Battery Power Indicators
Battery status/malfunction indicator: Normal battery function is indicated by the battery power
gauge, together with the remaining operating time, on the Main Screen. You are informed of problems
or changes in the status of the battery by the battery status/malfunction indicator. This consists of a
blank battery gauge containing a symbol. If the symbol is red, this indicates a critical situation. You can
check the specific cause of the problem by looking at the symbol(s) displayed in the Battery
Status window (see page 219).

Monitoring Time Available: While the monitor is running on battery power, a time is displayed
below the battery power gauge. No time is displayed when the monitor is running on AC mains power
via the external power supply (M8023A). This is the estimated monitoring time available with the
current battery power. Note that this time fluctuates depending on the system load (the display
brightness and how many measurements you carry out), the age of the battery, and the remaining
capacity of the battery.
