PIP has a battery inside which stores the power to turn the wheels. It is a special type of battery that can be recharged so it can be used over and over again.
PIP has a special charger for its battery. Put PIP down on its back so that the charger socket underneath is easy to get at. The charger must be plugged into PIP's charger socket and then into the mains.
Make sure that PIP is switched off. When you turn the mains on, PIP will sing and bopbeep at you. The charger light next to the socket will come on.The charging light will go off when the battery is fully charged.
When PIP is being charged you can change its "personality". See advanced features.
PIP can be charged at any time. You do not have to wait until the battery is flat. You can leave PIP connected to the charger even when it is fully charged.
If you use PIP a lot you should try and charge it up whenever it is not in use. Even a short charge can help keep PIP going. It likes its "tea breaks" just as you do.
You should ensure that PIP's battery is charged every three months whether you have used it or not. Never store PIP with a flat battery.
