A7™ Operating Instructions 046-004667-00 1 - 7
Product Description General System Overview
NOTE: The operating time of a battery depends on equipment configuration
and operation.
NOTE: In case of battery failure, contact Mindray service personnel for battery
supply replacement.
CAUTION: Please replace your battery when it reaches the end of its service life.
Failure to replace the battery may cause serious damage to your device
from battery overheating.
The A7 Anesthesia System is designed to operate on battery power whenever AC power is
interrupted. When the A7 is connected to an AC power source, the battery supply is charged whether
or not the A7 is turned on. In case of power failure, the A7 will automatically switch to run from the
internal battery supply. When AC power source is restored within the specified time, the battery
supply begins recharging, and power is switched from battery to AC automatically to ensure
continuous system use.
When power is lost for less than or equal to 60 s, the alarm settings prior to the power loss will be
restored automatically.
The on-screen battery symbol indicates the battery status (see FIGURE 1-1).
