Abstract
A cordless telephone handset that does not affect the use of a magnetic pick-up type hearing aid. The cordless telephone handset includes a TDD processing section for controlling transmission and reception by means of TDD communications, and a suppressing device for suppressing variations in the magnetic field generated by the TDD processing section. By suppressing variations in the magnetic field generated by the TDD processing section, the problem of magnetic field variations being picked up by a magnetic pick-up type hearing aid and being output as noise, is overcome.
