PRECAUTIONS
PROBE
Non-invasive probes are for transcutaneous use only
Probe transducer tips are thin and delicate. Be careful not to drop or hit the probe tip. After
use, protect the transducer with the probe cap.
ULTRASOUND GEL
Use ultrasound gel. Use of other materials such as baby oil and cream may not produce
correct Doppler sound, and may damage the probe.
Not recommended with patients having a sensitivity or allergic reaction to ultrasound gel.
BATTERY
When battery is low, the power indicator will ash. Replace the battery.
Use only 9-volt alkaline batteries. A non-alkaline battery may cause a shortage of power.
When not using the unit for a long period of time, remove the battery.
MAIN UNIT
Do not place near water or other liquid, where atmospheric pressure, ventilation, sunlight,
dust, salt, sulfur, etc. may cause damage, or where chemicals are stored or gas may be
generated.
Use in environments where temperature is between 10° - 40° C and humidity is less than
75%.
Protect the unit from vibration and shock during transport.
Keep more than 1.5 meters away from computers or other information equipment.
Make sure that there is no damage to the unit or probe before use.
Do not use simultaneously with an electro cautery debrillator or other ultrasound device.
Please do not use the Doppler continuously for more than 1 hour to avoid the possibility of
skin irritation or rash.
The Doppler box should not have direct patient contact or be placed in the sterile eld as it
cannot be sterilized and reprocessed. If contact occurs, please see cleaning instructions for
cleaning the Doppler box.
The Doppler box and non-invasive probes should be cleaned following any patient contact
CAUTION: The ES-100VX has not been evaluated for safety and compatibility in the MR
environment. The ES-100VX has not been tested for heating or migration in the MR environment.
CAUTION: Perform ultrasound testing/procedures prudently using the principle of ALARA (As Low
As Reasonably Acheivable)

REPLACING THE BATTERY
Press down on the battery cover and slide
in the direction of the arrow, as pictured on
the right.
Place a 9-volt alkaline battery in the unit,
making sure that the positive and negative
electrodes correspond to the + and – marks
on the label inside the battery box.
Replace the battery when the power
indicator LED ashes.
TURNING THE UNIT ON & OFF
1. TURNING THE UNIT ON
Connect the probe with the arrow on the
probe connector pointing up (12 o’clock
position) and press the probe button to turn
the unit ON.
Turn the volume control to the desired level.
2. TURNING THE UNIT OFF
Press the probe button a second time to turn the unit OFF.
3. AUTOMATIC POWER OFF
If the unit is left on while not in use, the power will be automatically shut off after
approximately 3 minutes.
NOTE: Use only 9-volt alkaline
batteries. Use of non-alkaline batteries
may cause a shortage of power.
NOTE: The auto-off time is dependent on room temperature.

OPERATION (cont.)
4. Place the probe on the skin and
move slowly to locate the point where
maximum Doppler sounds are heard
(see below for your probe type).
[Pencil Style Probe]
If using the pencil style probe, hold the
probe softly against the measurement
area at an angle of approximately 45
to 60 degrees to the skin surface (see
gure A)
[Flat Vascular Probe (Model BF8)]
If using the at vascular probe, place the
probe over the artery, adjust to locate
the best sounds, and afx in place using
the velcro strap provided (see gure B).
[Fetal Probe (Model BT2M20S8C)]
When using the 2 MHz probe for fetal
heart beat detection, place the probe on
the measurement area at a 90 degree
angle (see gure C) and move slowly to
locate the point where fetal heart sounds
are at the maximum.

PRINCIPLES
The ES-100VX MiniDoppler® is designed to receive blood ow velocity information
through the use of ultrasound. A specic frequency is transmitted from the probe to the
patient.
The transceiver amplies a high frequency oscillation output for transmission to the
transducer. The voltage is converted by piezoelectric crystal (transducer) to ultrasound.
The ultrasound beam is transmitted to blood cells owing through arteries or to beating
fetal hearts. The ultrasound beam is reected by the red blood cells or by moving
structures and received by the crystal in the transducer, which converts the ultrasound
into a voltage. A Doppler shift occurs between the emission and reception of the
ultrasound beam.
The voltage is amplied. The electronics amplify the signal, lters out noise and
improves the S/N ratio. The Doppler shift signals are amplied further and converted to
audible sound via the integrated speaker.

Portable and mobile RF communications
equipment should be used no closer to
any part of the ES-100VX, including
cables, than the recommended
separation distance calculated from the
equation applicable to the frequency
of the transmitter

Interference may occur in the vicinity of
equipment marked with the following
symbol
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reection from structures, objects and people.
a Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To access the electromagnetic environment due to xed RF transmitters, an electromagnetic site survey
should be considered. If the measured eld strength in the location in which the ES-100VX is used exceeds the appli-
cable RF compliance level above, the ES-100VX should be observed to verify normal operation. If abnormal perfor-
mance is observed, additional measures may be necessary, such as reorienting or relocating the ES-100VX
b Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m
