User-supplied car batteries can be used as a backup power supply in the event of a power
failure. In case of a power failure, the batteries automatically maintain power to the main unit.
The optional Battery Adaptor (KX-A46) is required.
The Battery Adaptor should not be exposed to direct sunlight. Keep the adaptor and car
batteries away from heating appliances and fire. Place car batteries in a well ventilated place.
Connection
When connecting the battery adaptor, keep the following in mind.
• Check the polarities of batteries and wires.
• Make sure that you do not short the batteries and wires.
