23 Batteries
23.1 Overview
The patient monitor is designed to operate on battery power during transport or whenever AC
power becomes interrupted. The battery is charged whenever the patient monitor is connected
to an AC power source regardless of whether or not the patient monitor is currently on.
Whenever the AC power is interrupted during patient monitoring, the patient monitor will
automatically run power from the internal batteries.
The patient monitor uses two battery packs. If the two batteries have very different charge
capacity, the message [Diff. Battery Voltages] is displayed. In this case, apply AC power to
the patient monitor until the two batteries have approximately equal charge capacity or are
both fully charged. You cannot use them before they have approximately equal charge
capacity or are fully charged.
On-screen battery symbols indicate the battery status as follows:
îš„
indicates that batteries work correctly. The solid portion represents the current
charge level of the batteries in proportion to its maximum charge level.
îš„ indicates that the batteries have low charge level and need to be charged.
îš„
indicates that the batteries are almost depleted and need to be charged
immediately.
îš„
indicates that no batteries are installed or only one battery is installed.
The capacity of the internal battery is limited. If the battery capacity is too low, a technical
alarm will be triggered and the [Battery Too Low] message displayed. At this moment, apply
AC power to the patient monitor. Otherwise, the patient monitor will power off automatically
before the battery is completely depleted.
NOTE
z Take out the battery before transport or storage to avoid damaging the battery.
WARNING
z Keep the battery out of children’s reach.
z Use only specified batteries.
