GUIDANCE AND MANUFACTURER’S DECLARATION  ELECTROMAGNETIC IMMUNITY
The WW1020/WW1000 pulse oximeter is intended for use in the electromagnetic environment
specied below. The customer or end user of the WW1020/WW1000 pulse oximeter should
ensure that it is used in such an environment.

continued operation during
power mains interruptions,
it is recommended that the
WW1020/WW1000 pulse
oximeter be powered from
an uninterruptible power
supply or a battery.
