The explanation here is only for the particular point of Cal VD37&VD38
1 REMARKS ON INSTALLING THE BATTERY
(1) Battery
・
How to install the battery
Remove the hook of the switch springs battery clamp portion
Insert the battery sideways, and have the hook of the switch springs battery clamp portion catch
the main plate
Battery clamp position
Hook Main plate
Hook
(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
