Warning @
As with all electronic equipment, radio frequency
interference between this cardiograph and any existing
RF transmitting or receiving equipment at the installation
site, including electrosurgical equipment, should be
evaluated carefully and any limitations noted before
the equipment is placed in service. Monitoring during
electrosurgery should not be attempted and monitoring
electrodes should be removed from the patient to
preclude the possiblity of burns. Radio frequency
generation from electrosurgical equipment and close
proximity transmitters may seriously degrade cardiograph
performance. Hewlett-Packard assumes no liability
for failures resulting from RF interference between HP
medical electronics and any radio frequency generating
equipment at levels exceeding those established by
applicable standards.
This is to certify that this equipment is in accordance
with the Radio Interference Requirements of the EMC
Directive.
Warning
Use of accessories other than those recommended by
Hewlett-Packard may compromise product performance
and/or product safety.
THIS PRODUCT IS NOT INTENDED FOR HOME
USE.

This chapter describesto the new user the many
features of the PageWriter 100cardiograph, patient and
operational safety, and AC/battery operation. The user
should becomefamiliar with this material, especially the
safety information, prior to using the cardiograph.
SeeAppendix A, Setting up Your Cardiograph for the
First Time for information on checking the voltage
switch setting, installing the battery, connecting the
cables, and loading paper. Each of these tasks must be
done prior to operating the cardiograph for the first
time.

A Instructions This text describes how the front-panel lights indicate the
operating status of the cardiograph:
Attention:
A flashing Auto light indicates that the ECG is being acquired.
When the light stays on, the acquisition is complete.
A flashing Chart Speed light indicates a paper supply problem.
A flashing Manual lead group light indicates an electrode
connection problem.

C Low Battery
D l-1
(g giiqz-SpeedJ

(TJ (\/)
(zJ=
Light will be on when the power cord is plugged into AC power.
This also indicates that the battery, if installed, is charging.
This light indicates that the cardiograph must be plugged in to
recharge the battery.
Switches the cardiograph between On and Standby. Standby
means the,cardiograph is off but it is still keeping the battery
charged as long as the cardiograph is plugged into AC power.
Sequentially changes the chart speed from 5, j 10, =+ 25, 3 50,
=+ 5 mm/second.
Sequentially changes the limb and chest lead sensitivity from 5, z+
10, 3 20, * 5 mm/mV.
Reduces the chest lead sensitivity to 50% of the value set by
g?CTiZSize).
Turns the Baseline Wander and Noise filters on or off. See “Auto
Report Filters” in Chapter 2, and “Manual Report Filters” in
Chapter 2 for more information.
Advances the paper to the beginning of the next page.
Starts an Auto ECG recording.
Starts a Manual ECG recording.
Sequentially changes the lead group used to generate a Manual
ECG from I II III, 3 aVR aVL aVF, j II aVF V2, j Vl-V6, j
I II III.
Halts any cardiograph function.
Prints a copy of the last Auto ECG. If you want additional copies
of an Auto ECG, you must print them before recording another
Auto or Manual ECG.See “Making Copies of Auto ECGs” in
Chapter 2, Recording an ECG for more information.

This guide contains conciseoperating instructions
for cardiograph users. This manual describeshow to
perform the following tasks:
n Recording an ECG
H Troubleshooting
n Caring for and maintaining the cardiograph
n Preparing your cardiograph for use
Getting Acquainted 1-7

Patient and
Your cardiograph isolates all connections to the patient
Operational Safety
from electrical ground and all other conductive circuits
Notes
in the cardiograph. This reduces the possibility of
hazardous currents passingfrom the cardiograph through
the patient’s heart to ground. To ensure the patient’s
safety and your own, observethe following reminders.
When operating your cardiograph from AC power, be
sure it and all other electrical equipment connected to
or near the patient are effectively grounded.
Use only grounded power cords (three-wire power
cords with grounded plugs). Also make sure the
outlet accepts the plug and is grounded. Never
modify a grounded plug to fit an ungrounded outlet,
i.e. removing the ground prong or ground clip to
fit an ungrounded outlet. Should an ungrounded
plug adapter be necessary,use a ground strap to
connect the equipotential connector at the rear of the
instrument to the power source ground.
The patient cable should be routed away from power
cords and any other electrical equipment. Failure to do
so can result in AC line frequency interference on the
ECG trace.
Warning
The HP patient cable supplied with this cardiograph, or an
approved HP substitute patient cable, is an integral part
of the cardiograph’s safety features. Using any other
patient cable may compromise defibrillation protection as
well as performance.
Only qualified personnel may service the cardiograph.
