is recommended before power-on and operation.
1) Environment:
♦ Make sure that there is no electromagnetic interference source around the equipment,
especially large medical electrical equipment such as electrosurgical equipment,
radiological equipment, magnetic resonance imaging equipment etc. Switch off these
devices when necessary.
♦ Keep the examination room warm to avoid muscle tremor caused by cold.
2) Power Supply:
♦ If the mains supply is used, please check whether the power cord is connected to the

3) Patient Cable:
♦ Make sure that the patient cable is connected to the unit firmly, and keep it far away
from the power cord.
4) Electrodes:
♦ Make sure that all electrodes are connected to lead wires of the patient cable
correctly.
♦ Make sure that all electrodes are connected to the patient correctly.
♦ Ensure that the chest electrodes do not contact.
5) Recorder Paper:
