Anesthesia Gas Scavenging System (AGSS) connectors are at the rear of the A8/A9.
When the A8/A9 uses AC power supply, the A8/A9 power management system supplies power
for its main system while charging its internal battery. In case of an AC power failure, the A8/A9
operates on battery power. The main system switch can power on and off the system. The four
auxiliary AC sockets on the A8/A9 at the rear of the machine operate independent of the main
system switch.
The heater for the patient breathing circuit system does not operate when the
A8/A9 is working on battery power.
