3.2 Handheld Transmitter Setup
1. Insert battery. Slide open the hinged battery
compartment cover by placing your thumb on the
indents of the battery door (at the bottom of the
transmitter) and gently pushing down (see Figure
3). Insert the battery, terminal end first, into the
compartment, with the smaller positive terminal to
the right.
2. Set handheld transmitter channel to match the
channel setting on the receiver (channel number
displayed on front of receiver panel). The channel
setting on the handheld transmitter is accessed
through the round opening on the side of the mic
housing. Numbers 0 - 9 are printed around the
opening. The channel setting is determined by
which number the arrowed slot is pointing to. Use a
small screwdriver (supplied) to change the channel
setting. See Figure 4.
3. Turn on the transmitter by sliding the power
switch (closest to the battery compartment)
forward to the ON position (toward the windscreen).
The red battery condition light should flash once
and then go out. If the red light stays on or illumi-
nates during a performance, the battery should be
replaced immediately. The green light will stay lit
when the handheld transmitter is on.
NOTE: Remember to turn the transmitter OFF
when not in use. This will conserve battery life.
4. Verify reception. When the transmitter is turned
on, the yellow “Tx On” light, located on the front
panel of the receiver, will illuminate, indicating that
the receiver is picking up the signal. If this does
not happen, make sure that the transmitter and
receiver are set to the same channels.
5. Unmute the audio by sliding the audio switch
(immediately below the mic element) towards the
windscreen. Speak or sing into the microphone
and you should hear your voice through the
PA / sound system.
6. Adjustment of the transmitter audio gain - if
necessary. The transmitter audio gain is set to
a mid level which should be suitable for most
situations. However, for loud or soft speakers or
singers, an adjustment may be necessary. First,
speak or sing into the microphone and listen close-
ly. If the gain is too high, you will hear distortion,
and if the gain is too low, the signal will be low. In
either situation, an adjustment may be necessary.
To adjust the transmitter gain, gently insert the
provided screwdriver (or other 3/32-in. screwdriver)
into the hole near the head of the transmitter (see
Figure 4). Turn lightly until the screwdriver tip drops
into the slot in the level control. Gently turn counter-
clockwise until the control stops (the mic output is
attenuated but not “off”). Slowly turn the mic-level
control up while listening to the audio. If the audio
becomes distorted, turn the mic level control down
(counter-clockwise) about 1/8 turn.
NOTE: Operate with the transmitter audio gain set
as high as possible without distortion, for the best
signal to noise ratio.
7. Test performance. Check to see that the yellow
“Tx On” light on the front panel of the receiver is
illuminated, an indication that the receiver is picking
up the signal. Then, “walk” the intended area of use
and make sure that there are no barriers to
reception or sources of interference. If problems
are encountered, see Troubleshooting Guide.
