Section 5 - Operation
Main Switch Panel
Testing the Battery
The backup battery system shall be tested daily. To test the battery:
1. Turn the SYSTEM POWER switch ON, and wait until the power-on
diagnostic screen is no longer displayed.
2. Remove the machine’s power plug from the electrical outlet.
3. Press and hold the BATTERY TEST button.
4. If the battery is sufficiently charged, the green BATTERY TEST light
illuminates after a short delay.
Usually, a fully charged battery can power the electrical components of
the anesthesia machine for at least 30 minutes in the event of a power
failure.
NOTE: During an AC power loss, the BATTERY LOW indicator is
illuminated when the battery reserve approaches depletion.
However, do not rely solely on this indicator for an
assessment of battery capacity. If the backup battery becomes
completely depleted and the machine does not have AC power,
the BATTERY LOW indicator light has no source of power and
does not function. Therefore, always remember to perform the
pre-use battery test.
To prevent premature battery failure, use backup battery
power only during interruption of primary AC power. Do not
start an anesthetic procedure on the anesthesia machine if the
AC POWER FAIL indicator light or the BATTERY LOW
indicator light is illuminated.
