Batteries
23.1 Overview
This monitor is designed to operate on rechargeable Lithium-ion battery power during
intra-hospital patient transfer or whenever the power supply is interrupted. The battery is
charged automatically when the monitor is connected to AC power, no matter the monitor is
powered on or not. Whenever the AC power is interrupted during patient monitoring, the
patient monitor will automatically run power from the internal batteries.
On-screen battery symbols indicate the battery status as follows:
„
Indicates that the battery works correctly. The solid portion represents the
current charge level of the battery in proportion to its maximum charge level.
„
Indicates that the battery has low charge level and needs to be charged. In
this case, the patient monitor provides an alarm message.
„
Indicates that the battery is almost depleted and needs to be charged
immediately. Otherwise, the patient monitor shuts down automatically.
„
Indicates that no battery is installed.
The capacity of the internal battery is limited. If the battery charge is too low, a technical
alarm will be triggered and the message [] or [] 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.
23.2 Battery Guidelines
Life expectancy of a battery depends on how frequent and how long it is used. For a
properly maintained and stored lithium ion battery, its life expectancy is about 3 years. For
more aggressive use models, life expectancy can be less. We recommend replacing lithium
ion batteries every 3 years.
To get the most out of the battery, observe the following guidelines:
„
The battery performance test must be performed every two years, before monitor
repairs, or whenever the battery is suspected as being the source of the problems.
„
Condition a battery once when it is used or stored for 3 months, or when its operating
time becomes noticeably shorter.
„
Take out the battery before the monitor is transported or will not be used for more than
3 months.
