parent unit
Battery operation – charging
To ensure optimal safety, the parent unit is designed so that it can
only be operated with batteries inserted.
The battery must be charged for at least 12 hours before the device can be
first used independently of the mains; you may use the device during this
period. Whilst charging, the LED flashes red and green alternately. When the
battery is fully charged, the LED lights up orange.
If the parent unit battery is low the unit will beep twice and the LED will flash
red. If the device is not connected to a socket, it 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.
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 automati-
cally.
