High frequency interference by electrosurgery or energy discharged by a defibrillator may damage
the instrument. Follow the precautions described in the manual for each device.
(The instrument is protected against the energy discharged by a defibrillator only when the
accessory ECG extension cable is used.)
During electrosurgery, do not connect the ECG electrodes to the patient. (They may cause the
patient to be burned.)
Do not use a cellular telephone near the instrument. It could affect the instrument's operation.
The following points should be considered after use.
Follow a predetermined procedure to return the operation switches to their original positions, and
then turn off the power.
Do not forcibly pull out the cables and hoses.
Keep the instrument clean and in proper operating condition so that it can be used without problem
during the next operation.
Clean the accessories and arrange them before storage.
Perform the following when the instrument malfunctions.
Secure the patient’s or operator's safety.
Turn the power off and disconnect the power cable from the outlet.
Affix a notice such as “Out of Order” and “Do Not Use” on the device. Ask the nearest dealer for
services.
Do not disassemble or modify the device.
Perform regular maintenance and inspection of the instrument.
This is a precision instrument. Please check all functions and cables periodically.
If the instrument is used for the first time after an extended period of storage, check it for proper
operation.
Use a soft, dry cloth for removing stains from the instrument. Do not use solvents such as thinner or
benzine.
Strong electromagnetic waves may affect the instrument performance.
When the instrument is used near a strong electromagnetic field, it may malfunction and noises occur
in the waveform. If the instrument malfunctions unpredictably, check the environment for
electromagnetic fields and take adequate measures.
The following are typical causes of electromagnetic fields and measures against them.
Cellular telephones
Electric waves transmitted by a cellular telephone can cause the instrument to malfunction.
Turn off cellular telephones and other radio devices in medical facilities.
