• Before maintenance (inspection, cleaning, disinfection), turn the
central monitor power off and disconnect the power cord from the
AC outlet. Otherwise the operator may receive electrical shock or the

• Do not disassemble or repair the central monitor. Disassembly and
repair must be performed by qualified service personnel.

• Software upgrade must only be done by qualified service personnel
or a person with technical knowledge. If upgrade is not done
correctly, the central monitor may freeze.

• Do the regular inspection according to the cycle specified by Nihon
Kohden. Otherwise, deterioration and loss of function are
overlooked and it results in incorrect monitoring.

• Restart the central monitor once every three months. Otherwise the
operation becomes unstable and monitoring may stop. During
restarting, patients monitored by the central monitor must be
monitored by another instrument.

• Replace the hard disk once every two years. If the hard disk gets
damaged, monitoring is incorrect and all data saved in the central
