Features
This wireless microphone system is designed to be
used with a video camera recorder, etc. By attaching
the receiver unit onto a video camera recorder, etc.
you can receive the sound picked up by the
transmitter unit. You can enjoy vivid sound which
matches the zoomed up images recorded by your
video camera recorder.
You can also use this system with a tape recorder as a
conventional wireless microphone system to record
the sound.
•The operational distance between the transmitter
unit and the receiver unit can be up to
approximately 150 feet (45 m). However, this
distance may become shorter if there are some
obstacles in between the transmitter unit and the
receiver unit.
•The radio frequency can be selected so that a less
busy channel can be used while the air is busy.
•Compact design featuring built-in antennas.
•The transmitter unit is equipped with a plug in
power∗ type MIC jack (monaural/ 3.5 mm dia.) An
optional microphone other than the supplied one
can be connected to this jack.
•The transmitter and receiver units are equipped with
clip type holders with the adjustable clips which can
be rotated 360 degrees so that the transmitter and
receiver units can be attached onto your clothes etc.
with optimum angles.
•The receiver unit is equipped with the MIX MIC jack
to which an optional microphone such as the ECM-
T145 (lavalier microphone) can be connected, so that
the sound transmitted from the transmitter unit can
be mixed with the sound picked up by the optional
microphone.
•The receiver unit is equipped with the v (earphone)
jack to which the supplied earphone can be
connected, so that you can monitor the sound being
recorded. You can use the earphone connected to
the receiver unit to monitor the subject using the
transmitter unit.
•The supplied lavalier microphone has a built-in
wind screen effect so that you can use the
microphone in the open air without a wind screen.
∗Plug in power system
The system that power is supplied directly to the
microphone from the microphone jack of the
connected equipment.
Precautions
This wireless microphone system uses FM radio
waves for transmission. Therefore, there may be cases
where the transmission of the sound may be hindered
when the system is used near certain obstacles. FM
radio waves may also be deflected by walls etc.
Under such circumstances, the sound may be
intermittent or distorted at times. However, these are
the characteristics of FM radio waves and this does
not indicate a malfunction.
•The system should never be dropped or subjected to
extreme shock.
•Keep the system away from extremely high
temperatures (above 140° F or 60° C) and humidity.
•Do not use this system in the following locations as
doing so can cause microphonics (electrical
disturbance noise) which will impair the
performance of this system.
—A very noisy (more than 70 phone) location.
—A location with a lot of vibration.
—A location near a rotating machine or a
transformer.
—Near a speaker of a PA system.
—Near recording studio equipment.
•You do not need to have a license to operate this
microphone system. However, observe the
following points.
—Avoid using the system near a broadcasting
station, airport or inside an airplane.
—If radio interference from other radio equipment
occurs, alter the radio channel or change the
location. (You are not protected by law against
any radio interference caused by other radio
equipment .)
•When this system is connected to a radio cassette
player, etc. and the system's lavalier microphone is
placed too close to the speaker of the radio cassette
player, acoustic feedback (a howling effect) may
occur. If this happens, change the direction of the
microphone until the howling stops, or decrease the
volume of the radio cassette player.
•When using the system outdoors, avoid getting the
system wet.
•Should any liquid fall onto the system, wipe it
thoroughly with a dry soft cloth.
•The system is a monaural type.
Therefore, if you use this system with equipment
capable of stereo recording, the recorded sound will
become monaural.

Turning off the system
Turn off the receiver first, then the transmitter.
The maximum distance that the radio
transmission can reach
The optimum distance is up to approximately 150 feet
(45 m) without the system picking up some
interference. However, the distance may vary
according to the surroundings and environment. If
the system picks up some noise while using it within
the above mentioned distance, reduce the distance
between the transmitter unit and the receiver unit.
To record the ambient sound in the vicinity
of the video camera recorder at the same
time
Connect the optional microphone to the MIX MIC jack
of the receiver unit. You can mix the sound
transmitted by the transmitter unit and the sound
from the optional microphone.
