than 2 seconds to enter scan mode, the
display will flash quickly. The receiver
will scan through the 100 operating
channels to find the optimal channel for
performance. Once the scan is complete,

and send the selected channel to the
transmitter.
Press and hold the button for
more than
10 seconds to enter IR set mode, the
display will flash slowly. This will send
the receiver’s current selected channel to
the transmitter.

channel.

the system is ready to use.

7. VOLUME / Power Control - This rotary
knob controls the level of the receiver
output and powers the AR99m on
and off. Turn the control clockwise
to turn the system on. Turn the knob
counterclockwise until it clicks to turn
the system off.
8. USB Port - This USB port provides 5V
200mA of power which can be used
to charge the AH9 headset transmitter
(AR99m only passes power to the USB
port when the power is ON). It can also
be used to connect an optional Samson
XPD USB Digital Wireless receiver to this
input, turning the AR99m into a dual
