SAFETY NOTES
 The QOCA PORTABLE ECG MONITORING
DEVICE is to be used for clinical assessment and
personal reference only.
 The QOCA PORTABLE ECG MONITORING
DEVICE consists entirely of sophisticated medical
electrical parts. Maintenance can only be carried out
by professional technicians. Unauthorized
disassembly of the device by the user is not allowed.
 The QOCA PORTABLE ECG MONITORING
DEVICE must be used with its specified accessories
and electrodes. The use of accessories and
electrodes from other brands can damage the device
or cause inaccurate readings. For more information,
see Product Requirements.
 Do not allow the connectors or contacts on the
device’s to come into contact with any kind of power
source during use.
 Damaged or faulty accessories and electrodes
should not be used.
 When the QOCA PORTABLE ECG MONITORING
DEVICE is low on battery power, it will automatically
stop taking measurements and the corresponding
indicator lights will blink. Please charge the sensor’s
battery as soon as it shows a low battery state.

CIB418-01 6
 Avoid using devices that can affect the accuracy of
the readings when the QOCA PORTABLE ECG
MONITORING DEVICE is taking measurements
(e.g., using a blood pressure monitor will affect the
ECG’s pulse measurement).
 Avoid using other electronic devices when the QOCA
PORTABLE ECG MONITORING DEVICE is taking
measurements. If using another other electronic
device is necessary, please check to ensure the ECG
is continuing to take measurements normally. See
The Q-ECG App to see how to check if the device
taking measurements normally.
 Do not use the QOCA PORTABLE ECG
MONITORING DEVICE near open flames or in
excessive heat.
 When ambient temperature is 104°F – 113°F (40 –
45°C), do not use the QOCA PORTABLE ECG
MONITORING DEVICE because it may cause low
temperature burns.
 Users must purchase Sensor Holder、ECG
electrodes or Body Patch separately when using the
Sensor Holder or Body Patch. The specification can
be found in ECG Electrode Information.

CIB418-01 7
 Pay attention to ensure that the QOCA PORTABLE
ECG MONITORING DEVICE is not swallowed by
pets or children.
 Cardiac pacemakers or other electrical stimulators
may affect the accuracy of the measurements of the
QOCA PORTABLE ECG MONITORING DEVICE.
 The conductive parts of the electrodes and
associated connectors for type BF applied parts,
which are parts that make conductive contact with the
heart, including the neutral electrode, should not
make contact with other conductive parts including
the ground. Direct contact with other conductive parts
may result in electric shock.
 Please read through this user guide carefully before
using QOCA PORTABLE ECG MONITORING
DEVICE.
 If QOCA PORTABLE ECG MONITORING DEVICE
must be used to take measurements over an
extended period of time, please inspect the contact
point of the electrodes at least once every 24 hours
to make sure that the electrodes are in the right
position and that there is no allergic reaction on the
user’s skin.

CIB418-01 8
 Do not use high-frequency instruments or electrical
medical equipment such as defibrillators when using
the QOCA PORTABLE ECG MONITORING DEVICE.
 The QOCA PORTABLE ECG MONITORING
DEVICE can only take measurements while the
subject is stationary (e.g., while sitting or lying down)
or engaging in ordinary activity. Any activities not
permitted by the attending physician may affect the
accuracy of the measurements.
 Do not expose QOCA PORTABLE ECG
MONITORING DEVICE to extreme temperatures,
extremely moist environments, dust, or direct
sunlight.
 Do not clean the QOCA PORTABLE ECG
MONITORING DEVICE with corrosive or abrasive
cleaning agents.
 The QOCA PORTABLE ECG MONITORING
DEVICE and its accessories should be disposed of
properly. Disposal of the device and its accessories
should comply with the relevant local regulations.
 The QOCA PORTABLE ECG MONITORING
DEVICE has been tested and certified to international
electro-magnetic compatibility (EMC) standards for
medical equipment (EN 60601-1 and EN 60601-1-2).

CIB418-01 9
If abnormal behavior is observed due to EMC
disturbances, please relocate the device accordingly.
 Battery Caution: There is a risk of explosion if the
battery for the QOCA PORTABLE ECG
MONITORING DEVICE is replaced by an incorrect
battery type.
 The QOCA PORTABLE ECG MONITORING
DEVICE ’s use is not intended for use with infants
weighing less than 45lbs. (20 kg).
 The expected service life of the QOCA PORTABLE
ECG MONITORING DEVICE is 2 years.
 If you feel very itching or find redness when wearing
the body patch, remove the body patch immediately.
 Do not use QOCA PORTABLE ECG MONITORING
DEVICE in MRI or X-ray room.
 This device should not be used adjacent to or
stacked with other equipment.
 Please do not use any other cables or accessories
not approved by the manufacturer in this manual to
avoid negative influence on electromagnetic
compatibility.
 Due to electrostatic discharge (ESD) sparks may
cause sparks. QOCA PORTABLE ECG
MONITORING DEVICE is not suitable for use in an
explosive environment.

CIB418-01 10
 QOCA PORTABLE ECG MONITORING DEVICE
does not support with the devices that apply high-
frequency voltage to patients (such as electrosurgical
equipment and some respiratory sensors); if such
devices are used at the same time, it may cause
adverse consequences. For procedures that require
the use of high-frequency surgical equipment, QOCA
PORTABLE ECG MONITORING DEVICE should be
removed beforehand.
 Avoid using heavy electronic equipment or other
sources of electromagnetic interference (such as
electric blankets) when using the QOCA PORTABLE
ECG MONITORING DEVICE.
 When the ECG signal is always unstable, please
contact the manufacturer.

PRODUCT OVERVIEW
Indication for Use
The QOCA PORTABLE ECG MONITORING DEVICE is
intended for non-invasive measurement of a functional
Electrocardiogram (ECG) and heart rate (HR) in hospitals,
healthcare institutes, and home environments by trained
medical professionals and trained adult. The QOCA
PORTABLE ECG MONITORING DEVICE will process ECG
signals and calculate HR on continuous, spot check, or
event record mode. Users can also add time tags to the ECG
signals by pressing the button. ECG and HR data will be
transferred to a smartphone via Bluetooth and displayed on
the smartphone screen via a dedicated application called Q-
ecg. The data can be further transferred to cloud server for
storage.
The device should be worn on the human body along with a
body patch or a sensor holder with gel electrodes. The
QOCA PORTABLE ECG MONITORING DEVICE is
available to professional organizations such as home
caregivers, clinics, or hospitals. It is not available to the
general public. It should only be used by medical personnel
or trained adult patients. Use by unauthorized users is not
allowed.
