The two button cells are used to power the clock and the calculator functions but not the display, which requires the AA battery or an AC adapter. The life of the button cells is stated to be about 1 year, but the AA battery will only illuminate the power-hungry VFD display for about 10 hours. However, the display can be extinguished by setting the MODE switch to "OFF", and then the time can be displayed by pressing the "TIME" button.
Alternatively, the clock can be displayed indefinitely using the AC adapter. To distinguish their calculators from the crowd, manufacturers started to add extra functionality beyond the normal calculator functions. Such is the case with the time mode of the Casio CQ-1.
By 1976 the electronics for calculator and time functions had shrunk to fit in a small hand-held calculator that could be powered for a year by two button cells. But the VFD display used in the CQ-1 was still very power hungry and limited the usefulness of this machine.
Treat yourself to a rare stunning vintage. Price is not set in stone - So please make an offer! Due to troubles in the past.
