For example, if one battery pack is installed, one battery icon appears. A fast blinking battery icon occurs: T when installing a new battery T during unknown battery status T when there is a problem with the battery. Similarly, read the percentages that appear next to the battery icons to find out exactly how much battery power is available. The battery percentage icon blinks under the following conditions: T when battery power is low, the number icon blinks. T if the battery has been in storage for a long period of time.
