PURPOSE:To attain miniaturization, low power consumption, low cost and to increase the transmission output by constituting the titled equipment by a radio equipment main body, a battery pack and an on-vehicle adaptor. CONSTITUTION:The titled equipment consists of a radio equipment main body 1 having a built-in antenna 4, a battery pack 2 of external mount and an on- vehicle adaptor 3. In mounting the battery packs 2 to the radio equipment main body 1, power terminals 7, 15 of both are connected and the equipment 1 is used as a portable radio equipment. On the other hand, in mounting the radio equipment main body 1 to the on-vehicle adaptor 3, the power terminals 7, 24 and coaxial connectors 8, 25 for high frequency signal supply are con nected, and the equipment is used as an on-vehicle radio equipment. Thus, at least a changeover switch for power changeover is eliminated, then the trans mission output is improved, and low cost, miniaturization and low power con sumption are attained. |
