The PT2000 and TopGun run on two types of batteries. The main batteries supply operating
power for the PT2000 unit and for the TopGun module or another input device. The internal
lithium battery provides backup power to maintain the random-access memory and real-time
clock when the main batteries are removed.
The portable can use two different types of main batteries: individual alkaline cells or a
rechargeable nickel-cadmium (NiCd) battery pack.
