Service manual

v
• Before attempting to use the device for clinical applications the operator must read and understand the contents of the
manual and any documents accompanying the device.
• Where the integrity of external protective earth conductor arrangement is in doubt, the ELI 250/210 shall be operated from
its internal electrical power source.
• All signal input and output (I/O) connectors are intended for connection of only devices complying with IEC 60601-1, or
other IEC standards (e.g. IEC 60950), as appropriate to the device. Connecting additional devices to the ELI 250/210 may
increase chassis and/or patient leakage currents. To maintain operator and patient safety, consideration should be given to
the requirements of IEC 60601-1-1, and leakage currents should be measured to confirm no electric shock hazard exists.
• The ELI 250/210 has not been designed for use with high-frequency (HF) surgical equipment and does not provide a
protective means against hazards to the patient.
• The quality of the signal produced by the electrocardiograph may be adversely affected by the use of other medical
equipment, including but not limited to defibrillators and ultrasound machines.
• The ELI 250/210 uses a lead-acid gel cell battery. Disposal of this battery must be in compliance with governmental
regulations.
• This unit can operate using AC power. Caution should be taken when working on this unit to limit the exposure to high
voltages. The unit should not be connected to AC power and the battery fuse should be removed when replacing any
assembly of this unit.
