equipments are connected with the patient at the same time.
When the H3 electrocardiograph is used in conjunction with
defibrillator or pacemaker, do not allow the patient to contact bed,
table, metal or equipment.
In order to avoid burns, keep the electrodes far away from the
electrosurgical generator while using an ESU at the same time.
Only use the ECG cable or other accessories provided by Comen. The
accessories of other types may damage the equipment or affect the
performance and safety of the equipment.
Please ensure that all the electrodes are attached to the correct
positions on the patient body. Do not allow the electrodes (including
neutral electrodes) and patients to contact any other conductive parts
or the ground.
The operator should be trained professionally and thoroughly
understand the user manual before using.
Avoid liquid splashed on the equipment.
Avoid high temperature and the equipment should be used within
+5℃~+40℃.
Do not use this equipment in the environment with high pressure, bad
ventilation, dust, sulfury gas and chemical medicines.
Ensure that there is no strong electromagnetic interference source
around the installation and operation environment of the equipment,
such as radio transmitter, mobile phone etc. Large electrical equipment
such as ESU, ultrasonic equipment, radioactive equipment and MRI
equipment etc. are likely to generate electromagnetic interference.
Confirm that there is no mechanical damage on the equipment, ECG
cable and electrodes before using the equipments. If obvious damage or
aging is found on a certain part, replace this part before using.
Safety tests should be conducted periodically for the equipment, at least
