Question
Why doesn't battery
check light on the parent
unit light up when I start
to recharge the parent
unit.
Answer
The microphone sensitivity level of the baby unit may be set too
high, which causes the parent unit to consume a lot of energy.
Decrease the microphone sensitivity level with the SENSITIVITY
button on the parent unit.
It may take a few minutes before the battery check light lights up
when you charge the parent unit for the first time or after a long
period of disuse.
