2. Remove battery cover (see illustration 4),
remove battery housing and insert, in accordance
with the markings, 4 new and identical size AA
1.5 volt batteries, preferably alkaline. Replace
battery housing and close cover. Note: Please
dispose of used batteries in accordance with local
waste regulations.
3. Attach cords of the two sensor pads to the
double-connector of the connecting cable. Attach
end of connecting cable to the outlet marked
"SENSOR-IN" on the control unit.
When using a single sensor pad, attach cord
directly to the "SENSOR-IN" outlet without using
the connecting cable.
IMPORTANT: To avoid possible danger from
sensor cords, ensure that excess cord is secured
with the included cable tie.
4. Press hanging hook firmly into slot in back of
control unit (see illustration 4), and hang from the
edge of the bed, or anywhere out of baby's reach.
Infant Respiratory Monitor
During the first year of life, infants may experience
irregular breathing patterns or even stop breathing.
Babysense can alert when these signs indicate a
cold, high fever, or other illness. In the extreme,
breathing cessation can be related to Crib Death
(S.I.D.S: Sudden Infant Death Syndrome) still a
number one cause of death in infants up to one
year of age. The syndrome is impossible to predict
and modern medicine has not yet come up with
means of cure or solution, thereby "Babysense II"
is limited as a safeguard. However, it is a unique
safety system which has helped save infants, giving
parents (or caretaker) assurance, by enabling
intervention in the event of irregular breathing
movement or distress, before it becomes critical.
There are a number of cautionary steps which are
internationally recommended for SAFE SLEEPING:
*Always lay baby to sleep on his or her back.
*Refrain from smoking near or around baby.
*Avoid over-heating of baby's surrounding.
Babysense is an addition to these precautions.
Sensor Pads
(Under mattress)
Illustration 1
"Babysense II" is a home breathing movement
monitor for basically healthy infants, and is not to
be relied on for use with high-risk infants requiring
constant medical supervision.
Main Features
"Babysense II" continually detects baby's motion
and breathing movements, and will set off a sound
and visual alarm if movement stops for 20 seconds
or if the breathing rate slows to below 10 breaths
per minute. The system's non-touch sensor pads
under the mattress monitor baby's movement
without restraining him.
IMPORTANT: It is strongly advised that every
caregiver learn how to give first aid.
Note on installation for newborns
When using for infant not yet able to crawl,
use only one sensor pad - without the
connecting cable. (see illustration 2).
This will ensure greater relative sensitivity.
Make sure that the sensor is placed underneath
baby’s location in bed.
When baby begins to move around, and is able
to move onto areas not "covered" by the sensor
pad, the second pad must be attached, using the
connecting cable.
1. Place the two sensor pads on the bottom of the
bed (see illustration 1), or one sensor pad (see
note below on newborns). Place mattress firmly on
top of sensor pads. If the mattress cannot be in
contact with the sensor pads, or if the mattress is
on springs, it will be necessary to place a wooden
board on the bed base on which to place the
sensor pads, and then the mattress on top.

See illustration 3 for layout of control unit featuring:
• On/Off button under protective cover.
• Breathing movement indicator light.
• Red alarm light, activated if baby's breathing stops
or slows significantly.
• Low battery warning light.
When switched on, the red control lights switch on
briefly and a click sound will be heard. When
breathing and movement are sensed, the green light
If red low-battery warning light flashes (see
illustration 3), replace all batteries as soon as
possible. If in addition clicking is heard, all batteries
must be replaced immediately.
Turn off by pressing On/Off button.

Testing Operation
In the event of alarm
Act immediately according to the following:
1. Approach the bed and check that baby is
breathing. Note pallor (color of skin), muscle
tone and movement.
"Babysense II" is an exceedingly sensitive device
which monitors baby's breathing movements
through the mattress during sleep. There are two
main causes of malfunction- technical malfunctions
and malfunctions due to environmental factors.
2. If baby does not seem normal, pinch baby's
heel and check that there is no cause for
choking, such as an object lodged in baby’s
throat. When breathing resumes, consult a
Technical malfunction
In order to minimize technical problems, follow
installation and operation instructions carefully.
3. If breathing does not resume, apply first aid
and seek medical assistance immediately.
Environmentally caused malfunction
Due to the extreme sensitivity of "Babysense II",
it can be influenced by fans, wind, air conditioning,
and so forth. Such environmental effects could be
picked up by the sensors on a similar level to that
of breathing movements, thus preventing or
delaying alarm activation.
False alarms
Isolated cases of false alarms are possible. Check
if caused by faulty connection of the sensor pad(s)
to the control unit, connection of only one pad
when baby can move off the immediate area, or
failure of the sensor pads to be directly against
the mattress. A mattress of a stiff material such as
polystyrene foam could cause false alarms. It has
been noted that false alarms resulting from slow
breathing rate occur with one in about 200 babies.
Conduct this performance test daily
• Check that when baby is in bed, the green light
• Remove baby from bed and turn off device. After
turning off, wait 1 minute while the mattress
shifts due to removal of the baby's weight.
• Turn device back on and avoid moving or touching
the bed (without baby in bed).
• Watch for green light - blinking will indicate that
environmental disturbances are being read as
false movement recordings.
• Ensure that alarm goes off within 20 seconds (due
to absence of breathing movements). The alarm
may sound with or without preliminary ticking.
• Check that alarm can be heard in all locations
throughout the home or place of care.
• Performance test must be conducted daily.
Please contact your nearest BABYSENSE
representative with any questions or requests.
Please note
"Babysense II" monitors and alerts, but cannot
prevent cessation of breathing. The
responsibility for applying first aid rests on you.
"Babysense II" senses breathing movements and
motion only, and cannot monitor other
occurrences. The purpose of the device is to alert
when stopping or slowing of breathing and
movement occur, which could be associated with
common occurrences or even with S.I.D.S. caused
by APNEA (central nervous system failure) or any
other cause.
Locating and dealing with environmental
Caring for your "Babysense II”
If the alarm does not sound after 20 seconds,
eliminate all environmental disturbances by actions
such as changing ventilation, removing mobiles,
closing windows, repositioning bed and the like.
"Babysense II" requires no special treatment
beyond replacing batteries when the battery
indicator light goes on. The sensor pads and
remote unit may be wiped with a damp cloth.
Batteries should be removed and the device
stored in a dry shaded place when not in use.
Do not put any additional baby or pet in the bed.
Babysense cannot be used for two infants in one
bed. Do not operate vaporizer or ventilator directly
towards the bed.

movement that the device detects. For example,
sources of wind such as: air conditioner, an open
window or a fan; movements of a baby mobile (which
can vibrate even if it's not turned on) walking around
the bed area or an intercom placed near the bed with
intense transmission levels.
Solutions: Eliminate sources of wind, remove the
mobile etc.
After neutralizing all environmental interruptions,
perform the test again.
