12.5 Replacement of Batteries
Both the GDC Board inside the display unit and the memory cards
use a battery to store information. The life of these batteries is about
three years. When the voltage of a battery is low, the “battery” icon
appears on the display. The offending battery should be replaced at
your earliest convenience, so that important information will not be
lost.
