Safety Measures- The power supply need to be grounded properly before operation

• In case of doubt the grounding cable is faulty, make sure to use only the internal (built-in) power supply to run the device
• Please unplug the power supply cable before changing the fuse
• This device must be operated by trained and expert medical personnel and maintained by a qualified expert
• The user must read this user manual before operating this device, strictly following the instructions within
• Even though the device is designed to fully meet the safety conditions, the user must monitor the device operation and observe the patient's condition
• Please turn off the device and unplug the supply cable before cleaning and disinfecting the device
• Please do not use this device in the vicinity of flammable anesthetic gases
• The device can be used on heart directly. In case the device is simultaneously used with a heart defibrillator or other electric stimulation device, please use precordial Ag/AgCl electrodes and ECG-cables with the defibrillation option. In case defibrillation takes longer than five seconds, single-use precordial electrode must be used instead of a metal one which would burn through patient's skin. It is not recommended to use this device simultaneously with other electric stimulation devices. In case it is necessary, a technical expert must be present and issue instructions.
• Notes regarding ECG-waveform measurement and analysis:
• (1) Recorded P and Q-waves ware not always accurate in case of EMG and AC interference. The same applies for ST-segment and T-wave with baseline shift
• (2) In case of winded or unclear ends of S and T-waves, faulty measurement might occur
• (3) If case of device not registering the R-wave due to unplugged electrodes or low QRS-wave voltage, measured recordings of heart pulse might be inaccurate
• (4) In case of low QRS-wave voltage, ECG axis measurement and QRS-wave borderline identification might not always be accurate
• (5) Occasionally, the device might register frequent premature ventricular contraction complexes as dominant heartbeats
• (6) A combination of multiple arrhythmia types might cause unreliable measurement due to P-wave identification difficulties in such situations
• (7) The device has a built-in function for auto-analysis which analyses only the ECG-waves that have been recorded, meaning it doesn't apply to all conditions a patient might be subject of. The analysis results might not be in line with a doctor's diagnosis. Therefore, the conclusive diagnosis for each separate patient depends on a doctor's diagnosis based on analysis results, patient's symptoms and other applicable examinations.

• In case of using the device simultaneously with a high-frequency surgery device, keep electrodes away from the scalpel to prevent burns and cable burnout caused by high-frequency sparking.
• In case of using the device simultaneously with a defibrillator, make sure not to touch the patient or bed, as well as taking care an ECG electrode doesn't come in contact with a defibrillator electrode in order to prevent sparking from a burning device or patient.
• Do not use this device in case of interferences caused by heavy-duty equipment. Moreover, keep it away from interference sources such as headphones or cell phones.
• When the device or any of its accessories reaches its expiration date, it is necessary to dispose of it in accordance with environment protection guidelines and local legislatives and laws.

• In case of using the device simultaneously with a heart defibrillator or other electric stimulation devices, please use precordial Ag/AgCl electrodes.
• In case defibrillation takes longer than five seconds, single-use precordial electrode must be used instead of a metal one which would burn through patient's skin.It is not recommended to use this device simultaneously with other electric stimulation devices. In case it is necessary, a technical expert must be present and issue instructions.
• While the device is running, a doctor must be present, carefully monitoring the patient at all times. Unplug the device or remove the electrode/s in order to ensure patient's safety and well-being.
• Once you are done with using the device, return all functions to their default positions before turning off the device. Carefully remove the electrodes; do not yank them forcefully. Clean the device and its accessories.
• Overload, amplifier saturation and electrode unplugging might cause the device to stop running.
• Regular maintenance must be performed on the device and all its accessories (no more than a year must pass without regularly performing maintenance)
• Electrocardiograph is a type of measurement device and needs to be regularly tested in accordance with local laws.
