Welcome to the SunTech CT40
Thank you for choosing the SunTech CT40 for accurate spot-checking of vital signs.
The SunTech CT40 is designed to be simple and efficient to use and the CT40 features:
•mobility for improved and compact efficiency in a cost-effective package
•automatic BP checks
•averaging of multiple BP readings
•optional use of stethoscope for traditional auscultatory BP measurement
•robust memory
•connection to EMR system
•multiple options for pulse oximetry and temperature measurement
SunTech CT40 Description and Operation
The CT40 vital signs device can perform automatic blood pressure, pulse oximetry and body temperature
measurements for clinical professionals. For measuring blood pressure, a blood pressure cuff is placed around the
patient’s non-dominant upper arm. The cuff is inflated automatically and blood pressure is determined by the
oscillometric method—which senses pressure waves in the artery when occluded by pressure in the cuff.
Measurement of the frequency of the pressure waves enables heart rate to also be measured. The pulse oximetry
function non-invasively measures the patient’s percent oxygen saturation of arterial hemoglobin using principles of
plethysmography via a SpO2sensor placed on the patient’s finger. Temperature can be measured using one of two
different kinds of temperature probes. The oral/axillary/rectal temperature probe contains a thermistor that
generates a voltage based on changes in temperature, and these voltages are recorded by the temperature circuitry.
The touchless infrared temperature probe detects radiated infrared energy from the temporal artery. The CT40 is a
portable device, approximately 205 x 190 x 140 mm in size and weighs approximately 1440 g without battery. Control
buttons allow the user to stop/start a BP measurement, save a set of measurements to memory, change between BP
modes, and return to the home screen. There is also a selection knob that is used to scroll and select different device
options. The backlit LCD display shows the user device status and measurement information. The device uses a
microprocessor with software, which is not accessible to the user. The unit is powered by a single rechargeable
lithium-ion battery at the rear of the device. Two USB-A port connections can be used to connect, an optional printer,
barcode scanner or Wi-Fi dongle. There is also RJ11 Ethernet port for network connectivity, and a mini-USB port used
to connect the device to a PC or laptop for advanced device configuration.
Note: For purposes of this manual, the SunTech CT40 (Model 260) may be referred to as “the SunTech CT40,” “the
CT40” or “the device”.

adapters, have been intentionally disabled and will not function with this device.
Possible Adverse Reactions
In the area of the BP cuff or SpO2sensor, 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 or sensor.
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) may appear 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).
Warnings and Cautions
WARNING: 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.
WARNING: Pressurization of the cuff can temporarily cause loss of functionality of SpO2if simultaneously using
device on the same limb.
WARNING: Not designed for neonates.
WARNING: Do not apply the BP cuff to a limb being used for IV infusions as the cuff inflation can temporarily block
the infusion, causing harm to the patient.
WARNING: Check frequently by observing the limb that operation of the AUTOMATED SPHYGMOMANOMETER does
not result in prolonged impairment of the circulation of the patient.
WARNING: The cuff should not be applied over a wound as this can cause further injury.

Initial Power-up occurs the first time the device is turned on after being received from the factory, after the device
has been reset to factory defaults or after the battery has been changed. See “Monitor Setup” for information about
Initial Power-up.
Nominal Power-up refers to every time the device is turned on after Initial Power-up. Simply press the power button
and the display will illuminate.
NOTE: The blue LED around the Selection Knob will be lit whenever the device is powered on.
Power-down occurs when you press the power button when the device is powered up. During power-down, all LCD
segments and icons illuminate for 1 second and then the entire display gradually darkens from normal brightness to
black and then one beep sounds. At this point, the device enters Sleep Mode, a low-power state, and is considered
off.
Automatic Power-down occurs when the device has not been used (i.e., no measurements taken or buttons pressed)
for 1 hour. The device will automatically execute the Power-down sequence and enter Sleep Mode.
Your SunTech CT40 offers flexibility to function in ways that best meet your work setting.
Documenting Measurements
Before you start taking measurements, it’s important to document the patient ID per your facility’s procedures. In
order to do so, the barcode scanner must be used to enter the patient ID into the CT40.
With a Barcode Scanner
If your SunTech CT40 is connected to a barcode scanner, you can scan your patient’s barcode ID and it will show at
the top left of your screen. Then, the patient ID will remain attached to all measurements taken, saved in memory,
and/or sent to your facility’s EMR.

Without a Barcode Scanner
If you don’t require a barcode scanner, all measurement results will be displayed on the main screen and can be
saved to the device’s memory, written down in a chart, printed out (with optional thermal printer) or captured in
another way that meets your facility’s documentation procedures.
Printing
The SunTech CT40 can be connected to an optional SunTech thermal printer to easily print out measurement results.
See Section 11 for ordering information.
After connecting the optional CT40 thermal printer (see Section 2 and Section 3), ensure that the green LED on the
top of the printer is lit and unblinking before printing.
Reset Print
To print the information currently displayed on the CT40 screen, press the print button on the top of the printer (see
diagram above).
Saving Measurements
With EMR Connectivity
Technicians may have already connected the SunTech CT40 to your facility’s EMR system. If so, you can easily send
measurements directly to the EMR.
With the patient’s current measurements displayed on the screen, press the Memory button . The EMR icon
and Check Mark icon will begin flashing.
Press the Selection Knob to send the data to the EMR. If the measurements are delivered to the EMR successfully,
you will see the EMR Message icon and the Check Mark icon blink four times.
To store the displayed measurements in the device memory without sending to the EMR:
Press the Memory Button ,
While the EMR and Check Icons are flashing, turn the Selection Knob until the X icon is displayed and then press
the Selection Knob. The measurements will be saved to the device memory only.
Without EMR
The SunTech CT40 does not have to be connected to an EMR system to save measurements. You can save them to
the device’s own memory. With the patient’s current measurements displayed on the screen:
Press the Memory button .
All of the measurement values on the screen, the Check icon and the Memory icon will flash on and off 2
times.

The display will then return to a blank screen/shows null values, but the Check Mark icon will flash 2 more times,
this verifies the measurements are successfully stored to the device’s memory.
Note: The CT40 does not autosave. The user must save the reading to memory after every reading.
To view results stored in memory, press the Memory Button for more than four seconds. You will see the
most recently saved measurements displayed on the screen, and can turn the Selection Knob counterclockwise to
see older measurements and then clockwise to see newer measurements.
TIP: When you send results to memory, make note of the “Memory Location” number to keep track of an individual
patient’s measurements. Then later on, you can match the Memory Locator number with a patient’s name if you pull
up or print out results for documentation.
The memory will hold up to 99 records. At 100 readings the device will continue to save, but will save by overwriting
the oldest records.
5. Using SunTech CT40 for BP Measurement
The SunTech CT40 provides flexibility to allow you to measure BP using several different modes, depending on your
facility’s preferred procedure, the patient’s condition or other care considerations.
Step 1: Preparing the Patient
Patient Position
According to AHA guidelines, the patient should be seated for at least five minutes before taking a blood pressure
reading. The patient should be seated with feet flat on the floor and back supported. The patient’s upper arm should
be fully supported and resting at heart level. Encourage the patient to relax, and to be still and quiet.
Select and position BP cuff
Selecting the wrong size cuff will produce an inaccurate blood pressure measurement. When wrapped around the
patient’s arm, the Cuff Index Line should fall within the Range Markers printed on the cuff. If not, select a larger or
smaller cuff to ensure optimal BP measurement accuracy. The Artery Marker printed on the cuff must point to the
brachial artery, located inside the patient’s upper arm, between bicep and tricep. Wrap the cuff snugly around the
patient’s upper arm, so that the bottom edge of the cuff is approximately 1 inch above elbow joint.

Step 2: Select Between Adult Vs Pediatric Mode
The SunTech CT40 offers two different measurement modes for two very different types of patients: Adults and
Pediatric patients (children between the ages of 3 and 12).
To switch between Adult and Pediatric modes:
: Adult BP Mode icon : Pediatric BP Mode icon
Hold the Toggle Mode button down for 4 seconds until the adult and pediatric icons start blinking.
Turn the Selection Knob in either direction to select the desired icon
After making your selection, wait 2 seconds. The selected icon will be the one flashing.
Once you have selected the intended mode, press the Selection Knob to finalize this selection.
Note: Adult and Pediatric mode can be used in conjunction with any type of measurement mode.
Step 3: Select Measurement Mode
The SunTech CT40 offers three different ways to measure BP.
Automatic Single BP: You can take a single, automatic measurement (Single Measurement Mode).
Averaged BP : Automatically take and average up to 5 multiple BP measurements (Averaging Measurement Mode).
Auscultatory/ Sphyg mode. Allows you to verify an automated oscillometric BP reading with a manual auscultatory
measurement (Auscultatory SphygMode).
Note: Use of Auscultatory SphygMode may be required to meet certain clinical trial protocols. It also can be used to
verify a BP reading if the automated BP results diverge significantly from a patient’s prior history, or if you as the
clinician deem it necessary. Auscultatory SphygMode mimics a traditional sphygmomanometer and does not measure
Systolic or Diastolic blood pressure.
Note: Averaging Measurement Mode can only be used for Automatic BP Measurements. It cannot be used to
automatically average measurements taken in Auscultatory SphygMode.
Single Measurement Mode
This is the device’s default mode. The SunTech CT40 will be in this mode each time it is powered up
Pressing the Home button will revert to single measurement mode.
