Abstract

PROBLEM TO BE SOLVED: To clearly recognize remaining quantity of a batter that the user must leave as a minimum in the basic call function by stopping an additional function when the remaining quantity of the battery comes to a specified value or under. SOLUTION: A power voltage detector 107 monitors the output voltage of a battery 106 at all times, and indicates the remaining quantity of a battery in a display 108. Furthermore, if the user uses a call function or a music playback function, the remaining quantity of a battery 106 decreases, and when it becomes a prescribed voltage value or under, a main controller 111 informs the user of the effect that the music playback function stops by a desired warning sound through a speaker 102. As a result, when the battery comes to a remaining quantity required for the basic call function, this devices stops the operation of additionals function other than it, so this can ensure call function, and the user can easily confirm that the remaining quantity of a battery for only the call function is left.

When the indicator 401 indicating the remaining battery level for a call is displayed in full, it is assumed that the remaining battery level is such that a call for a predetermined time is guaranteed. At the same time, the main control unit 111 notifies the user of the stop of the music playback function via the speaker 102 with a desired warning sound, and stops the music playback after a predetermined time. still,
The warning sound may be a buzzer sound or predetermined music. Thus, the user can know that the music reproduction function is stopped without looking at the display 108.

If the user wants to play even after the warning 402 is displayed after the indicator 402 of the remaining battery for music playback as the second battery is not displayed, the music is played back through the key input unit 105. It is assumed that music playback is continued by inputting a signal indicating a continuation instruction.

As described above, in the present embodiment, the musical notation is used for the indicator display (see 202 in FIG. 2) of the remaining battery level in the portion where the music reproduction function can be used, but other display forms may be used. A display form that is easy for the user to visually recognize according to the function may be used. For example, an indicator display of the remaining battery level in a portion where the call function can be used (FIG. 2)
May be used as the phone display symbol.

[0035]

According to the present invention, when the remaining battery power is less than the basic function, the operation of the additional functions is stopped, so that the communication function is secured.

When the remaining battery level is lower than the battery capacity required for the call function, which is a basic function, a warning sound is issued so that the user can easily recognize that only the remaining battery capacity for the call function is left. it can.

When the remaining battery power is below the level required for the basic call function, a warning sound is issued and the operation of the additional function is stopped after a predetermined time. Can stop the additional function, and can eliminate the discomfort of the user due to sudden stop of the additional function without notice.
