b
Audio input port (Audio In) — Connect an MP3 player or other audio device
to this 3.5 mm TRS jack for auxiliary audio line input. When a device is
plugged into this port, its audio is mixed with either the internal microphone
or any external microphone connected to the Mic jack ( a ).
N Because the audio input is mixed with the microphone, pressing the Volume
button on the microphone affects the volume of the audio input device. However,
it is recommended that you use the volume control of the input device instead of
the microphone’s Volume button to control the levels of this audio input.

Volume button — Press the top part of this rocker button to raise the
microphone volume, and the bottom part to lower the volume.
When this button is pressed, the receiver produces a tone that signals that the

Pressing and holding both sections of this button simultaneously for
2 seconds sends an IR signal to the receiver to close its relay (Rly) port. (See
“Relay port”, later in this chapter, and chapter 4, “Special Application”, for
more information on this function.)

Charge jack — Connect a wall charger (5 V, 0.5 to 1 A) into this DC coaxial
