Chapter 2 Security Notice
2.1 The power supply should be grounded properly before operation.
2.2 If the ground cable is not integrated, the device must run with built-in power supply.
2.3 Please pull out power supply plug before changing the fuse.
2.4 This device must be operated and preserved by professional personnel.
2.5 The operator must read this user manual carefully before operation, and operate the device
according to operation regulation strictly.
2.6 The design of this device has fully considered security, but operators should never neglect to
device state and patient’s situation.
2.7 Please turn off the instrument and pull out power supply plug before cleaning and disinfection.
2.8 Please don’t operate this device in environment which contains flammable anaesthesia gas.
2.9 If this device is used with cardiac defibrillator or other electric stimulate devices at the same
time, please choose Ag/AgCl chloride chest electrode and ECG lead with prevent-fibrillation
function. To prevent the metal electrode burn patients' skin, the disposable chest electrode should
be used if the defibrillation time is over 55 seconds. It is better that do not use this device with
other electric stimulate devices at the same time. If it must be used at the same time, there must be
professional technician guide on the scene.
2.10 When other devices are connected with this ECG instrument, they must be Type I devices
which accord with IEC60601-1. Because the total amount of leakage current may hurt patients, the
monitoring of leakage current is carried out and taken charge by connect devices.
2.11 Following descriptions concern special attentions in ECG measurement and interpretation:
(1) P wave and Q wave are not always reliable in the archive of intensive muscle artifact or AC
interference. So are the ST segment and T wave.
(2) Winding and unclear ends of S wave and T wave may lead to tolerance in measurement.
(3) In archive R wave is left out due to the low voltage of QRS wave or any leads falling off, the
measured heart rate may deviate greatly from the correct one.
(4) Axis calculation and identify the QRS borderline are not always reliable in the archive of the
low voltage of QRS wave.
(5) Occasionally, frequent ventricular premature complexes may be identified as dominant beat.
(6) Merging of versatile arrhythmia may result in untrustworthy measurement because of the
difficulty in distinguishing P wave in such situation.
(7) The device is designed to carry on ECG trace interpretation immediately after the
measurement. It is this interpretation that does not give report on all possible heart problems
and may sometimes not comply with the doctor’s diagnosis. Therefore, the final conclusion
concerning each patient is up to the doctor basing on patient symptom, the unit’s
interpretation and other examination.

Chapter 10 Electrode Placement
Advice: Set the chest electrode first, then the limb electrode.
10.1 Chest Electrode
See Figure 10-1:
Figure 10-1
Attach the chest electrodes to the locations as following:
V1: Fourth inter-costal space at right border of sternum.
V2: Fourth inter-costal space at left border of sternum.
V3: Midway between V2 and V4.
V4: Fifth inter-costal space at left mid-clavicular line.
V5: Left anterior axillary line at the horizontal lever of V4.
V6: Left mid-axillary line at the horizontal lever of V4.
Clean the skin where chest electrodes are to be attached with alcohol, then apply ECG cream to
here around 25mm in diameter and to the edge of chest electrodes, and press and attach the
electrodes to the positions from V1-V6.
Note: Keep in mind that the electrodes’ coming into contact with each other or cream’s
overlap from one position to another is not allowed.
10.2 Limb Electrode
Electrodes should be placed on the soft skin of hands and feet. Clean all the limb electrodes and
the positions around to which limb electrodes are to be attached with alcohol before applying ECG
cream to them, then firmly attach the electrodes to the positions. (See Figure 10-2)

Chapter 12 Precaution for Battery Operation
12.1 This instrument is designed with the built-in sealed maintenance-free rechargeable lithium
battery, and has automatic charge and discharge monitoring system. The instrument recharges the
battery automatically when connect to AC power supply. The LCD screen will show the current
power state at the top right corner when the instrument turns on (see 12.4). It needs about 4 hours
for battery charge after discharge absolutely.
12.2 The device can continuously print 90 minutes and work 4 hours without printing after the
battery fully charged. When it working, the LCD screen displays the signal of the battery
status in 5 degree. When the power of battery is too low to operate, the instrument will turn
off automatically to avoid damage to the battery.
12.3 The battery should be recharged in time after exhausted using. For long storage, the battery is
to be recharged every 3 months. The battery life can be extended by doing so.
12.4 Seven status of the battery power displayed on LCD as following:
Note: When charging, the battery icon shift from f to c.
12.5 When the battery can not be recharged or works no more than 10 minutes after fully charged,
please change the battery.
Attention:
Do not directly connect both "+" and "-" polars of battery with wire, otherwise it might cause
fire hazard.
Possible explosion hazard if it kept nearby the ablaze area.
You should not open or disassemble the battery.
