2.3 Parent unit installation
The package comes with two rechargeable batteries. You can power up the parent
unit by using two rechargeable batteries or by connecting it to the mains power.
However, even if the parent unit is connected to the mains power, we recommend
you to also install the rechargeble batteries. This guarantees the continual operation
in case of a power outage.
To set up the parent unit:
1.Remove the battery compartment cover.
2.Install the supplied rechargeable batteries into the battery compartment, matching
the polarity markings (+ and -).
3.Replace the battery compartment cover.
4.Insert the DC plug of the other power adapter into the DC socket on the side of the
parent unit.
5.Connect the other end of the power adapter to a suitable mains power socket.
6.The Charging LED lights up indicating the parent unit is charging.
