RMH-203 Hand-Held Radio-Microphone (40SFXMH)
Battery Installation
Unscrew the battery cover and insert a PP3 9-volt alkaline battery, being careful to observe the correct
polarity. Screw the battery cover back in position to hold the battery in contact. When the microphone is
switched on, the battery indicator should flash once. If no flash occurs, please check the polarity and make
sure the battery is a new one.
Operation
Switch on the microphone; the battery indicator should flash red once.
Switch on the amplifier, turn the volume up a little way and speak directly into the microphone.
Best results will be obtained by speaking fairly close to the grille (20 to 40 mm).
You can adjust the volume to suit your audience, but, to avoid feedback (high pitched whistling), do not point
the microphone directly at the loudspeaker or stand directly in front of the loudspeaker. If you are in a
confined space, turn the volume down.
When you are not using the microphone, turn it off to prolong the battery life
