The explanation here is only for the particular point of Cal.VD59C Tweezers
1.REMARKS ON INSTALLING THE BATTERY
1) After the battery is replaced with a new one or after the
battery is reinstalled following the repairing procedures,
Be sure to touch the short-circuit the AC terminal of circuit
block and the switch spring with conductive tweezers
to reset the circuit as illustrated at right.
2) When the battery replaced with a new one, the time information stored in the built-in IC and
the time indicated by the stopwatch hands do not correspond with each other.
Reset the stopwatch hands to "0" position following the procedure below.
If the stopwatch hands should move improperly, also follow the same procedure.
