2. Perform the electrical safety tests detailed in Safety Tests on page 27. If
the N-550 fails these electrical safety tests, refer to Troubleshooting on
page 43.
3. Inspect the fuses for proper value and rating (F1 and F2 = 2 amp,
250 volts).
Nellcor recommends replacing the N-550's battery every two years. When the
N-550 is going to be stored for two months or more, remove the battery prior
to storage. To replace or remove the battery, refer to Disassembly Guide on
page 55.
If the N-550 has been stored for more than 30 days, charge the battery as
described in Battery Charge on page 8. A fully discharged battery requires
11 hours with the N-550 in standby, or 12 hours if it is in use, to receive a full
charge. The battery is being charged whenever the N-550 is plugged into an
AC power source.
