0.1 General precautions, warnings and cautions
• Examine the patient monitor and any accessories periodically to ensure that the cables,
adapter cords and instruments do not have visible evidence of damage that may affect
patient safety or performance. The recommended inspection interval is once per week or
less. Do not use the patient monitor if there is any visible sign of damage.
• Only the DC power adapter supplied with the BT-720 is approved for use with the device.
• Do not attempt to service the BT-720 patient monitor. Only qualified service personnel by
Bistos Co. Ltd. should attempt any needed internal servicing.
• Perform periodic safety testing to insure proper patient safety. This should include
leakage current measurement and insulation testing. The recommended testing interval is
once per year.
• If the hospital or healthcare institutions using this device fail to implement a satisfactory
maintenance schedule, it will result in device failure and may endanger the patient’s
safety.
• Use the patient monitor under the conditions specified in this operation manual. Beyond
the conditions, the patient monitor may not function properly and the measurement
results may not accurate and may result in device failure or endangering the patient’s
safety.
• Do not operate the BT-720 patient monitor if it fails to pass the power on self-test
procedure.
• During the operation, do not disconnect any cable.
• The BT-720 patient monitor is intended to be used by clinical professionals or trained
doctors, nurses or laboratory assistant.
• Do not service and maintain or clean the device including accessories while in use with a
patient.
• Using the device to one patient at a time.

WARNING
An operator may only perform maintenance procedures specifically described in
• Thoroughly read and understand the manual prior to use of the BT-720. Failure to
do so could result in personal injury or equipment damage.
• The device is intended for clinical patient monitoring, and only trained and
qualified doctors and nurses should use the device.
• The alarm volume, upper and lower alarm limits should be set according to the
actual situation of the using environment. Do not just rely on audio alarm system
while monitoring the patient, because too low alarm volume or muted alarm may
result in notice failure of alarm situation and endanger the patient’s safety. Please
pay close attention to the actual clinical status of the patient.
• Use only the power adapter supplied with monitor.
• Position the monitor where it is easy to de-energize the monitor when needed.
• Do not open the enclosure to avoid an electric shock. Any repair and upgrade of
monitor should be done by service personnel trained and authorized by Bistos. Co.,
Ltd.
• When handling packaging materials, abide by local laws and regulations or hospital
waste disposal regulations. Keep the packaging materials away from children.
• Do not use in the presence of flammable anesthetics to prevent explosion or fire.
• Install the power lines and cables of accessories carefully to avoid patient
entanglement or suffocation, cables tangled or electrical interference.
• When the monitor is used together with electrosurgical devices, the user (a doctor
or a nurse) should ensure the safety of the patient and instrument.
• The physiological wave, physiological parameters and alarm information displayed
on the monitor are only for the doctor’s reference and should not be directly used
as the basis for clinical treatment.
• This is not a therapeutic device.
• For patients with pacemakers, the cardio tachometer may count the pacemaker
pulse in case of a cardiac arrest or arrhythmias. Never rely solely on the cardio
tachometer alarm. Closely monitor the patients with pacemaker. For the inhibition
of the device on pacemaker, refers to this manual.
• Use of accessories other than those listed and approved for use with this product
may result in increased emissions or decreased immunity.
• Medical electrical equipment needs special precautions regarding EMC and needs
to be installed and put into service according to the EMC information provided in
this manual. In addition, portable and mobile RF communications equipment can
affect medical electrical equipment.
• The equipment shall not be used adjacent to other devices unless verification of
normal operation in the configuration in which it is to be used can be achieved.
• Keep matches, and all other sources of ignition, out of the room in which the
patient monitor is located. Textiles, oils, and other combustibles are easily ignited
and burn with great intensity in air enriched with oxygen. Personal injury or
equipment damage could occur.
• A fire and explosion hazard exists when performing cleaning or maintenance
procedures in an oxygen-enriched environment.
• The patient monitor has been validated with the accessories and options listed in
this manual and found to comply with all relevant safety and performance
requirements applicable to the device. It is therefore the responsibility of the
person or organization who makes an unauthorized modification, or incorporates
an unapproved attachment to the device.

collision, strong vibration or other mechanical force.
• Avoid instrument splashed by water.
• Avoid high temperatures, the instrument should be used within a temperature
range of 5 ℃ ~ 40 ℃。
• Avoid using instrument in the environment such as pressure is too high, poor
ventilation, dusty, or contain salt, sulfur gas and chemical.
• Before using the monitor, check the monitor and accessories if there is damage
that may affect patient safety. If there is obvious damage or aging, replace the
parts before use. The replacement should be made with same parts of original
parts.
• Before powering on the device, make sure that the power used by the device
complies with the supply voltage and frequency requirements on the equipment
label or in the Operator’s Manual.
• Equipment should be tested at least once a year, the test should be done and
recorded by trained, have security testing knowledge and experienced personnel.
If there are any problems in the tests, they must be repaired.
• When the instrument and accessories are about to exceed the useful life
(expected service life: 5 years), it must be treated in accordance with relevant
local laws and regulations or the hospital's rules and regulations.
• Do not connect to other equipment or network which not specified in the
instruction for use, in risk of external high voltage.
• Do not connect any equipment or accessories that are not approved by the
manufacturer or according to IEC 60601-1 to the monitor. The operation or use of
non-approved equipment or accessories with the monitor is not tested or
supported, and monitor operation and safety are not guaranteed in such a case.
