If the Date reed is broken or damaged, no amount of button-pushing or use of external magnets will accomplish anything. The correct test to see if the module is Auto-Set (in this case) is, push the Time button (we know that one works) three times quickly (within 1.5 seconds). If this is a 402 module, the display may simply stay on (and will stay on for 5 seconds if no other button is pushed), or go off for about a second, then come back on (this is far less common, and may be a chip made by another manufacturer, other than RCA, for Time Computer).
The Auto-Set feature was a big step forward for Time Computer; it allowed the user to do away with the difficult-to-handle, and easy-to-lose, setting magnets. All 403 DOW (Day-Of-Week), and 406 (24HR display) modules were Auto-Set. It became standard on all Pulsar models (except the Calculators) after its' introduction in late 1974 or early 1975; all Touch-Command modules also have the AS feature.
