1. A fault monitoring method, comprising the steps of:
- providing a plurality of portable radio communication terminals in a commodity management system, each of which manages commodities by communicating with an inventory controller via a radio communication base station;
automatically executing a test of a radio communication section in arbitrary portable radio communication terminal when a number of retrying times of radio communication between the arbitrary portable radio communication terminal and said radio communication base station exceeds a predetermined number of times; and
displaying a fault of said radio communication section on a display section of the arbitrary portable radio communication terminal when said fault occurs and wherein a call time interval of retrying said radio communication between the arbitrary portable radio communication terminal and said radio communication base station is set longer than an average communication time of said radio communication between each of said portable radio communication terminals and said radio communication base station in said commodity management system.

Abstract
In a fault monitoring method for a portable radio communication terminal, plural portable radio communication terminals communicate with an inventory controller via a radio communication base station. In the portable radio communication terminal in a commodity management system, when the number of retrying times of radio communication between the portable radio communication terminal and the radio communication base station exceeds a predetermined number of times, the portable radio communication terminal automatically executes a test of a radio communication section and displays a fault on a display section of the portable radio communication terminal when a fault occurs.
