HANDHELD TRANSMITTER OPERATION (C 8867C model)

1. Insert 2 x 1.5V AA size dry or rechargeable batteries. Note that fully charged rechargeable batteries will not provide power to the unit
as long as will good quality alkaline dry cell batteries.
2. Set the channel frequency inside the battery compartment, to match the receiver.
3. Press button for two seconds to turn on the microphone. The LED will stay on to indicate the batteries have sufficient power. If the
LED fails to light, the battery is either dead or not positioned correctly. If the LED stays flashing, it indicates that the battery will soon be
out of power and should be changed.
4. Set the levels on your audio mixer or amplifier as appropriate.
