2 seconds to turn it on. The battery icon indicates the battery status (see
the table below). The parent unit battery is fully charged after 12 hours of
continuous charging.

you need to charge the parent unit without interruption for at least
30 minutes to give the parent unit enough charge to use for a short time.
When operating in low battery condition, the parent unit displays Battery
low and . The light on the parent unit ashes and the parent unit
plays short beeps to alert you.
