Connect the barrel end of AC/DC adaptor to the DC input of the back panel of
DAS-200, AC end to your AC outlet
Operation
Step 1. Please check the power is ok in either
Tx( the blue-ray LED will lighted on when
Plug into USB port )or Rx.
Step 2.Push the button on the Tx (as figure 1)
to select desired channel(the Receiver
can auto scan the channel that Tx has)
Step3. Turn on the audio amplifier at the Rx site
to check the audio quality, if there is some
interference occurred, the sound will has
some zigzag and buzz. At this time, you
