80-0056-00-SM-RevD 2017-12-13 SunTech Tango M2 Service Manual | 3
1.0 Introduction
1.1 Before beginning any operation or service on the Tango M2, read and understand the user manual
(SunTech part number 80-0055-00), which is available for download from SunTechMed.com.
WARNING: ADDITIONAL WARNINGS AND CAUTIONS MAY BE FOUND IN THE TANGO M2 USER
MANUAL.
1.2 The SunTech Medical Tango M2 Non-Invasive Blood Pressure Monitor (NIBP) is used to obtain blood
pressure (BP) and heart rate (HR) readings during exercise testing. It can be used in conjunction with
most common Stress Test systems or as a standalone monitor when using a Tango M2 equipped with
internal ECG. The essential set-up consists of the monitor, pneumatic/K-sound patient cable, and Orbit-K
blood pressure cuff with K-sound microphone.
1.3 The Tango M2 is typically interfaced to a host stress test system and receives its analog or digital ECG
trigger via a coaxial cable with a BNC connection. Communication between the stress system and the
monitor is via an RS-232 null modem cable or USB-A (Stress System) to USB-B (Tango M2) cable. An
optional internal ECG board is available for standalone operation.
