1. A remote control system comprising:
- a remote commander with a central processing unit and a battery mount detection means connected to said central processing unit;
a non-volatile memory connected to the central processing unit;
an electronic device main unit; and
infra-red, bi-directional data link means;
said infra-red, bi-directional data link means adapted to allow communication between said remote commander and said electronic device main unit and including a user operable transmitter and a receiver in said remote commander and an automatic transmitter and a receiver in said electronic device main unit;
wherein when a user operates said user operable transmitter, said remote commander transmits via said infra-red, bi-directional data link means at least one command signal selected from a group of command signals which is received by said receiver in said electronic device main unit for controlling the operation of the electronic device main unit, and said automatic transmitter in said electronic device main unit transmits a status signal via the infra-red, bi-directional data link means, the status signal received by said receiver in said remote commander to indicate an operating status of said electronic device main unit, said remote commander including a display controlled by said central processing unit for indicating the operating status of said electronic device main unit for permitting the user to determine the operation status of the electronic device main unit,wherein said remote commander is battery powered, wherein said battery mount detection means signals the central processing unit with a battery present signal regarding the presence of a battery mounted in said remote commander, and wherein said central processing unit stores a previously received battery present signal or a signal indicative of a battery absent condition in the non-volatile memory as a preceding battery mount condition signal; and
whereby the central processing unit determines if the non-volatile memory contains a battery present signal or a signal indicative of a battery absent condition as the preceding battery mount condition signal and the central processing unit prevents the transmission of selected command signals chosen from said group of command signals from the remote commander to the electronic device main unit when the central processing unit determines that the signal indicative of a battery absent condition was stored in the non-volatile memory as the preceding battery mount condition signal and the currently received signal is a battery present signal.

Abstract
A remote control system comprising a remote commander and an electronic device main unit, in which the remote commander transmits a command signal to the electronic device main unit, the electronic device main unit receives the command signal, and the electronic device main unit transmits a signal that represents a setting state of the electronic device main unit. The remote commander receives the signal from the main unit and the remote commander displays the setting state of the electronic device main unit so that it can be checked by the user.
