CONSTITUTION:The transmitter arranged to the television receiver is stored in a case 1, on the front of which a power source switch 2, a transmission output adjusting variable resistor 3, and an LED level display device 4 are provided, and sound signal input terminal and channel changeover switch or the like (not shown) are provided on the rear face. The transmission output adjusting variable resistor 3 adjusts the transmission output independently of the position of the sound adjustment of the receiver and a proper transmission output is obtained thereby. On the other hand, the receiver is stored in a small sized case 20 which is of portable type and a sound adjusting variable resistor 23, a channel changeover switch 22 and an earphone output terminal are provided thereto. A battery is used as a power source. |
