Using the Batteries
One OR two Philips M4605A rechargeable Lithium
Ion batteries must be inserted into the battery
compartment at the rear of the monitor to use the
MP20/MP20Junior/MP30 monitor with battery
power.
You can switch between battery-powered and mains-
powered (AC) operation without interrupting
monitoring.
The batteries recharge automatically whenever the
monitor is connected to mains power.
Battery Indicators and Status
Information
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. An
estimate of the monitoring time available with the
current battery capacity is also shown. You can see the
actual capacity in the Battery Status window.
