Safety
1.1 Intended Use
BT-750 is a patient monitor which displays state of patient’s data with wave form. Basic
functions are measuring ECG 3lead select and respiration. Also it is possible to
measuring arrhythmia, analysis ST level and detects pacemaker function. Other basic
functions are measuring SpO2, pulse rate, NIBP, 2 IBP and 2 body temperatures.
Optional functions are ECG 5 lead select and EtCO2 measurement.
Note : This device is for use only by trained medical personnel located in a treatment
room which is located in hospital, an operating room, a recovery room and an
intensive care unit.
Note : Because the incorrect use of this device can do patient’s life harm, this device
must be installed, used and operated by trained medical personnel who can
measure and analyze physiological signals.
1.2 Instructions for the safe operation and use of the BT-750
Examine the monitor and any accessories periodically to ensure that the cables, line cords,
transducers, and instruments do not have visible evidence of damage that may affect patient
safety or monitoring performance. The recommended inspection interval is once per week or
less. Do not use the monitor if there is any visible sign of damage. Do not place the monitor

Caution
BT-750 is intended only to measure and assess patient state. It must
be used in conjunction with Clinical signs and symptoms when
diagnosis is made.
Caution
The computerized ECG analysis should be judged by qualified
medical professionals, and should not be the sole basis in
determining necessity of treatment for the patient.
Caution

P/N : OPM(BT-750)EN Bistos Co.,Ltd. Rev.02(2013.04.12)
Caution
Classification of BT-750 :
- BT-750’s class is “Class IIb” equipment.
- It is type “CF grade”for ECG, Resp, IBP and “BF grade: for
EtCO2, SpO2, NIBP and Temp.
- The noise level is“ B” Class according to the IEC/EN 60601-1
(Safety of Electric Medical Product), and the noise redemption is
“B” Level according to the IEC/EN 60601-1-2 (Electromagnetic
Compatibility Requirements)
- Protection grade against water is“ IPX 0”
- Do not use this product around a flammable anesthetic and solvent.
Caution
Although BT-750 has been value of measurement in compliance
with existing EMI/EMC requirements, use of this system in the
presence of an electromagnetic field can cause momentary
degradation of the SpO2 waveform. If this occurs often, Bistos
suggestsa review of the environment in which the systemis being used, to
identify possible sources of electromagnetic waves. These waves could be
from other electrical devices used within the same room or an adjacent
room. Communication devices such as cellular phones and pagers can
cause these waves. The existence of radio, TV or microwave transmission
equipment located nearbycan cause electromagnetic waves. If EMI causes
disturbances,itmaybenecessarytorelocateyoursystem.
Electrostatic discharge (ESD), commonly referred to as a static
shock, is a naturally occurring phenomenon. ESD is the most
prevalent during conditions of low humidity, which can be caused by
heating or air conditioning. During low humidity conditions,
electrical charges naturally build up on individuals and can create
static shocks. An ESD condition occurs when an individual with an
electrical energy build-up comes in contact with objects such as
metal door knobs, file cabinets, computer equipment, and even other
individuals. The static shock or ESD is a discharge of the electrical
energy build-up from a charged individual to a lesser or non-charged
individual or object. The level of electrical energy discharged from a
system user or patient to the BT-750 can be significant enough to
cause damage to the system or probes. The following precautions can
help to reduce ESD: anti-static spray on carpets; anti-static spray on
linoleum; anti-static mats.

3. Battery charging starts once main power switch of rear side is on after AC Adaptor
connection.
4. Battery charged state displays in 5 steps.
Fullcharged 70%charged 50%charged 20%charged Discharged
5. When battery is low charged, battery state display on the screen is turned off, beep
sound generates and after about 5 minutes, power is disconnected automatically in
order to protect battery.
Note
When battery electronic pressure is in low state, it may cause
inaccurately measured value. Once battery state is low, connect AC
Adaptor to the appliance at once.
Note
For battery replacement, make sure of polarity.
If the battery polarity is placed incorrectly, it may cause fatal
problem on equipment.
Contact to Bistos head quarter or authorized agent, when you need
battery replacement.
If a side of power cord is put to power port of BT-750, power is supplied to the equipment. Make sure
that each cord is connected to input / output terminal correctly. If there is incorrect connection,
it may cause problem.
※Battery Charge
If AC power is disconnected, power is supplied thru battery. When battery power is not
sufficient, you should charge it by connecting AC adaptor.
Recharging time : More than 5 hours.
Duration time: Under 3 hours.
In the case of discharge battery.
Caution
Noise may occur in waveform, while using AC power. In this case,
ground the product.
It may occur the fatal damage to the product ,while connecting AC
power with wet hand.
Caution
While the monitor is working, battery charging lamp is on. When
sub-power switch is turned off and battery charging completes, lamp
is out.
