correct polarity. Close the compartment.
2. The WLT is provided with a 3.5 mm
in either the
LAVALIER/LAPEL (20)
connection, turn the metal slip ring on the plug clockwise to thread it on to the jack. To unplug,
reverse the process. Slip the transmitter into a pocket or clip on to your clothes. To use the
lavalier mic, attach it at chest level. Do not place too close to the mouth—a distance of about
six inches usually works best. To use the headworn mic, place it on the head and adjust the mic
boom so that the mic is about one inch to the side of the front of the mouth.
[Note: The lavalier or headworn mic wire is also the transmit antenna, and rolling up or
shortening the wire may reduce the effective operating range. Extend the wire fully during
use and keep it as straight as possible.]
3. Turn on the WLT by sliding the
on, audio muted) or the ON position (transmitter and audio both on). The
will give a single quick flash, indicating usable battery strength. In the case of a dead or low
(23)
battery, the LED either will not go on at all or will stay on continuously, indicating that the battery
should be replaced with a fresh one.
4. The microphone is now ready to use. The
should now be lit, indicating a received signal from the transmitter. When ready to speak, slide
the transmitter switch to the ON position and adjust the volume of the receiver as per the
Audio Output Microphone Connection section of the above 401X QUAD receiver instructions.

getting stronger. Occasional flickering on and off during use of the LED indicator in this display is
normal, however if the LED stays on continuously, it means the signal is too loud and there is the
possibility of overload distortion. Re-position the microphone farther from the source or adjust
the
AUDIO INPUT LEVEL CONTROL (24)
[Note: Observe care in selecting PA volume, transmitter location and speaker placement so that
acoustic feedback (howling and screeching) will be avoided. Please also observe the pickup
patterns of the microphone selected: omnidirectional mics pick up sound equally from all
directions and are prone to feedback if not used carefully. Unidirectional mics are more resistant
to feedback, but pick up sound sources best that are directly in front of the mic. Also, mics that
are farther from the sound source, such as lavaliers, require more acoustic gain and thus are also
more prone to feedback than close-source mics such as handheld or headworn mics that are
used close to the mouth.]
[Note: Microphone elements can easily be destroyed by the buildup of salts and minerals
from perspiration and saliva. It is good practice to put a windscreen on the mic element at
all times to protect it.]
