A portable terminal device comprises an antenna for receiving radio waves
from a base station, an incoming call alarm for notifying the user of the
reception of radio waves, a control circuit provided between the antenna
and the alarm for activating the alarm and a memory. The memory is
capable of storing therein a predetermined incoming call rejecting
condition or incoming call notifying condition via the control circuit.
The control circuit includes comparison means for detecting whether one
of information as to the current time and date, information as to the
self-location of the device and information as to the caller or the
combination of these items of information is in match with the incoming
call rejecting condition or incoming call notifying condition stored in
the memory. The control circuit has the function of changing over to
predetermined incoming call rejecting means or incoming call notifying
means when a match is obtained.
