Warnings & Cautions

Warnings

WARNING: There can be high voltage near the fuse, AC inlet and transformer. Always unplug the electrocardiograph before taking it apart.

Cautions

CAUTION: Always turn the electrocardiograph off and disconnect the power cord before cleaning. Do not pour liquids (such as alcohol or other cleaners) on the unit. This will cause severe electrical damage!

CAUTION: Setting the printhead resistance to any value other than the value written on the printhead will shorten the life expectancy of the printhead and may void your warranty.

CAUTION: Several of the electrocardiograph’s components are extremely sensitive to static electricity. To minimize the risk of damage, use a grounding strap and work on an antistatic surface.

CAUTION: The LCD is very sensitive to static electricity. Use an antistatic work surface.

CAUTION: The queue sensor is very sensitive to static electricity. Use an antistatic work surface.

CAUTION: The printhead is very sensitive to static electricity. Use an antistatic work surface.

CAUTION: The optional I/O board is very sensitive to static electricity. Use an antistatic work surface.

CAUTION: The front end digital board is very sensitive to static electricity. Use an antistatic work surface.

CAUTION: The power supply board is very sensitive to static electricity. Use an antistatic work surface.

Chapter					General Information

About the Atria Electrocardiographs

The Atria ECG is a multichannel non-interpretive/interpretive electrocardiograph. You operate the electrocardiograph by pressing various keys on the keypad. A thermal printer makes hard copy printouts of text and waveforms for permanent records.

The servicing of the Atria electrocardiograph 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 Atria electrocardiographs.

Basic System Description

A simple diagram of the system is shown in Figure . When AC power is not connected, an internal 14.4 V NiMH 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 (if equipped).
