1.1.1 Warnings
WARNING
There is high voltage inside the system. Never disassemble the system
before it is disconnected from the AC power source.
The system must be connected to a properly installed power outlet with
protective earth contacts only. If the installation does not provide for a
protective earth conductor, disconnect it from the power line.
To completely disconnect the power supply, unplug the power cord.
To avoid the electric shock, disassemble the central charger after the
central charger is disconnected from the AC power source for five minutes
later.
Dispose of the package material, observing the applicable waste control
regulations and keeping it out of children’s reach.
1.1.2 Cautions
CAUTION
Make sure that no electromagnetic radiation interferes with the
performance of the system when preparing to carry out performance tests.
Mobile phone, X-ray equipment or MRI devices are a possible source of
interference as they may emit higher levels of electromagnetic radiation.
Before connecting the system to the power line, check that the voltage and
frequency ratings of the power line are the same as those indicated on the
system’s label or in this manual.
Protect the system from damage caused by drop, impact, strong vibration
or other mechanical force during servicing.
1.1.3 Notes
NOTE
Refer to Operator’s Manual for detailed operation and other information.

2Principles
2.1 System Operating Principle
TMS60 is a digital telemetry monitoring system consisting of the transmitter (TD60), the
receiver (RC60), the antenna array. The transmitter sends the patient’s physiological
information to the receiver, which then transmits the information to the Central
Monitoring System (CMS) for analysis, displaying, storage and printing. The transmitter is
attached to the patient, whereas the receiver is used together with the CMS. TMS60
telemetry monitoring system is intended to monitor and display a fixed set of parameters
including ECG, Resp, SpO2, N I B P, HR and PR under hospital environments. The Resp
module, SpO2module, and NIBP module are optional.
The following is a simple illustration:
Figure 2-1 TMS60 Telemetry Monitoring System Diagram
NOTE
The distance between the TD60 and the antenna should be at least one
meter.

2.2.2 Overview
The transmitter mainly consists of the MCU, ECG circuit, SpO2connector, WMTS circuit,
Bluetooth module, Power Circuit, and Display and Control Module.
The ECG circuit provides the amplified ECG signals, which supports 3-lead and 5-lead
modes.
SpO2module is externally connected to the transmitter.
WMTS circuit is to send ECG data, SpO2 data and status information out .The shielding
layer of the ECG lead is the transmitter antenna.
Bluetooth module is used to transfer configuration between the transmitters.
The Display and Control Module consists of a LCD, a touch screen, a LED indicator, a
speaker, and three keys. It is used to display ECG, SpO2waveforms and transmitter status,
etc, and allow users to control transmitter.

BeneVision TMS60 Service Manual 2-3
The MCU circuit is the core of the transmitter, enabling the following functions:
Button signal detection
SpO2connector
Status detection, such as ECG overload detection, lead off detection, PACE
detection, etc.
ECG data processing
MWTS circuit control and Baseband signal generation
Bluetooth module control
2.2.3 Receiver
2.2.3.1 Principle Diagram
Figure 2-3 Receiver Principle Diagram
The receiver comprises the AC/DC power source, power adapter board, amplifying and
branching module, 4-channel receiver, LED board, main control board and network
interface board.

2-4 BeneVision TMS60 Service Manual
2.2.3.2 AC/DC Source
The AC/DC source is to convert the externally inputted AC source into a 9V DC by means
of isolation. The inputted AC voltage range is from 90V to 264V, and the outputted
voltage/current is 9V/6.5A.
2.2.3.3 Power Adapter Board
The power adapter board is to drop the 9V DC coming from the AC/DC source to a 5V DC
and then output it with the 9V DC.
2.2.3.4 Amplifying and Branching Module
The amplifying and branching module is to amplify, filter and branch RF signals. The
module allows two amplifying, filtering & branching circuits with circuit parameters in full
symmetry. Each circuit amplifies, filters and branches the RF signals received by its
corresponding antenna and then outputs 4 channels of RF signals. Therefore, there are a
total of 8 channels of RF signals, which are then sent to the 4-channel receiver for
processing. The 9V DC linearly drops down to an 8V DC, which then goes to the
amplifying and branching module. The antenna array is shared by all receiving modules.
Therefore, in order to compensate for the branching attenuation of the signal, a LNA (low
noise amplification) is added before the branch divider. Besides, to avoid that the LNA is
blocked by strong out-band signal interference, filtering circuits shall be added in front of
and behind the LNA.
2.2.3.5 4-Channel Receiver
The 4-channel receiver divides the two channels of antenna signals coming from the
amplifying and branching module into four channels of RF signals through the 4-channel
branch divider. The MCU of the 4-channel receiving board will estimate the received
signal strength (RSSI) and then select the corresponding antenna signals through the
antenna switch. The selected signals will be respectively sent to the receiving modules for
filtering, amplifying, mixing, filtering and demodulating. The demodulated 4-channel
analog signals will then be sent to the MCU system for clock and data regenerating. The
regenerated data is packed by CPU and then delivered via the asynchronous serial port to
the main control board for processing. The 9V DC linearly drops down to an 8V DC, which
is then stabilized into a 5V and a 3.5 V supplying power for the 4-channel receiver.
2.2.3.6 Main Control Board
After receiving the data coming from the 4-channel receiving board, the main control
board will pack them and then delivers them to theCMS through the Ethernet. The
speaker of the main control board will give a short beep when the initialization is over,
and will beep continuously when an initialization failure or a hardware fault occurs.

BeneVision TMS60 Service Manual 2-5
2.2.3.7 LED Board
The LED board has two green LEDs, respectively indicating the power status and the
communication status of the receiving module.
2.2.3.8 Network Interface Board
The interface between the main control board and Ethernet consists of the network
isolating transformer and interface connector.
2.2.4 Central Monitoring System (CMS)
BeneVision Central Monitoring System comprises powerful system software and
high-performance computer components. It constructs a monitoring network by
connecting monitors and telemetry transmitters. By collecting, processing, analysing and
outputting the information coming from monitors and telemetry transmitters, the CMS
can achieve centralized monitoring over multiple patients so as to greatly promote the
efficiency and quality of the monitoring work.
The CMS is capable of connecting up to 32 telemetry transmitters.
2.2.5 Central Charger
The central charger inner structure consists of three boards, as shown in Figure 2-4:
