remote
malfunction, please check antenna's placement on condition that
there is no placement problem with the transceiver.
