3.3.3 Power Saving Features

The oximeter enters the standby mode if the finger slips off the sensor, or the sensor

becomes disconnected from the oximeter. In the standby mode, if the sensor detects a finger,

the oximeter automatically resumes the normal operation mode; if no finger is detected within

5 minutes, the oximeter automatically shuts down.

3.4. Input/Output Communications

The oximeter meets the requirements of IEC60601-1 for short-circuit protection and leakage

current. The oximeter provides only one input/output interface, which connects either the

SpO

sensor or the communication cable.

3.4.1 Connecting the SpO

sensor

The interface is capable of connecting the 9-pin D connector used by the MINDRAY DS SpO

sensor adaptor. The interface is designed so that common DB9 connected cannot be plugged

in.

3.4.2 Connecting the communication cable

The interface is capable of connecting the Mindray DS serial communication cable, through

which the oximeter can be connected to a host computer for printing or upgrading. The

Mindray DS -designed communication software must be installed on the host computer

before the communication can be done. Common serial communication cable cannot be

connected to the interface.
