■ LUMIBRITE WATCH

(dial, hands, buttons, case, bezel,
strap, etc.)

✩ If your watch is a LORUS LUMIBRITE watch,

it has following features.

LORUS LUMIBRITE watches absorb and store
light energy from natural and artificial light
sources and emit light in the dark. They are
made of environmentally friendly material,
and therefore, are harmless to human beings
and the environment.

• With a full charge, LORUS LUMIBRITE

watches glow in the dark hours longer than
conventional luminous watches of this type.
If exposed to a light of more than 500 lux
(i.e., the brightness of a typical office) for
approximately 10 minutes, or direct sunlight
for 2 minutes, they will glow for hours.

• Since LORUS LUMIBRITE watches emit

the light they store, the brightness will
decrease gradually over time. The length
of time they will glow may also differ slightly
depending on such factors as the brightness
of and distance from the light source used
to charge the watch.

■ ILLUMINATING LIGHT

(for Cal. YK30, YK31, YK 32 & Z001)

When EL button is pressed and released in
the time/calendar or stopwatch display, or
in the alarm setting or time/calendar setting
function, the electroluminescent light evenly
illuminates the display for 4 seconds for
easy viewing in the dark.

12-hour

[Keeping button “C” pressed]

* When the “A” (AM)/“P” (PM) mark disap-

pears, the calendar or the alarm display is
shown in the 24-hour indication.

EL button

Notes:

1. The watch works with one battery. When

the light begins to lose its luminance,
this is an indication that the battery is
depleted. We recommend that you change
the battery before the watch itself stops.

2. If the light is used continuously for a

long time, the battery life may be less
than the specified period.

■ BATTERY CHANGE

The miniature battery which powers your watch
should last as individually specified below.
However, because it is inserted at the factory,
the actual life of the battery once in your
possession may be less than the specified
period. Be sure to replace the battery to
prevent any possible malfunction as soon as
it runs down. To replace the battery, we
recommend taking the watch to a local watch
repair shop.

CAUTION

Do not expose the old battery to
fire or recharge it. Keep it at a
place beyond the reach of chil­dren. If a child swallows it, consult
a doctor immediately.

* If your watch is 200 M/20 BAR, 100 M/10

BAR or 50 M/5 BAR water resistant, it is so
indicated on the dial/case back.

• Do not operate the buttons when the watch
is wet.

• If the watch is exposed to salt water, rinse
it in fresh water and then wipe it thoroughly
dry.

Caution:

Leather straps are not water resistant except
so indicated, even if the watch head is water
resistant.

• ALLERGIC REACTION

Because the case and band touch the skin
directly, it is important to clean them
regularly. If not, shirt sleeves may be
stained and those with delicate skin may
develop a rash. Please wear the watch
with some play to avoid any possible allergic
reaction. If you develop a rash on your
wrist, stop wearing and consult a physician.

• MAGNETISM

Your watch will not be affected by mag­netism generated by household electric
appliances.

• SHOCKS AND VIBRATIONS

Your watch may be worn for normal sports
activities, but be careful not to drop it or
hit it on hard surfaces.

• TEMPERATURE

Your watch is preadjusted so that constant
accuracy may be insured at normal tem­perature.

Note: If the alarm is used for more than 30

seconds a day (and/or the illuminating
light for more than 4 seconds a day
for Cal. YK30, YK31, YK32 & Z001),
the battery life may be less than the
specified period.

■ SERVICE

When your LORUS watch requires repair
or servicing, please see the enclosed
WARRANTY/GUARANTEE.
