Mindray A9 - Cautions; Notes

6-2
6.2.2 Cautions
CAUTION
 Refer to the maintenance period in Chapter 4 Device Maintenance when
conducting periodic maintenance.
 If the pipeline gas supply is in use and the main switch of the system is set to the
ON position, ensure that the standby gas cylinder valve is not opened. Otherwise,
the cylinder gas supply could be depleted, resulting in an insufficient reserve in
the case of a pipeline gas supply failure.
 Use the cleaning agent sparingly. Excess fluid could enter the machine, causing
damage.
 The machine can be operated only by trained and skilled medical personnel.
6.2.3 Notes
NOTE
 Only a bacterial filter with a low-flow resistance can be connected to the patient
module and/or patient pipe.
 Wear surgical gloves when touching or disassembling valves or other internal
components of the breathing system.

Ensure that the gas supply of the machine always complies with technical
specifications.
 The markers on the APL valve and PAW gauge are for reference only. The
anesthesia machine displays the calibrated airway pressure.
 If the machine malfunctions during initial calibration or testing, do not use it
until the fault is rectified by a professional service technician.
 After servicing, functional tests, sensor tests, and system tests must be carried
out prior to clinical application.

The anesthesia machine supports up to two vertical mounting brackets to
accommodate additional monitors and other devices. Unauthorized mounting
accessories are not recommended.
 Ensure that all devices on the top plate of the anesthesia machine are secured.
