■ LUMIBRITE WATCH
✼ 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, YK32, YK33,
YK34 & 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.

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.

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 be adversely affected by strong
magnetism. Keep it away from close contact
with magnetic objects.
• 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 a normal
temperature.
■ SERVICE
When your LORUS watch requires repair or
sevicing, please see the enclosed WARRANTY/
GUARANTEE.
