subject, their physical condition, and use outside of the operating instructions detailed in this guide. The
interpretation of blood pressure and oxygen saturation measurements should only be made by a physician.
Safety and effectiveness when used with pregnant women, children under 13 years of age and neonates have not
been established.

80-0055-00-MO-Rev F 2018-2-20 SunTech Tango M2 User Manual | 7
Pulse Oximetry
Use only Nonin pulse oximeter (SpO2) sensors supplied by SunTech Medical. Using other pulse oximeters may cause
improper sensor performance.
CAUTION: Check the application site of the SpO2 sensor frequently to confirm proper positioning of the
sensor and to check the circulation and skin sensitivity of the patient.
CAUTION: Monitor patient to ensure that all cables to the patient are secured to prevent entanglement with the
patient during the use of the Tango M2 system. If necessary, use the wrist straps to secure the cables to the
patient’s wrist.
CAUTION: Do not use a SpO2 extension cable with the Tango M2 system. An inaccurate SpO2 measurement may
result.
Factors that may affect the accuracy of pulse oximetry:
•electrosurgical interference
•arterial catheters, blood pressure cuffs, infusion lines, etc.
•moisture in the sensor
•improperly attached sensor
•incorrect sensor type
•poor pulse quality
•venous pulsations
•anemia or low hemoglobin concentrations
•cardiovascular dyes
•sensor not at heart level
•artificial fingernails and dark colored nail polish
Possible Adverse Reactions
In the area of the BP cuff, SpO2sensor or electrodes, allergic exanthema (symptomatic eruption) may result, including
the formation of urticaria (allergic reaction including raised edematous patches of skin or mucous membrane and
intense itching) caused by the fabric material of the cuff, sensor, or electrodes.
Following the application of the BP cuff, petechia formation (a minute reddish or purplish spot containing blood that
appears in the skin) or Rumpel-Leede phenomenon (multiple petechia) on the arm, which may lead to idiopathic-
thrombocytopenia (spontaneous persistent decrease in the number of platelets, associated with hemorrhagic
conditions) or phlebitis (inflammation of a vein) may be observed.
Warnings, Cautions, and Contraindications
Federal (U.S.) law restricts this device to sale by or on the order of a physician.
The Tango M2 NIBP monitor is defibrillator protected. The pulse oximeter is not defibrillator protected.
WARNING: No modification of this equipment is allowed.
Ensure that appropriate resuscitation equipment and personnel are available at all times during the procedure.
All alarms indicate a potential increased risk of injury if the test is continued.
DO NOT USE the monitor if it has failed its diagnostic self-test, or if it displays a greater than zero pressure with no BP
cuff attached, or a value of oxygen saturation with no SpO2sensor attached. The values displayed by such a unit may
be inaccurate.
DO NOT USE on neonates, children, and patients known to be readily susceptible to bruising.
This system is contraindicated for use in the presence of a Magnetic Resonance Imaging (MRI) device.
Do not attach the cuff to a limb being used for IV infusions or any other intravascular access, therapy or an
arteriovenous (A-V) shunt. The cuff inflation can temporarily block blood flow, potentially causing harm to the patient.

80-0055-00-MO-Rev F 2018-2-20 SunTech Tango M2 User Manual | 8
CAUTION: A compressed or kinked connection hose may cause continuous cuff pressure resulting in
blood flow interference and potentially harmful injury to the patient.
WARNING: Check periodically that operation of the AUTOMATED SPHYGMOMANOMETER does not result
in prolonged impairment of the circulation of the blood of the patient.
DO NOT apply the BP cuff over a wound as this can cause further injury.
DO NOT apply the BP cuff to the arm on the side of a single mastectomy. In the case of double mastectomy use the
side of the least dominate arm.
Too frequent BP measurements can cause injury to the patient due to blood flow interference.
Pressurization of the BP cuff can temporarily cause loss of function of simultaneously used monitoring equipment on
the same limb.
DO NOT attach the SpO2sensor to the same limb as the BP cuff or any other blood flow restrictors. Loss of
monitoring can occur due to the hindering of pulse measurements.
DO NOT USE in the presence of flammable anesthetics; this could cause an explosion. This monitor is not suitable for
use in an oxygen enriched environment.
Avoid compression or restriction of the patient cable tubing as it will affect the BP reading.
EXPOSURE TO FLUIDS: DO NOT immerse the monitor in any fluid, place fluids on top of, or attempt to clean the unit
with any liquid detergents or cleaning agents. This may cause an electrical hazard. Refer to the Cleaning section of
this guide for instructions on cleaning. If any of these situations occur, please contact SunTech Medical. Protection

Interval / Timer
•Timer displays in minutes & seconds.
•When the Interval is displayed as “EXT/MAN”, the monitor will take BP readings only when prompted, either by a
stress system or by a manual button press. The timer will count up from the end of the last BP reading. The clock
icon is inactive.
•When an Interval time is displayed, the monitor will take BP readings at timed intervals (also when prompted by a
stress system or by a manual button press). The timer will count up from the start of the last BP reading. The
clock icon fills in to show when the next reading will start.
•When in STAT mode, the red STAT icon is displayed. The timer will count up from the end of the last BP reading.
Waveform Display
•The waveform will normally show the K-sounds picked up by the microphone in the cuff. The waveform can be
set to display the ECG channel, but it will revert to displaying the K-sounds after 60 seconds.
Graph View
The Graph View screen displays a graphic summary of the most recent blood pressure measurements, in addition to
numeric display of the other readings available in the Measurement View.
An orange “running man” icon with a
slashed circle indicates that the monitor
is set to take blood pressure readings in
oscillometric (non-exercise) OSC MODE.
The patient must remain still.
A green “running man” icon indicates
that the monitor is set to take blood
pressure readings in auscultatory
(exercise) DKA™ MODE.
See the DKA™ MODE vs. OSC MODE section of this guide for more information.
Notes on Graph View:
BP Trend Graph
•The graph will display up to 15 readings at a time but will hold 50 BP readings. Use the UP and DOWN buttons to
