BM3 www.BIO2NET.com
1. Be sure that AC power supply line is appropriate to use.
(AC 100 - 240V)
2.Be sure that the power source is the one supplied from Bionet.
(DC 18V, 2.5A)
3.Be sure that the entire connection cable of the system is properly and firmly
fixed.
4. Be sure that the equipment is completely grounded.(Otherwise, noise
could result.)
5. The equipment should not be placed in the vicnity of electric generator, X-
ray, broadcasting apparatus to eliminate the electric noise during operation.
Otherwise, it may cause incorrect result.
NOTE
The Equipment should be placed far from generator, X-ray equipment, broadcasting
equipment, or transmitting wires, so as to prevent the electrical noises from being
generated during the operation, When these devices are near the Equipment, it can
produce inaccurate measurements. For BM3, both independent circuit and stable
grounding are essentially required. In the event that same power source is shared
with other electronic equipment, it can also produce inaccurate output
Warning
Do not use the System for any monitoring procedure on a patient if the monitor is not
working properly, or of it is mechanically damaged. Contact the hospital biomedical
engineer, or your supplier

occurrence of a patient. Main function
ns of the product include displaying information such as ECG, respiration,
SpO2, NIBP and temperature on its LCD screen and monitoring parameter,
and alarming. It also prints out waves and parameters via a printer.
Features of the Product
BM3 is a small-size multifunctional monitoring equipment for a patient
designed to an easy usage during movement. It features devices for auto
power supply (DC 10V-16V) and DC power supply (DC 18V) as well as
installing its handle to the patient’s bed. The equipment also measures major
parameters such as ECG, SpO2, NIBP, temperature and pulse, displaying it
on a 5.7-inch color LCD screen. It also enables users to check waves and
parameters and other vital signs of a patient via the 58mm thermal printer
and monitor the patient by the remote-controlled alarm system. It also
enables to build a central monitoring system by linking devices used for
separate patients so that one can monitor several patients at a time.
Warning
In order to avoid electrical shock, do not open the cover. Disassembling of the
Equipment have to be done only by the service personnel authorized by

patient including direct cardiac application. “Paddles” outside the
box indicate the applied part is defibrillator proof.
Medical Standard Definition : F-type applied part
(floating/insulated) complying with the specified requirements of
IEC 60601-1/UL 2601-1/CSA 601.1 Medical Standards to provide
a higher degree of protection against electric shock than that
provided by type BF applied parts.
TYPE BF APPLIED PART : I Insulated (floating) applied part
suitable for intentional external and internal application to the
