3.3 Performance Tests
The battery charge and battery performance test should be performed before monitor
repairs whenever the battery is suspected as being a source of the problems. All other
tests may be used following repairs or during routine maintenance (if required by your
local institution). Before performing the battery performance test, ensure that the battery
is fully charged. This section is written using Nellcor factory-set power-up defaults. If
your institution has preconfigured custom defaults, those values will be displayed.
3.3.1 Battery Charge
1. Connect monitor to AC power source using proper power cord.
2. Verify AC Power indicator is lit.
3. Charge battery fully for at least 18 hours.
4. The only way to check for a full charge is to perform the procedure in paragraph
3.3.2 “Battery Performance Test.”
Note: The battery may require a complete charge/discharge cycle to restore its normal
capacity, depending on its previous usage.
3.3.2 Battery Performance Test
1. The N5500 monitor is specified to typically operate on battery power a minimum of
1 hour, at 25°C, with no printing, and one NIBP measurement every 5 minutes.
Before performing this test, ensure that the battery is fully charged (paragraph 3.3.1).
2. Ensure monitor is not connected to AC power.
3. With N5500 turned off, press Power On/Off switch and verify battery icon appears at
bottom of display after power-on self-test is completed. Boxes in battery icon should
all be filled, indicating battery is charged.
