WARNING
When using the NE-224S Sub-dermal Straight Needle Electrode
• Do not use the NE-224S sub-dermal straight needle electrode as a
measurement electrode for the EEG or evoked potential measurement
for any longer than one hour. When measuring the EEG or evoked
potential for over one hour, use the EEG disk electrode.
• Do not check the skin-electrode impedance when using a needle
electrode or intracranial electrode. Failure to follow this warning
injures the patient because these electrodes will be damaged by
electrolyzation inside the body.
• When measuring the patient with the implantable pacemaker, leave the
instrument (telemetry unit and access point) more than 22 cm from the
patient. Otherwise, the radio wave from the telemetry unit or access
point may interfere with the pacemaker.
• Do not delete any system file in the hard disk of the
electroencephalograph. Otherwise the electroencephalograph may
malfunction.
• Periodically back up the EEG data files to prevent loss of data if the
hard disk or MO disk is damaged.
CAUTION
• Do not use a device which uses Bluetooth® wireless technology and
wireless LAN device which complies with IEEE 802.11b near the
wireless input unit at the same time. If they are used together, the
radio waves interfere with each other. This may prevent the
communication between the telemetry unit and access point by
reducing transmission speed and transmission distance.
• Do not give impact to the telemetry unit. Spike noise may be
superimposed on the waveform.
• Use the provided pochette to hold the telemetry unit, electrode
junction box and/or isolator when they are attached to the patient.
• When moving the patient, make sure that the cable connected between
the isolator and access point is disconnected. Otherwise, the patient
may fall over the cable, or the cable may be broken.
• Do not shake or swing the telemetry unit holding the cable connected
to the telemetry unit. The telemetry unit may come off and it may
injure somebody or damage surrounding instruments.
