(2) After the battery is replaced with a new one or after the
Tweezers
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.
(3) When the battery replaced with a new one, the time information stored in the built-in IC and the time
indicated by the dual time of 24 hour regulator , dual time of 12 hour regulator , and dual time of
60 minute regulator hands do not correspond with each other.
Reset the dual time of 24 hour regulator , dual time of 12 hour regulator , and dual time of 60 minute
regulator hands to "0" position following the procedure below.
If the dual time of 24 hour regulator , dual time of 12 hour regulator , and dual time of 60 minute
regulator hands should move improperly, also follow the same procedure.
Note
Refer to page 8 for each adjustment method.
