Abstract

PROBLEM TO BE SOLVED: To obtain a method for protecting a portable telephone from an abnormal temperature and its device in order to protect a portable telephone from a high temperature, when left inside a car especially in midsummer. SOLUTION: A temperature detecting circuit 25 detects a portable telephone's environment temperature, the information of which is sent to a temperature examining circuit 60 by serial signals to determine whether or not the detected temperature remains within a given range (ex. 60 deg.C or below). In the case of a deviation from the range, a cooler controlling circuit 61 starts a car air conditioner 70 to adjust the environment temperature. This makes it possible to protect the portable telephone from abnormal temperature without the presence of a user.
