Figure 1-1. Charging Methods
To charge a Detector or the Display directly from mains power, connect the ac-power
adapter directly to the ac adapter connector on a Detector or the Display. To charge a
Detector and the Display simultaneously, connect the ac adapter to the ac adapter
connection on the Display and then, using the Mini-B to Type-A USB cable, connect the
Detector to the Display.
Note
See the markings on the ends of the cable to identify the Mini-A and Mini-B
ends.
A Detector or Display battery can also be charged through a USB connector on a PC.
Connect the Display or Detector to a PC USB port using the Mini-A to Type-A USB
cable.
Both Detectors and the Display have a battery-status indicator to indicate the condition of
the internal battery. The indicator is a tri-color LED that shows the level of charge on the
internal battery. Table 1-5 explains the battery-status indicator levels.
