USING THE T31 TRANSMITTER
The T31 Transmitter’s microphone cord is the transmitting antenna. Do not bunch up the
cord or wrap it around the transmitter. For maximum range, the cord should hang as straight
as possible. The transmitter can be placed in a pants pocket, or clipped onto a belt or waist-
band. Make sure the transmitter is turned OFF when not in use.
1. Make sure there are two charged AA batteries in the transmitter. If batteries are not
installed, see the section
Battery Information on page 10.
2. Plug the microphone cord into the “Mic” jack on top of the Transmitter.
3. Place the transmitter in the belt clip case provided.
4. Turn the power switch on top of the transmitter to “On.”
5. Clip the microphone onto a collar, lapel, or tie. It should be as close to the speaker’s
mouth as is practical. (See Figure 4.)
6. Turn the Mic Mute Switch to “On” when you are ready to speak. This switch allows
you to mute your microphone without turning off the transmitter. Listeners cannot
hear you through the system, and also do not hear the noise present when only the
receiver is on.
