23.3 Checking the Batteries
The performance of the rechargeable batteries may deteriorate over time. To check the
performance of the batteries, follow this procedure:
1. Disconnect the patient monitor from the patient and stop all monitoring and measuring
procedures.
2. Apply AC power to the patient monitor and allow the batteries to charge uninterruptedly
for above 6 hours.
3. Remove AC power and allow the patient monitor to run from the batteries until it shuts
off.
4. The operating time of the batteries reflects their performance directly.
If the operating time of the batteries is noticeably shorter than that stated in the specifications,
replace the batteries or contact your service personnel.
NOTE
z
Life expectancy of a battery depends on how frequent and how long it is used. For
a properly maintained and stored lithium-ion battery, its life expectancy is about 3
years. For more aggressive use models, life expectancy can be less. We recommend
replacing lithium-ion batteries every 3 years.

The operating time depends on the configuration and operation. For example,
monitoring NIBP repeatedly will also shorten the operating time of the batteries.
23.4 Installing the Batteries
The patient monitor uses two batteries. You can install the batteries by following this
procedure:
1. Turn off the patient monitor and disconnect the power cord and other cables.
2. Place the patient monitor with its back on the desk.
3. Open the battery compartment door.
4. Place the batteries into the slots per the “+” and “-” indications.
5. Close the battery door and place the patient monitor upright.
