Connecting Audio Output
Plug one end of the audio cable provided into the AUDIO OUTPUT JACK
(7). The other end should be plugged into your camcorder.
WLT-15 LAVALIER BODYPACK TRANSMITTER
• OFF/STANDBY/ON switch allows convenient audio muting with the
transmitter “ON”
• Low battery LED indicator flashes once for unit “ON”; lights steady for low
battery alert
Connecting Headphone to Monitor
You can monitor the received signal through headphones, and you will need
to monitor to set the transmitter’s level trim properly. Any “Walkman” type
headsets with a minijack or minijack adaptor can be used, though the signal
may be heard in only one ear unless a stereo-to-mono adapter jack is used.
• Locking 3.5mm mini-jack provides secure connection for removable
microphone or instrument cable
• Easily accessible input level adjust control for optimum sound
Operating Instructions
Monitoring through Receiver
Plug headphones into HEADPHONE JACK (8) on the receiver. The
ON/OFF/VOLUME WHEEL (2) controls volume to the headset. Set the
volume to a comfortable level by rotating the volume wheel. You will be able
to hear the received signal to the receiver when the system is operational.
This is the monitoring method necessary when adjusting the WLT-15
transmitter’s microphone input level per page 6.
1. Snap open the BATTERY COMPARTMENT (10) and insert a fresh 9V
BATTERY (11), observing the correct polarity. Close the compartment.
2. The WLT-15 is provided with a 3.5 mm LOCKING JACK (12) for
connecting the microphone. Plug in either the LAVALIER/LAPEL (13) or
the HEADWORN MICROPHONE (14), 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 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.
Monitoring through Camcorder
Many camcorders allow the user to monitor by providing a headphone jack.
If you plug your headphones into the camcorder, you may need to make a
simple adjustment on the 351 VR receiver. If the sound you hear is
uncomfortably loud or sounds distorted, turn the AUDIO LEVEL CONTROL
(9) on the back of the
receiver counter-clockwise
until good audio quality is
obtained. If volume is too
low, turn the AUDIO LEVEL
CONTROL (9) clockwise
until you obtain comfortable
volume.

(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.)

(8)
3. Turn on the WLT-15 by sliding the OFF/STANDBY/ON SWITCH (15) to
the STANDBY position (transmitter on, audio muted) or the ON position
(transmitter and audio both on). The BATTERY INDICATOR LED (16) will
give a single quick flash, indicating usable battery strength. In the case of
a dead or low 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 (6) on
the 351 VR receiver 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 instructions on page
5. Re-position the microphone farther from the source or adjust the AUDIO
INPUT LEVEL CONTROL (17) if the monitored volume is to loud or
distorted afer adjusting the receiver as per instructions on page 5.

WHT-15 HANDHELD MICROPHONE TRANSMITTER
• Features the Nady DM-10D unidirectional neodymium dynamic cartridge
for optimum true sound, maximum feedback rejection and minimal
handling noise
(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.)

Operating Instructions
1. Unscrew the BATTERY COMPARTMENT COVER (18) and remove,
exposing the BATTERY HOLDER (19). Insert a fresh 9V ALKALINE
BATTERY (20), observing the correct polarity as marked, and screw the
cover back on to the microphone. Make sure the cover is screwed on
completely. A fresh alkaline battery can last up to 15 hours in use, but in
order to ensure optimum performance, it is recommended that you replace
the battery after every 10 hours of use.

2. Turn on the WHT-15 by sliding the OFF/STANDBY/ON SWITCH (21) to
the STANDBY position (transmitter on, audio muted) or the ON position
(transmitter and audio both on). The BATTERY INDICATOR LED (22) will
give a single quick flash, indicating usable battery strength. In the case of a
dead or low battery, the LED will either not go on at all or will stay on
continuously, indicating that the battery should be replaced with a fresh one.
To preserve battery life, turn the transmitter off when not in use.
3. The microphone is now ready to use. The TX LED (6) on the 351 VR
receiver should now be lit, indicating a received signal from the transmitter.
When ready to speak, slide the transmitter switch to the ON position.

Receiver Volume Control Adjust
Turn volume control on the 351 VR receiver clockwise to near full gain.
Wearing a monitor headset plugged into the receiver's headset jack, speak
into the lavalier microphone. Adjust the receiver's volume to a comfortable
listening level.
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.
