WLT Lavalier/Lapel or Headworn Microphone
Bodypack Transmitter
1. Snap open the
BATTERY COMPARTMENT (17) and insert a fresh 9V BATTERY (18), observing the
correct polarity. Close the compartment.
2.TheWLTisprovidedwitha3.5mm
LOCKING JACK (19) for connecting the microphone. Plug
in either the
LAVALIER/LAPEL (20) or the HEADWORN MICROPHONE (21), as supplied. To secure the
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

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

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
TX LED INDICATOR (7) on the 401X QUAD receiver
should now be lit, indicating a received signal from the transmitter. When ready to speak, slide

[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.]
