ILLUMINATION
The display is illuminated while the
L
button is
depressed.
Electroluminescence refers to the emission
of light by a phosphorescent substance
under the influence of an applied voltage.
The panel of this watch provides illumination
by EL (electroluminescence).
Characteristics and replacement of the EL
(electroluminescence) panel
The EL (electroluminescence) panel has the
following properties.
• When the battery voltage drops, the brightness
(intensity) also drops.
• It is adversely affected by humidity.
If any water enters inside the watch by accident,
promptly request repair.
• The EL panel has a finite life span.
The brightness (intensity) gradually drops in
proportion to the total number of hours of use
(light emission).
If the display appears dark or is hard to see
when the EL panel is lit, ask either the store
where you purchased the product or your
nearest CITIZEN Service Center to replace the
EL panel. This repair will be done for a fee.
