from the first usage.
Check the number of charging/discharging
times or the first usage date of the BTO-008
Lithium-Ion Battery Pack. The number of charging/discharging times should
not exceed 300 times, or usage duration should not
exceed one year.

Periodic Check Items and Procedures
Perform the periodic check according to the following list.

The periodic check should be performed once a year.

If the equipment fails any check items, the general judgment will be "Fail". Repair the equipment so that it
passes all the check items.

Use the equipment only if the judgments for all the items are "OK".

Check all cables, equipments, accessories, earth impedance, leakage current, and accuracy.
 Before the check procedure, back up the setup data and patient data on the USB memory
or SD card.
 Some models of commercially available bench top functional testers and patient simulators
can be used to verify the proper functionality of SpO
2
monitoring system, sensors, cables,
but they are incapable of properly evaluating the SpO
2
measurement accuracy. SpO
2
measurement accuracy can only be evaluated by comparing measurement data with SaO
2
measurements obtained from simultaneously sampled arterial blood using a laboratory Co-
oximeter.
