Introduction

This chapter introduces you to the M1700A PageWriter XLi, M1701A PageWriter XLs, and M1702A PageWriter XLe cardiographs and lists their technical specifications.

Warning

Note

These cardiographs are only to be serviced by qualified personnel.

Safe and effective use of medical instrumentation requires periodic inspection and preventive maintenance. Perform the preventive maintenance procedures in Chapter 4 of this manual at required intervals to ensure satisfactory instrument performance.

The cardiographs use a thermal printhead to record waveforms and label the ECG report. The paper supplied with the cardiographs is a special thermal paper designed specifically to work with the thermal printhead and the photo detector used to advance the paper.

The cardiograph’s clisk drive (M1700A & M1701A only) is a critical part. Disks of substandard quality can damage the clrive or destroy patient clata.

Hewlett-Packarcl guarantees the performance of the cardiographs only when used with paper and disks that meet or exceed Hewlett-Packard specifications.

PageWriter XL Cardiographs

The M1700A PageWriter XLi is Hewlett-Packard’s full-featured, interpretive cardiograph. The M1701A PageWriter XLs is the standard, non-interpretive cardiograph. The M1702A PageWriter XLe is the basic, non-interpretive cardiograph. Each cardiograph uses a patient module, which is a remote “front end” that acquires and digitizes clata. The M1700A and M1701A patient modules feature a start button ant1 an LCD display that indicates signal quality. The M1702A patient module does not feature a display or start button. The cardiograph main unit has the user controls, the disk drive (M1700A and M1701A only), the printer, and all the processing circuitry. All models use the same enclosure, except when the h41700A is equipped with preview display. The models fit onto the M1705A cart clesignecl for these carcliographs. Figure l-1 shows the M1700A with preview display mounted

the cart.

Introduction l-l

Figure l-l. M1700A PageWriter XLi Cardiograph with Preview Display.

The PageWriter XL family of cardiographs can print ECGs in Auto and Manual formats for different clinical tests or applications. Both cardiographs print all traces with a continuous feed, high-resolution, digital array printer. This produces electrocardiograms on standard page lengths that require

cutting or mounting. Records are clearly annotated with ECG data and patient information. The M1700A also labels records with automatic ECG measurements and ECG interpretation for both adult and pediatric patients.

The Ml700 ant1 M1701A cardiographs use flexible disks for storing ECGs. Exact ECG copies can be made at the bedside or Iater. Each ECG is automatically logged and can be automatically stored by the cardiograph. A list of all stored ECGs can be printed, facilitating administrative reporting and billing. Typically, 50-150 ECGS can be stored per flexible disk, although the actual quantity depends on usage.

From a service standpoint, the PageWriter XL cardiographs are similar except for five major hardware differences:

H The h41700A preview display allows you to view the ECG prior to

recording.

1-2 Introduction

The M1700A CPU assembly has extra nlenlory to accommodate the measurement and interpretation software, but uses the same ROM as the M1701A.

Each PageWriter has a unique CPU asscnibly.

The M1700A and M1701A load software from, and store ECGs to, the disk drive. The M1702A software is in ROM, and does not store ECGs.

The M1700A and M1701A patient modules feature a display that indicates signal quality and a start button. The M1702A patient module does not offer these features.

All other model differences are found in the cardiograph’s software. The M1700A and M1701A software is installed in the cardiograph from flexible disk, while the M1702A software is installed from ROM. After installation, the software is stored in dynamic RAM (DRAM).

Re-installation is required only when a user desires a different configuration, or if DRAM loses its contents due to a low battery.

The PageWriter XL family of cardiographs is designed for long-term reliability. The modular clesign makes extensive use of VLSI and gate array technology, resulting in a minimum number of major subassemblies. The modular approach means less down-time for the user, since replacing subassemblies allows quicker field repairs. The extended self-test efficiently identifies faulty subassemblies, further speeding the repair process.

Note

:’

M1705A Cart

As of February 1992, all new PageWriter XL cardiographs are manufactured to a revised mechanical design specification. All units having a serial number prefix of 3208A or later conform to this revised specification. This manual describes all specific differences.

The following paragraphs describe some of the significant options available for the PageWriter XL cardiographs.

The M1705A Cart provides mobility for the PageWriter XL family of cardiographs. The large wheels make the cart easy to move, yet steady when in use. Slots in the cardiograph’s feet and a thumbscrew secure the cardiograph to the cart rails, The tray directly below the

cardiograph provides storage for acquired ECGs, the user’s guide, and several flexible disks. The tray also has molded fittings that accommodate the modem in the M170GA/B Telecommunications Package. Storage for the power cable is built in, and other built-in cable retainers hold the patient clata cable out of the way. Two compartmented trays provide storage for the patient module, spare patient electrodes and leaclwires, additional thermal paper, consumable supplies, and miscellaneous items. An optional paper management tray is also available for the M1705A.

Introduction 1-3

M1706A/B

Telecommunications

Package

With the addition of the M1706A or M1706B Telecommunications

Package, the M1700A can transmit ECGs over telephone lines to another site. The receiver at the other site can be a Hewlett-Packard ECG Management system or another M1700A. This feature is not available for the M1701A.

The M1706A or M1706B Telecommunications Package consists of a Hayes@ modem, a bracket that attaches the modem to the cart, a power cable that connects to the modem power outlet on the cardiograph, and data cables that connect the modem to the cardiograph and the telephone system. Local laws, regulations, and phone system standards determine the specific type of modem and accessories included and the types of cables included in the M1706A or M1706B Telecommunications Package.

The original software for PageWriter XLi provides all basic features with preview display. This revision is only available for support purposes.

Refer any questions or comments regarding these instruments to the nearest Hewlett-Packard Sales/Service Office or to one of Hewlett-Packard’s Service Dispatch Centers. They can provide you with additional information about service training, special applications, and schematics. Always identify the instrument by model number and serial number in all correspondence. Hewlett-Packard sales and service offices are listed at the end of this manual. Toll-free numbers for Service Dispatch Centers are listecl in Chapter 8, “Parts List.”
