Figure 4.2 Charging the batteries
The two internal batteries take approximately eight hours to charge.
They are charged individually, so each battery takes approximately 4
hours to charge.The internal batteries start charging whenever an
external power supply of greater than 15 V is detected.
Each 5700 receiver in your system is supplied with two internal
lithium-ion battery packs. To charge both sets of batteries, connect
both receivers to power supplies as shown in Figure 3.2.
