using condition
• Since this watch is energized by light, it should receive
light as much as possible. If the watch is placed near a
light source which generates heat (above 60°C / 140°F)
such as an incandescent lamp, a halogen lamp, etc., its
functions and parts may be deteriorated or deformed by
the heat. Accordingly, take care when applying light to it.
• It is important to check that the secondary battery is
charged normally (the customer knows that this watch is
a solar watch) and expain the correct charging method
to the customer.

current
• This watch uses the secondary battery block, instead of
consumption
a ordinary battery. Accordingly, prepare a silver battery
(1.55V) and measure the current consumption according
to the following procedure.
(1) Remove the secondary battery.
(2) Referring to Technical Manual, Basic Course, set the
silver battery (1.55V) to the adapter of the tester cor-
rectly.
(3) Pull the crown out.
(4) Set the tester.
(5) Return the crown to the normal position and measure
the current consumption of the movement.
Note:
When measuring the current consumption, do not
apply any light to the solar cell. If any light is applied,
the voltage changes and correct current consump-
tion cannot be measured.
