parent unit
Battery operation – charging
The battery must be charged for at least 10 hours before the device
can be first used independently of the mains; you may use the de-
vice during this period. Whilst charging, the power LED flashes red.
As soon as the battery is fully charged, the LED glows green.
If the baby unit is used independently of the mains, the power LED
begins to flicker when the battery is low. Moreover, a beep sounds
as a warning on the parent unit every 4 seconds.
When the battery in the parent unit is low, the unit's power LED
flashes and the unit beeps every 4 seconds. If the devices are not
connected to a socket, they will switch off automatically after a short
period.
If the devices are operated using the power supply unit and there is
a power cut, the parent unit switches to battery operation. For this
reason, the standby time is dependent on the battery charge status.
If no batteries were inserted in the baby unit, it switches off
in the event of a power cut and there is an acoustic warning
on parent unit.
discharging the parent unit
The battery should be discharged after being charged 300
times. To do so, leave the unit switched on until it switches
itself off automatically.
