Illumination
This watch has an EL (electro-luminescent) panel that causes the entire display to

the display), press B to turn on illumination for about one second.
Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after very long
use.
• Illumination may be hard to see when viewed under direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
Auto Return Feature
• If you leave the watch in the Alarm Mode for two or three minutes without performing
any operation, it will change to the Timekeeping Mode automatically.
• If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch will exit the setting screen
automatically.
Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation will scroll at high speed.
