E-13
Display Illumination
In any mode, press the
F
button to illuminate the display for easy
reading in the dark.
You can specify 1.5 seconds or 3 seconds as the duration of display
illumination (page E-50).
Important!
•
The light may be difficult to see if you turn it on under bright sunlight.
•
If you press the
B
button or if an alarm operation starts while the
display is illuminated, illumination will turn off.
•
You may notice a slight sound from the watch while the face is
illuminated. This is the sound of EL panel vibration, and does not
indicate malfunction.
