Channel Selection: Press the "SELECT" button to increase the channel number by one
(0-9, then A-F).* Press the ASC button, and the Channel Display will begin to flash. Hold the
transmitter’s (HH38 or MBP38) IR window towards and in close proximity less than 1.5 ft. to the
ECD receiver’s IR window. The ECD receiver’s RF Signal LED will light once
synchronization has been established. Only one IR connection can be established at a time
during each syncing process.
Receiver volume control:
Rotate the audio output level control knob to the left to reduce the output level, rotate to the right
to increase the output level.
*Note: When using multiple systems, it is best to set the maximum
channel spacing for each system.
