FIELD: radio engineering, communication.
SUBSTANCE: portable unit (2) communicates a the base unit (1) according to DECT protocol. Furthermore, the portable unit (2) serves as a caller device that sends a call signal to a detector (3) attachable to an object according to a detecting protocol. Portable unit (2) transmits registration information to the base unit (1) via wireless communication initiated by registration completion by the detector (3) in one-to-one correspondence. In case when a request is received from a portable module (4), to be added as a calling device, the base unit (1) transmits the stored registration information received from the portable unit (2) to the portable unit (4). Portable unit (4) stores registration information received from the base unit (1).
EFFECT: simplification of added calling device and detector registration.
