PageWriter 100, 200, 200i, and 300pi Series Cardiographs The M1770A PageWriter 200i/300pi is Hewlett-Packard’s economical, interpretive cardiograph. The M1771A PageWriter 200 is the economical, non-interpretive cardiograph. The M1772A PageWriter 100 is the most economical, non-interpretive cardiograph. The cardiograph contains the user controls, the printer, and all the processing circuitry. All models use the same enclosure. The M1705B cart is designed for these cardiographs. Option #A05 provides transmission and storage capability for the M1770A and M1771A. The StressWriter option provides capability for communication between a PageWriter 100/200/200i/300pi cardiograph and a StressWriter system. The PageWriter 100, 200, and 300 family of cardiographs print ECGs in Auto and Manual formats. All PageWriter cardiographs use a continuous feed, high-resolution, thermal array printer. This produces electrocardiograms on standard- size paper that can be included in patient records without cutting or mounting. ECG reports clearly show the ECG waveforms. The PageWriter 200 and 300 series cardiographs also annotate records with patient information and ECG measurements. The PageWriter 200i and 300pi also includes ECG interpretation for both adult and pediatric patients. From a service standpoint, the PageWriter 100, 200, and 300 family of cardiographs are similar except for two major hardware differences: • The M1770A has additional firmware for ECG measurements and interpretation. • The M1771A has additional firmware for ECG measurements. • The M1772A keypanel does not have an LCD preview display and uses operational keys instead of alphanumeric keys for user input. All other model differences are found in the cardiograph’s software. The PageWriter 100, 200, and 300 family of cardiographs is designed for low-cost, longterm reliability. The modular design makes extensive use of VLSI and gate array technology, resulting in a minimum number of subassemblies. The modular approach means less down-time for the user, since replacing subassemblies allows faster field repairs. The internal self-test efficiently identifies faulty subassemblies, further speeding the repair process. M1705B Cart The optional M1705B Cart provides mobility for the PageWriter 100, 200, and 300 family of cardiographs. The large wheels make the cart easy to move, yet steady. 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 the user’s guide. Storage for the power cable is built in. Other built-in cable retainers hold the patient data cable out of the way. Two compartmented trays provide storage for spare patient electrodes and patient cables, additional thermal paper, and consumable supplies.
