Introduction Important Patient and Safety Information
Important Patient and Safety Information
The PageWriter TC70 cardiograph isolates all connections to the patient from electrical
ground and all other conductive circuits in the cardiograph. This reduces the possibility of
hazardous currents passing from the cardiograph through the patient’s heart to ground.
WARNING Failure to follow these warnings could affect both patient and operator safety.
Accessories and Supplies
WARNING Always clean and disinfect reusable electrodes before patient use. Failure to properly
clean and disinfect reusable electrodes before patient use may cause infectious materials
to be transferred between patients.
WARNING The Welsh bulb electrodes (available as an accessory for the cardiograph) do not meet
the requirements of IEC 60601-2-25 for defibrillation recovery time, and cannot be
reliably used for patient diagnosis immediately following defibrillation.

Battery Level
Indicator
The Estimated Remaining Runtime and Power (bar indicators) may not be accurate. The
recommended intervals for battery calibration are dependent upon factors in your clinical use
model. When the battery power indicators are not functioning so that they are useful in your
daily work environment, Philips recommends calibrating the batteries following the procedure
described in this section.
The battery calibration procedure requires that the cardiograph be taken out of active use for
up to 8 hours. If this is not practical for your specific clinical environment, an optional battery
charger/calibrator s available for purchase from Philips Medical Systems, using part number
989803162021. For more information on ordering the optional battery charger and calibrator,
see “Supplies and Ordering Information” on page 1-33.

the report generated from the Service Utility screen. If the values are different, the battery
calibration procedure is complete.
PageWriter TC 70 Cardiograph Service Manual 2-15
Page 52
Cardiograph Care and Maintenance Maintaining the Touch Screen
NOTE If the Expected Max Error (%) field has not been reset to 2%, another calibration procedure
may be necessary. The max error value may not change if the full charge capacity has been
decreased by more than 256 mAh or increased by more than 512 mAh. If this occurs, another
calibration procedure is recommended as soon as it is convenient to further improve the accuracy
of displayed battery status information. For batteries with more than 8% of error, the maximum
error will remain unchanged if a limited calibration cycle occurs.
Maintaining the Touch Screen
The touch screen may require occasional maintenance, including calibration and cleaning.
Touch Screen Calibration
The touch screen may be calibrated at any time. Calibration is recommended if it requires
many attempts to select an item on the screen, or if selecting items on a specific area of the
screen is difficult.
The touch screen may also require calibration if the cardiograph is used in different settings

Troubleshooting Cardiograph Issues Troubleshooting
Signal Acquisition Issues
Before attempting to troubleshoot a signal acquisition error as a mechanical issue, ensure that
the following patient preparation and basic troubleshooting techniques have first been
followed.
Always follow good skin and patient preparation techniques prior to taking an ECG. Proper
skin preparation helps to ensure a good quality ECG. Skin is a poor conductor of electricity
and frequently creates artifact that distorts the ECG signal.
To prepare the patient for an ECG:
1
Shave hair from electrode sites if necessary (excessive hair prevents a good connection).
2 Wash the skin thoroughly with soap and water.
3 Dry the skin vigorously to increase capillary blood flow to the tissues and to remove the
dead, dry skin cells and oil.
NOTE Do not use alcohol to clean the skin because it dries the skin. If there is no time, rub the
electrode sites with gauze to remove the dead, dry skin and to increase capillary flow.
Always use disposable electrodes, and ensure that the disposable electrodes have not
4
expired. Place the electrodes on flat, fleshy parts of the arms and legs, and place all limb
electrodes equal distance from the heart, at the same position on each limb. If a limb site is
not available (amputation, injury) place the electrodes closer to the torso.
5 For female patients, always place the electrodes on top of the breast (not underneath the
breast tissue).
6 Ensure that all electrodes are firmly attached, and that the lead wires are not pulling on the
electrodes. If the electrodes can be moved easily, the electrode connection is too loose.
7 Reassure the patient and make sure that the patient is comfortable. If the patient has
tremors, attach the limb electrodes higher on the patient (closer to the torso), and assist
with limiting patient moving while taking the ECG.
After ensuring that proper patient preparation techniques are being followed, and that fresh
electrodes are being applied to the patient, review the following table for further assistance.

To test for open lead wires
Connect all of the lead wires to a metallic conductive surface, a shorting bar, or an ECG
1
simulator.
2 Touch the Map button on the cardiograph’s toolbar to open the lead map.
3 Ensure that no leads are being reported as leads off (red x mark ).
4 If any of the precordial leads report as leads off, with all limb leads connected, replace the
precordial lead(s).
5 If all leads report as leads off, replace the RL/N lead with a lead that is known to function
normally. If the new lead connected to the RL/N connector functions normally, replace the
defective RL lead. Once the RL/N lead is operable, proceed to replace any other leads that
display as leads off.
Running the Lead Wires Short Test
Use the following procedure to test for lead wire shorts.
To test limb leads
Disconnect all lead wires from the PIM.
1
2 Disconnect all lead wires from the patient or simulator.
3 Connect one limb lead wire to the PIM’s RA connector. Make sure that the post of the lead
wire is not in contact with any other lead wire posts or any other conductive surface.
4 Touch the Map button on the cardiograph’s toolbar to open the lead map.
5 Check that the RL lead shows a leads off (red x mark ).
6 If the RA and RL leads show a connection, with all other leads off, then the lead wire in
the RA connector has a short.
7 Repeat steps 3 through 5, connecting each limb lead (RL, RA, LL, LA) to the PIM’s RA
connector.
To test chest leads
Connect all the lead wire to the PIM.
1
2 Connect the limb leads to a metallic conductive surface, shorting bar or an ECG simulator.
Do not connect the chest leads.
3 Touch the Map button on the cardiograph’s toolbar to open the lead map.
4 Check that all limb leads show a connection.
5 Verify that all chest leads show leads off (a red x mark ).
6 If any chest leads show a connection, replace that lead wire.
