Battery Maintenance and Care
Caring for the Battery
The battery must be installed for proper operation of the cardiograph. The cardiograph cannot 
print an ECG report without the battery, even if it is plugged into AC power. 
The sealed lead-acid battery used in the PageWriter Trim cardiographs will provide optimal 
longevity when the batteries are fully charged after each use. A depleted battery requires 
sixteen hours of continuous charge time to fully recharge. Because it is not always possible to 
allow a full charge cycle between uses, the cardiograph was designed to charge a depleted 
battery to 90% of its capacity in approximately eight hours. 
CAUTIONRepeated undercharging of the battery will damage the battery and reduce overall battery life.
NOTEPhilips recommends that the cardiograph be plugged into AC power whenever possible to maximize 
battery life.
Battery life varies depending on frequency of use and maintenance, and environmental 
conditions when the battery is used or stored. For improved battery life, keep the cardiograph 
plugged in when not in use. If the battery has been fully charged and requires recharging after 
a few ECGs, consider replacing it. 
For optimal battery performance:
„Only use Philips Medical Systems lead-acid battery (Philips part number 989803130151) 
with the cardiograph. 
„Keep the cardiograph plugged into AC power at all times when not in use.  
						

							Cardiograph Care and MaintenanceBattery Maintenance and Care
PageWriter Trim Cardiograph Service Manual3-7
„If the battery has been fully charged and requires recharging after a few ECGs, consider 
replacing it. 
„The use of cardiograph accessories (barcode reader, magnetic card reader, PC card, 
modem) will deplete battery power at a faster rate. The battery will require more frequent 
charging if these accessories are used with the cardiograph.
NOTEThe battery should be removed and placed in storage if the cardiograph will not be used for more 
than thirty days.
Storing the Battery
Remove the battery from the cardiograph if it will be stored for more than thirty days without 
use. While in storage, the battery will require a full recharge every six months. Charge the 
battery for at least sixteen hours to ensure that the battery does not completely discharge while 
in storage. Battery life will be prolonged when stored in cooler temperatures, but will be 
damaged if stored below freezing (0
 oC/32o F). Store the battery at a temperature of 40 oC 
(104o F) or lower. The recommended ideal battery storage temperature is 25 oC (77o F).
To store the battery:
1
Charge the battery for sixteen hours before removing it from the cardiograph. Ensure that 
the AC power cord is connected to the cardiograph and is plugged into a grounded AC 
power outlet. Check that the green AC power indicator light on the front of the 
cardiograph is lit. 
2After charging is complete, remove the battery from the cardiograph and store it in a cool, 
dry location. For information about removing or replacing the battery, see Chapter 7, 
“Removing and Replacing Cardiograph Components.”
3Recharge the battery for sixteen hours every six months while battery is in storage.

Replacing the Lead Wires in the PIM
To replace the lead wires:
1
Disconnect the PIM from the RJ-11 receptacle (rear of cardiograph).
2Remove the lead wire(s) by pulling the connector up.
3Match the lead wire labeling (on lead) with the same lead wire connector on the PIM.

4Reattach the patient data cable to the RJ-11 receptacle (rear of cardiograph).
WARNINGTo ensure safety and prevent damage to the system, only connect the patient data cable 
to the correct PIM connector on the rear of the cardiograph. 
Cardiograph and Accessory Disposal
When the cardiograph has reached the end of its product life, dispose of it according to local 
ordinances. When any of the cardiograph accessories reach the end of their product life, 
dispose of these items in accordance with manufacturer instructions and local ordinances.
