When the battery pack indicator
changes from green to red, the unit
emits a 1-second warning beep.

When both battery packs are low or not
installed, the unit enters a power-down
warning period. During this period, both
battery LEDs blink red, and the unit
emits a series of 3 warning beeps of 1
second each followed by 10 seconds of
silence. This sequence is repeated 4
times. If either battery is replaced during
the warning period with a charged
battery pack, the
new battery pack’s
status changes to green and the power-
down warning ceases. The power-down
warning also ceases if an external power
source is connected at this time.
