■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
B
Cal. Y717, Y718 and Y719
Press button “B” in any mode. The light
illuminates the display for 4 seconds for
easy viewing in the dark.
Cal. Y737
Press button “B” in any mode. The
electroluminescent light evenly illuminates
the display for 4 seconds for easy viewing in
the dark.
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.
■ViViDiGi
ViViDiGi is a new type of liquid crystal panel
that makes possible various colors and high
contrast.
• Excellent light reflection and transmission
make the display bright and clear.
• Various color options are available.
• Either the whole panel or the displayed
data only can be illuminated.
* Features vary in different models.
■BATTERY CHANGE
Theminiaturebattery SEIKOCR2025or Matsushita
CR2025, which powers your watch should last
approximately 3 years. However, because it
is inserted at the factory, the actual life of
the battery once in your possession may be
less than 3 years.
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.
Note:
If the illuminating light is used for more than
4 seconds a day, the alarm more than 20
seconds a day and/or the timer warning sound
more than 20 seconds a day, the battery life
may be less than the specified period.
■CARE OF YOUR LORUS WATCH
CAUTION
Do not expose the old battery to
fire or recharge it. Keep it at a
place beyond the reach of chil-
dren. 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 mag-
netism 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 tem-
perature.
■SERVICE
When your LORUS watch requires repair or
servicing, please see the enclosed
WARRANTY/GUARANTEE.
