Electronic apparatus with remote controller

An electronic apparatus with a remote controller, the remote controller including power supply means constituted by a battery, remote manipulation means that transmits an instruction signal corresponding to an instruction entered through manipulation of a manipulation key, thereby remotely manipulating the electronic apparatus, detection means that detects the voltage of the battery, and transmission means that converts the detected battery voltage into a code value and transmits the code value, wherein the transmission means converts the detected battery voltage into a code value, which is assigned to a classified level of voltage value of the detected battery voltage, and the electronic apparatus comprises code value converting means that converts the code value transmitted from the remote controller into a corresponding residual battery capacity value and residual battery capacity informing means that indicates the residual battery capacity converted from the code value by the code value converting means.
