Battery malfunction symbols: 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
