After the first time you connect the base
to the internet, it will search for an update
automatically.
You will see the lights coming on in sequence
from the bottom upwards.
When the update is being applied you will see
the lights flashing randomly before they all turn
off. This normally takes around five minutes
and once it is completed, you will be able to
make outgoing calls from your new phone.
Once the lights have come back on, your phone
will have updated and your service will be live.
