Introduction: Safety Information
contact with patients during defibrillation. Otherwise, 
serious injury or death could result. Patient signal inputs 
labeled with the CF and BF symbols with paddles are 
protected against damage resulting from defibrillation 
voltages. To ensure proper defibrillator protection, use 
only the recommended cables and leadwires. Proper 
placement of defibrillator paddles in relation to the 
electrodes is required to ensure successful defibrillation.
ELECTROSURGERY — If an electrosurgery device is 
used, it is necessary to disconnect the patient cable from 
the SEER Light recorder. Take precautions to reduce 
risks of burns and injury to the patient.
LEAKAGE CURRENT —   Electrical shock to patient 
could result from component failure and lack of power 
isolation. 
In the event this system is used in the patient vicinity, it 
must be configured in such a way that it and all of its 
electrically-connected peripheral devices are isolated from 
mains power to prevent excessive leakage current to the 
patient. This can be accomplished through the use of 
isolated mains power, or a medical grade isolation 
transformer (in compliance with UL 60601, CAN/CSA 
C22.2 No. 601.1, IEC 60601-1) with this system. All non-
medical peripheral devices shall comply with IEC and ISO 
safety standards that are relevant to that equipment (i.e., 
IEC 60950, UL 60950).
Use of the SEER Light Connect device in the patient 
vicinity requires that these measures are observed.
PACEMAKER PATIENTS — Take precautions to avoid 
risks of hazard due to the operation of a cardiac 
pacemaker or other electrical stimulators.
SUPERVISED USE — This device is intended for use 
under the direct supervision of a licensed health care 
practitioner.
