Warnings, Cautions & Notices

Warnings WARNING: This device is NOT intended for unattended or continuous patient monitoring. It is intended for short-term ECG waveform acquisition. There are no audible or visible alarms. WARNING: Never remove the battery pack and attempt to recharge it using an external battery charger. Fire or explosion may result. WARNING: Explosion hazard. Do NOT use in the presence of flammable anesthetics. WARNING: Electrical shock hazard. Do NOT contact unit or patient during defibrillation. Otherwise, serious injury or death could result. WARNING: NEVER position defibrillator paddles very close to or over ECG sensors. Remove all chest sensors (V-Leads/C-Leads) from a patient before defibrillation to allow proper paddle placement. Severe burns may result from improper placement of defibrillator paddles. Before using any defibrillator, consult the operating instructions for that equipment. WARNING: Electrical shock hazard. Operate the unit from its battery supply if the integrity of the protective earth conductor is in doubt. Otherwise, serious injury or death could result. WARNING: Hazardous voltage. To reduce the risk of electrical shock, do not attempt to remove the cover under any circumstances. Refer servicing to a qualified technician. WARNING: If safety procedures not performed, increased risk to patient and device can occur.

Cautions CAUTION: U. S. Federal law restricts this device to sale by or on the order of a physician. CAUTION: The unit must be operated only at the line voltage and frequency specified on the rating plate. CAUTION: Although the Eclipse is designed to meet IEC 601-1-2 EMC immunity requirements, the presence of strong EMI fields generated by electronic, surgical or diathermy instruments in close proximity to the unit may cause trace noise or input overload conditions. CAUTION: Fire hazard. Use only approved battery packs. Replace Eclipse 850 or Plus battery pack with the battery specified on the label inside the battery compartment.

Notices NOTICE: Do not place used battery pack in your regular trash. The incineration, landfilling, or mixing of NiCad batteries with municipal waste is PROHIBITED BY LAW in most areas. Return this battery pack to a government-approved battery recycler. Contact your local waste management officials for more information. NOTICE: Computer assisted interpretation is a valuable tool when used properly. However, no automated interpretation is completely reliable and interpretations should be reviewed by a qualified physician before treatment, or non-treatment, of any patient. NOTICE: Because the Eclipse offers different lead configurations, always ensure that the appropriate lead placement is employed for the lead configuration selected. NOTICE: Waveforms displayed on the Eclipse screen are not intended to be used for diagnostic purposes. Use displayed waveforms to assess signal quality only. NOTICE: Damage caused by using unapproved recording paper may void your warranty.Your Eclipse Electrocardiograph is intended for use with approved ECG supplies; its reliability and performance are directly affected by the supplies you use.

General Information

About the Eclipse™ Electrocardiographs The Eclipse™ ECG is a multichannel non-interpretive/ interpretive electrocardiograph. You operate the electrocardiograph by pressing various keys on the keyboard. A thermal printer makes hard copy printouts of text and waveforms for permanent records. The electrocardiograph can transmit and receive ECG records when used with other compatible equipment. See your Operating Instructions for additional information. The operation and servicing of the Eclipse electrocardiographs is similar regardless of which model you have. Some of the information in this Service manual applies only to options which you may or may not have installed in your electrocardiograph. Unless otherwise specified, the information in this Service Manual applies to the Eclipse 850 & Plus.

Basic System Description A simple diagram of the system is shown in Figure 1-1. When AC power is not connected, an internal 16.8VDC battery provides power for all functions. This battery is recharged whenever the AC line is connected. The ECG data is acquired by hybrid circuits and sophisticated software on the Logic board. Under microprocessor control, the electrocardiograph samples, buffers and amplifies the analog ECG signals before converting them to digital levels for further processing. Input/output control circuitry handles communication with the front end ECG signals, LCD (liquid crystal display), membrane switches, thermal printer and external devices such as a modem or other compatible equipment (if equipped).
