Powering On the Anesthesia System Operations
6 - 2 Operator’s Manual of Anesthesia System
WARNING: Before using the anesthesia system on the patient, ensure that the
system is correctly assembled and in good condition, and that all the
tests described in the Preoperative Tests are already completed. In case
of test failure, do not use the system. Contact a qualified Mindray
service representative to repair the system.
6.1 Powering On the Anesthesia System
1. Connect the pipelined gas supply and backup gas cylinders of the equipment.
2. Connect the power cord to the AC power source. Check that the AC power LED is illuminated.
3. Set the System switch to ON.
4. The Main Screen shows the start-up screen.
5. The alarm LED flashes red, yellow, and cyan once in turn and then a beep is given. This verifies
that audible and visual alarms are operational.
6. After several seconds, the system self-test screen is displayed and the equipment runs its system
self-test.
6.2 Powering Off the Anesthesia System
The system provides a powering off function with the following features:
• A prompt sound is given when user turns off the system. If the system switch is turned off
in Standby mode, the system waits 3 seconds to power off completely.
• If the power switch is turned off in Manual mode or in any of the Automatic ventilation
modes, the system will wait 12 seconds until it is completely powered off. In the 12-second
power off delay period, the screen will display a 10-second countdown timer. If the
equipment is performing Automatic ventilation, the ventilator will continue ventilating
the patient in the current ventilation mode.
• The system beeps once every second during the countdown from 10 seconds to 1 second.
When the timer turns to zero, a two-second power-off sound is played.
• When the user turns on the equipment during the power off delay period, the countdown
timer will disappear, and the anesthesia system will resume its previous state.
NOTE: The delayed power-off feature is not available when the equipment is
in the standby mode. The power-off feature is only available when the
equipment is in an active ventilation mode.
