Charging Status LEDs
On the drop-in charger, the radio and battery charging pockets have their own LEDs.
On the MUC, each of the 6 charging pockets has an LED. The LEDs are grouped into
pairs to show which charging pockets are paired (for cloning, see page 32).
The LED is solid red when the battery is charging, and solid green when charging is
complete.
Battery Meter
The battery meter in the upper left corner of the display (see page 20) shows how
much battery power is remaining.
