Japanese Patent JP3113558
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a radio communication equipment with a radio wave environment immune from noise into speech voice signal. SOLUTION: A control circuit 215 for a master set 42a in communication with a slave set 42b decides whether or not a measurement value of a reception electric field strength received at 1sec period keeps a reference level 1 or over for 5 seconds and decides whether or not a measurement value of a reception electric field strength received at 1sec period keeps a reference level 2 or less. When the measurement value of the reception electric field strength is less than the reference level 2 even once and the radio wave transmission power is set to a weak level, it is judged that there is a hindrance in communication by the weak radio wave transmission power and the control circuit 15 gives a command of the strong radio transmission power to a radio wave transmission power changeover circuit of a tuner 12 and the slave set 42b.
