Operation of Baby Control Digital breathing monitor
(BC-200, BC-210, BC-230)
The numerical display (2) will show the intensity of breathing movements detected by Baby Control Digital approximately
every 2.5 seconds („9“ - the most intensive, „1“ - the least intensive, „0“ - no movement detected). At the same time the gre-
en indicator light (6) will flash if the intensity of detected movement reaches or exceeds the pre-set threshold value. Thus it
is possible to check even from a distance whether the device has detected a movement that is intensive enough. An acoustic
warning signal will sound from the speaker (3) and the red indicator light (7) start to flash when the measured value does not
reach the pre-set threshold level four times in succession (12 seconds). Then the alarm is activated. If the measured value is
very low or equal to zero, it is likely that the mattress placed on the sensor padis extremely thick or baby is lying close to the
edge of the sensor pad (11). Please change this state to avoid false alarms.
IMPORTANT:
For the Baby Control Digital breathing monitor operation it is very important to adjust the
threshold level of detection, i.e. the value between „1“ and „9“ to be attained by the breathing movement
of the baby. Typically, the value „3“ is used (factory setting). You may change the setting in justified cases (see
Adjusting the threshold level of detection).
Adjusting the threshold level of detection
(BC-200, BC-210, BC-230, BC-220i, BC-230i)
IMPORTANT:
The factory setting of the threshold level of detection is „3“. This valueis optimalfor babies until
one year of age. Please change it only in justified cases.
The threshold level of detection of Baby Control Digital breathing monitor may be adjusted at nine levels. It may be necessary
to increase or decrease it according to situation. Please bear in mind that by decreasing the threshold level of detection, Baby
Control Digital breathing monitor will become more sensitive to false vibrations from the surroundings, while its increase may
make it more difficult to distinguish weak breathing movements! Therefore tests must be performed several times and very
carefullyalways after the threshold level of detection is adjusted (see Testing). A special attention must be paid to appliances
emitting permanent vibrations, such as air conditioning equipment, refrigerators, etc. If other value than „0“ is flashing on the
display and baby is not in the bed, Baby Control Digital breathing monitor detects vibrations from some place in its surroun-
dings. In such case do not use it until the source of vibrations is found.
The justified case for changing the threshold level of detection is e.g. when Baby Control Digital breathing monitor without
the baby’s presence shows any value higher than „0“ due to vibrations and it is not possible to keep these disturbing actions
from happening (e.g. strong traffic in the street). In such case please set the threshold level of detection by 2 levels higher
than is the highest value caused by such disturbance. You must be aware that by increasing the threshold level of detection
Baby Control Digital will not respond to tiny breathingmovements of the baby which may increase the false alarm probability.
This is mainly the problem with lower weight babies, whose breathing movements are weak even under normal conditions.
Sometimes, it may become necessary to set the threshold level of detection to „2“ or „1“, especially in the case of premature
babies with low weight; however one should proceed with great care when decreasing the level so that vibrations coming
from the surroundings do not influence the sensing. This may be checked on the display when the device is switched on and
the baby is not lying in the bed! In the absence of the baby, Baby Control Digital breathing monitor must sound an alarm
when in quiescent state.
