External Power Supply M8023A
The external power supply M8023A (option #E25) allows you to operate the fetal monitor from an
AC (alternating current) power source of 100 V to 240 V (± 10%) and 50/60 Hz (± 5%). If this option
is used, then the M8023A (option #E25) power supply is included for FM20/30.
WARNING
• Always use the supplied power cord with the earthed mains plug to connect the external power
supply M8023A (option #E25) to an earthed AC mains socket. Never adapt the mains plug from
the power supply to fit an unearthed AC mains socket.
• Do not use AC mains extension cords or multiple portable socket-outlets. If a multiple portable
socket-outlet without an approved isolation transformer is used, the interruption of its protective
earthing may result in enclosure leakage currents equal to the sum of the individual earth leakage
currents, so exceeding allowable limits.
• Do not connect any devices that are not supported as part of a system.
• Any non-medical device placed and operated in the patient’s vicinity must be powered via an
approved isolation transformer that ensures mechanical fixing of the power cords and covering of
any unused power outlets.
Battery Power Indicators
The battery LED and battery status information on the Main Screen, in combination with INOP
messages and prompts, help you keep track of the battery power status. The indicators always show
the remaining capacity in relation to the battery's actual maximum capacity, which may lessen as the
battery ages. You can see the actual capacity in the
Battery Status
window.
