Abstract

In order to obviate the tendency for batteries to be changed at an overly early timing, the battery voltage is monitored and a first alarm is issued when the battery voltage drops below a predetermined level. The issuance of the first alarm sets a timer which times a predetermined period and issues a second alarm upon the expiration thereof. The length of the predetermined period may be adjusted by the user and the time from the issuance of the first alarm may be shown on a display upon demand.
