When monitoring a patient, one Philips M4607A rechargeable Lithium Ion battery must always be
inserted into the battery compartment on the right side of the monitor. This applies even when you are
running the monitor from the external power supply. The battery seals the battery compartment,
thereby preventing the ingress of fluids or foreign bodies. A severe yellow INOP (!!INSERT
BATTERY) will be issued if the monitor is connected to AC mains without a battery fully inserted in
the battery compartment. This INOP will persist until a battery is loaded.
To use the monitor with battery power, disconnect the MSL cable (connecting the external power
supply) from the monitor.
You can switch between battery-powered and mains-powered (AC) operation without interrupting
The battery recharges automatically when the monitor is connected to the external power supply
