PWR
Table 2 summarizes the PWR LED significance:
When the mains is not present, the PWR LED blinks at a 2-second
rate. The on/off state of the blink shows you how much power is
left in the battery. For example, as you can see in Table 2, if the
LED is lit for most of the two-second period (on 15/off 1), the bat-
tery is full. But if the LED is lit only briefly (on 1/off 15), the battery
is almost out of power.
Hermit Mode
In hermit mode (see also “Administrative Tasks at the System
Level” on page 17) only the USR, RUN, and PWR LEDs are signifi-
cant. Table 3 summarizes their significance.
