RMT-103H/40SFXMT4 Belt-Pack
Transmitter
For use with the RMU-33 headset microphone or the RMU-50 lapel microphone
Battery Installation
Push and slide down to open the battery compartment. Fit a 9 Volt PP3 alkaline battery, being careful to
observe the correct polarity. Push and slide up to close the battery compartment. When the transmitter is
switched on, the battery indicator should flash red once. If no flash occurs, please check the polarity and make
sure the battery is a new one.
Operation
Headset Microphone
:
Follow the instructions provided with the headset microphone.
Lapel Microphone
:
plug the lapel microphone into the input socket of the belt-pack transmitter. Locate and
push the connector home and tighten the locking ring. Clip the microphone onto your clothing with the capsule
pointing upwards towards your lips. Best results will be obtained if you fix the microphone as close to your
mouth as possible. When speaking, try to keep you head level and pointing straight ahead so that the
microphone picks up your voice evenly. If feedback (high-pitched whistling) is a problem, reduce the volume
control on the belt-pack transmitter or the amplifier.
You can clip the belt-pack to your clothing or put it in your pocket.
Belt-Pack Transmitter:
Leave the GT-MT switch set to MT. Set the volume control on the belt-pack about half way up and use the
amplifier volume control to adjust the loudness to suit your audience. If you wish to adjust the volume while
speaking, you can do so from the belt-pack.
Switch on transmitter; the battery indicator should flash red once.
Switch on the amplifier, turn the volume up a little way and speak normally into the headset or lapel
microphone.
You can adjust the volume to suit your audience, but, to avoid feedback (high pitched whistling), do not stand
directly in front of the loudspeaker. If you are in a confined space, turn the volume down.
When you are not using the transmitter, turn it off to prolong the battery life.
