If the counter is 0, the battery life notice is determined (step 16) and the process returns to step 8.

If the battery voltage detected in step 9 is the battery life warning voltage, it is determined whether a battery life warning has already been determined (step 10). If it is determined, the process returns to step 8; otherwise, the warning counter is decremented by one (step 11). If the counter is not 0, the process returns to step 8. If the counter is 0, the battery voltage warning is determined (step 12) and the process returns to step 8.
