When a switch 12 is turned on, the electric power is supplied from a lithium battery 4 to a liquid crystal television device 10 and at the same time, an inverter 8 converts the DC voltage from the lithium battery 4 to an AC voltage of 100 V and supplies it to the digital CS/BS tuner 6. Therefore, the direction of the parabolic antenna 24 can be adjusted over a look at information displayed on the liquid crystal television device 10 by the antenna reception level checking function of the digital CS/BS tuner 6.
