Low battery warning
When the battery is almost empty, your radio warns you
in the following ways:
Q
The battery indicator on the radio display
looks empty.
Q
The status LED slowly flashes red.
Q
A high-pitched beep sounds.
You should recharge or replace the battery as soon
as possible.

discharge each time you use it.
