4. ECG Monitoring

When the transmitter is used without the SpO

probe (sensor), it will measure

only ECG and respiration.

C A U T I O N

When using the transmitter with only the ECG lead cable, SpO

measurements on the receiving monitor shall be turned off to prevent an
erroneous alarm.

Connecting the ECG Lead Cable and Electrodes

The optional ECG lead cables for LX-7230N are as follows.
