Battery Maintenance
It is required to charge & discharge the battery at least every 3 months.
When charging, you are required to keep the machine in standby condition.
Indicator on the top the unit will blink while charging, and keep in light when charging is
almost completed that it requires additional 2~3 hours to complete the charging.
Thermal Printer Maintenance Residue and dirt on the thermal printer could affect the clarity of printing out ECG trace.
To clean the thermal printer, you are required to open the paper magazine and clean the
printer with soft cotton dipped with alcohol.
It is not permitted to operate on the printer with a sharp object.
Otherwise, permanent damage could be resulted.
Thermal printer maintenance should be done at least once a month
Printer Failure
Printer failure covers such circumstance that there will be some vertical break in the printed trace.Whenever a printer fault occurs, you are required to clean the thermal printer with soft cotton with alcohol. If this action does not work, certain thermal emitting component is probably damaged. If printing out trace is blurring, you are required to do as follows: â—ŹOpen the paper magazine. â—ŹAdjust the screw located below the printers shown in the following figure.
Lead Failure
Lead fault covers the situation that some lead does not give trace in the process of recording that is probably caused by the following. If you start recording immediately after the patient cable is connected to the patient, the unit will probably face problem of lead fault as a result of saturation or overflow at the baseline adjustment software due to receiving and working on unstable ECG trace & data. In such case, provided good lead connection is guaranteed, you’d better press key “RESET” to rapidly stabilize the trace of each channel or to try another recording, and everything will be OK. Damaged patient cable may also cause problem of lead fault. TO do checks on the patient cable, and contact our service technicians if it is damaged. The last reason for lead fault is the unit problem due to failure in signal communication. If you are sure to exclude other cause for this problem, please do not hesitate to contact our service technicians.
