Claims

[Claims for Utility Model Registration] A first low-power radio unit, a first weak-power radio unit, a first reception level determination unit that determines the level of radio waves received from a slave unit, and the first radio unit. a base unit having a first control section that selectively switches a low power radio section and a first weak power radio section into an active state; a second low power radio section; selectively activating the second low-power radio unit, the second low-power radio unit, and the second low-power radio unit that determines the level of the radio wave received from the base unit. a slave unit having a second control unit that switches the state, and each of the first and second control units is configured such that each reception level determined by the first and second reception level determination units is both at a reference level. In the above case, actively controlling the first and second weak radio units,
A cordless telephone set, characterized in that the first and second low-power radio units are configured to be actively controlled when at least one of the received wave levels is below a reference level.
