Step Four: Coat the coupling agent on the ultrasonic
probe
We recommend the liberal use of Ultrasonic, Aloe Vera or medical ultrasonic
coupling gel to reduce the static caused by moving the Fetal Doppler around on
the belly. Baby Oil, Coconut Oil, Virgin Olive Oil or even Vaseline work well which is
also readily available in most homes. Actually anything that lubricates the
movement across your belly will work. We do however suggest that you don't use
colored gels or lotions.
Caution: Be sure not to get coupling agent into the area around the On/ Off/
Volume dial as this could damage the unit.
Step Five: Listening to the Baby's Heartbeat

Fetal Doppler

1. Always check the Fetal Doppler on your own heartbeat first to make sure
everything is connected and working properly. Refer to the FAQs if it isn’t
before proceeding.
2. We recommend the mother be in a reclining position for easiest detection of
the baby's heartbeat.
3. Apply a generous amount of coupling gel to the receiver and to the
mother's abdomen.
4. Hold the receiver to the mother's heart first to hear how it sounds so
it's easier to distinguish from the baby.
5. Then hold the receiver to the mother's abdomen to listen to the baby's
heartbeat which should be much faster than mommy's heartbeat.
6. Move the Fetal Doppler very very slowly to find the optimum placement
based on the baby's current position.
7. After the heartbeat is detected, adjust the volume to a comfortable level
and enjoy.
8. After you are done listening, turn off the power and gently wipe the Fetal
Doppler clean but do not use cleaning agents or soap and water as this could
damage the unit.
Location and Detection
Detection of the Baby's Heart
Rate is detectable 90% of the
time after the 12th week
gestation.
Between 8 and 16 weeks it is
possible to hear the heartbeat if
conditions are perfect.
After the 16th week you should
have no problem finding the
heartbeat.

Fetal Doppler

The gestational chart shows about where you should be able to find your baby's
heartbeat as it grows each week.
Early in the gestation period place the receiver near the middle of the abdomen
above the pubic line but aiming down towards the pubic bone.
Move the receiver slowly while searching because the heart is so small and the
sound it makes so faint that it will be easy to miss hearing the heart if you move
too quickly.
Keep in mind that each mommy and baby is different so not being able to detect
the heartbeat early isn't a reason for concern.
If you are not able to detect the baby within 10 minutes we recommend taking a
break and trying again a few days later. However, if you are concerned about
any issues relating to your pregnancy you should contact your healthcare
provider for assistance.
As the baby grows, the heartbeats become stronger and it will be easier for you to
detect the sounds the baby makes.
We recommend keeping the session to less than 10 minutes at a time. we
recommend limited use in short intervals, infrequently and primarily after the
first trimester.
Make sure to continuously use plenty of coupling gel to reduce the static caused
by moving the probe around on the mother's belly. We recommend the use of
any of the following: Ultrasonic Gel, Aloe Vera, Medical ultrasonic coupling gel,
Baby Oil, Coconut Oil, Virgin Olive Oil or even Vaseline work well. DO NOT use
colored gels or lotions as this will not adequately protect the probe from
damage.

By counting the heartbeats for one minute you will be able to determine the
baby's heart rate in beats per minute (BPM). Do this at least 3 times and
average the results to get a more accurate reading.
A baby's normal heart rate should be between 110 and 160 BPM. The baby's heart
rate can vary based on the level of activity. Early in the pregnancy the baby's heart
rate will vary but as the baby matures the heart rate will become more consistent.
If you detect a heart rate in the range of 60 to 100 BPM then you are most likely
picking up the mother's heartbeats.
If you are concerned about the sounds you hear you should contact your
healthcare provider for assistance.
The Fetal Doppler is a listening system to hear the sounds your baby makes and is
NOT a medical device and can not be used for diagnostic or medical purposes and is
not to be used as a substitute for regular prenatal care by a licensed doctor.
Recording your Baby's Heartbeat
We recommend and encourage you to record the sound of your baby's heartbeat
on a smartphone. What a wonderful sound to share with your family and friends.
It would also be an amazing memory to share with your child as they grow older.
Once you have the Fetal Doppler connected, find the baby's heartbeat and then
begin recording. You may need to turn up the unit's volume up button to get the
best recording.
Tip: Record the mother's heartbeat also during this time and play it to soothe your
newborn baby in the nursery. Rather than a generic white noise heartbeat, wouldn't
it be better to use the baby's mother's heartbeat?

Principles of how the Fetal Doppler works
This Fetal Doppler consists of a receiver unit that can detect the slightest of
sounds inside the womb and sends signal output to a loudspeaker or a
smartphone.
A sound wave is transmitted from the Fetal Doppler to the uterus in the mommy's
belly and an echo is then received back when the sound wave bounces off of the
baby's heart.
The difference between these two signals (sound waves) are measured to
determine the baby's heartbeat.
Cleaning, Disinfecting, Care and Disposal
We recommend cleaning the gel from the transducer probe with a soft cloth. You
can disinfect the probe by wiping it with 70% ethanol or alcohol wipes and then
drying with a soft dry cloth. Do not use abrasives, solvents, bleach, soap and water,
steam or high temperature cleaning processes to sterilize the unit as any of these
can damage it. Do not immerse in water or liquids to clean the Fetal Doppler as this
will short out the unit.
The battery is recyclable. Please recycle the battery after use by following your
local recycling guidelines.

Product FAQs
Unit doesn't turn on -Make sure a fresh battery is installed and the power is
turned on. Check to make sure the battery connector is connected fully onto the
battery terminals. Make sure you’ve removed the clear protective wrapper off of
the battery.
The working indicator light is turns orange -Make sure a fresh battery is
installed.
There is no sound coming through the loudspeaker -Make sure a fresh
battery is installed and that the working indicator light is illuminated. Be sure to
turn up the volume using the Volume up button.
Uncomfortable noise is coming through loudspeaker -Make sure a fresh
battery is installed. A weak battery can cause noise. Interference can be caused by
nearby electronic devices (e.g. high frequency electronics, cell phones, cordless
phones, etc.). Make sure there is plenty of coupling gel between the probe and the
abdomen. Some slight noise does occur when moving the probe from one location
to another on the abdomen and sufficient lubrication will decrease this significantly.
How soon can I hear the baby -We recommend that the Fetal Doppler be used
after the 16 th week of pregnancy. Before that there are a lot of variables that may
not let you hear your baby yet. Keep in mind that the baby is tiny still before 16
weeks. The Fetal Doppler works more like a laser pointer than a floodlight in that
you will hear the baby when it is perfectly lined up. But the field of view of
detecting the baby is small, like a laser pointer, so if you are off slightly you’ll miss
the baby. As the baby grows each week, being able to find the baby becomes easier
and easier to do.

Fetal Doppler

I’m finding it difficult to find the baby after 16 weeks -First check to see if
you can hear your own heartbeat to be sure the unit is working correctly. If you can
not hear your own heartbeat then something is wrong and you should trouble
shoot first before attempting to locate the baby. Make sure to use sufficient
lubricating gel. Don't apply too much pressure to the mother's abdomen. You have
not yet found the optimum placement of the probe to hear the baby's heartbeat,
take a break for a day and try again later. Slow down moving the probe around on
the abdomen to make it easier to hear the heartbeat when you find the right
location. The baby can sometimes be located behind the placenta making it difficult
to find, try again later.
The battery cover doesn’t want to stay on –Please review the detailed
instructions on replacing the battery cover on page 6 for help.
How do I record the heartbeat –Please read the user manual of JUMPER
