1. Product Description
This product is a single-lead ECG recorder. It can record, display and analyze the ECG signals detected
through simple steps.
2. Product Features
1. Integrated design allows the recording and results being displayed on the cellphone screen for
bigger and better viewing.
2. Two types of recording tools (finger electrodes and cable electrodes) are supported for users’
convenience.
3. Discomfort marking feature allows users to mark the moment when discomfort of the chest is felt
during recording by pressing the power button. This feature helps physicians pinpoint the
problem.
4. It is a lightweight and portable device with 24-hour recording capacity. Recording can be done
anytime and anywhere without having to wait at a hospital.
3. Application
This product uses finger electrodes or cable electrodes to send the cardiac electrical current to the ECG
recorder to be recorded. Users may use this product with a physician’s recommendation and can operate
it without another person’s supervision. The recorder will provide real-time information to gain insight of
heart rate and rhythm. Users will receive results from a single-lead ECG. The device records, displays and
analyzes the ECG signals to aid physicians for further interpretation and diagnosis.

6. Instructions
6.1 Before using the product:
1) It is recommended to charge the device for more than 3 hours before first use.
2) Download the free Chiline app (scan the QR code on the packaging or on the back of the instruction
manual).
3) Go to “Settings” in your cellphone to turn on Bluetooth.
4) Press the power button for 3 seconds as illustrated in the image below until a green light appears.
Green light indicates that the device is on.
5) When all the above steps have been completed, open the Chiline app (main screen will look similar
to the image on the right)

4
6.2 Start recording
1) Open the Chiline app, then tap “Record an ECG”.
2) The cellphone will search for the ECG recorder. A blue light will remain on when the Bluetooth
connection is successful (below image).
3) Choose a recording mode, type of electrodes and duration in the Chiline app to begin recording.
6.3 Recording mode
This device supports two types of recording:
•Resting
•Ambulatory
(below image)
6.3.1 Resting mode
Two types of electrodes supported:
•Finger electrodes
•Cable electrodes (below image). Recording time is available for either 30 or 60 seconds. A result is

5
shown for every 30 seconds of recording (no result available for recording less than 30 seconds).
Finger electrodes:
Please follow the instructions in the app:
1) Rest both arms comfortably on a table. Orient the device so the power button is facing away from
you. Slightly press both thumbs on the front of the finger electrodes. Place index fingers at the
back of the finger electrodes but do not allow the index fingers to touch (below image). Stay
relaxed during the recording.
2) When the above steps are completed, the system will begin recording once an ECG signal is
detected (below image).
3) Real time display of waveforms is available in the app.
(Viewing available in both landscape and portrait orientations.)

6
4) When recording is completed, the app will display the results (below image).
(Viewing available in both landscape and portrait orientations.)
Cable electrodes:
Instructions for using the cable electrodes are the same as that for recording in “ambulatory mode”.
6.3.2 Ambulatory mode:
Only cable electrodes can be used in ambulatory mode. Do not use the device in a bathroom or in a humid
area and avoid strenuous activities while recording in ambulatory mode.
1) Recording time is available from one minute to 24 hours (below image). A result is shown for every
minute of recording (no result available for recording less than one minute).
2) Please follow the next two steps (below images):

7
Step 1: Plug the cable into the USB port.
Step 2: Attach the wires with the electrodes, then place the electrodes at the correct location on
the body (below image).
White electrode: Place at “RA”, below the right collarbone.
Green electrode: Place at “RL”.
Red electrode: Place at “LL”.
“RL” and “LL” are below the right and left rib cage respectively. They must align horizontally.
3) When the above steps are completed, the system will begin recording once an ECG signal is
detected.
4) Real time display of waveforms is available in the app (below image). The duration of waveform
displayed will depend on each cellphone’s performance. The device will continue to record offline
even if the waveforms are not displayed.
(Viewing available in both landscape and portrait orientations.)
5) Results are shown for every minute of recording.
(Viewing available in both landscape and portrait orientations.)
6) When recording is completed, the app will display the results.
(Viewing available in both landscape and portrait orientations.)
Results will show:

8
•Subject
•Total time recorded
•Number of discomfort marked
•ECG results, number of results and percentage of each type of result.
7) If “Recording offline” is tapped
or if the Bluetooth connection is off before the recording ends, the device will continue to detect your
ECG signals until the end of recording. After the recording, tap “Tap to transfer data” on the main
screen to upload data.
8) If “Recording offline” or “Record an ECG” (images below and to the right) is tapped before the
recording ends, the device will reconnect to the cellphone and real-time ECG waveforms and
results from every minute of recording after the reconnection will be available for viewing again.

(below image illustrates real-time waveforms)
9) When recording is completed, press the power button for three seconds to turn off the device (the
device will also turn off automatically after three minutes of inactivity).
Note 1: When recording in ambulatory mode, press the power button if you feel pain or discomfort in the
chest. The time when discomfort is felt will then be marked on the ECG report.
Note 2: When recording with cable electrodes, do not have directly skin contact with the device;
remember to store the main unit into the protective cover before placing the device into the pocket.
Note 3: If the Bluetooth connection is off when recording in resting mode, the recording will be terminated.
If it happens when recording in ambulatory mode, the device will switch to offline recording, and the
results will be available after the recording.
