Operating Instructions
1. Snap open the BATTERY COMPARTMENT (10) and insert a fresh 9V
BATTERY (11), observing the correct polarity. Close the compartment.
2. The WLT 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.
(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 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 (4) on
the 151 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.

perspiration and saliva. It is good practice to put a windscreen on the mic element at all times to
protect it.)
