To operate the 3900/3900P oximeter effectively, you must
•
Know how the oximeter derives its readings (see Principles of operation in
chapter 1).
•
Be familiar with its controls and components (see chapter 1).
•
Understand its messages (see chapter 3).
Powering the oximeter
The 3900/3900P pulse oximeter is designed to operate on battery power and on all
commonly available voltage supplies. Your oximeter was shipped with the correct
power cord for your local AC power supply. Any hospital-grade power cord,
however, with the female connector end that fits into the power module (IEC-320
type) on the 3900/3900P can be used; the male connector that plugs into the
grounded “wall” outlet may be whatever is needed locally. The oximeter accepts a
range of AC mains power; see chapter 7 for details.
To protect data validity in cases of possible electromagnetic interference, make
sure the EMI line frequency mode switch is set to the same frequency as your
local AC power supply before using the unit for patient monitoring; see
EMI line
frequency under Mode switch settings later in this chapter.
A battery does not need to be installed for the oximeter to operate on the AC
power supply.
