The backlight uses an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark. An EL alarm feature can be turned on so the backlight flashes whenever an alarm or hourly time signal sounds.

Pressing [E] in any mode illuminates the display for about two seconds, regardless of the EL alarm on/off setting.

The backlight of this watch employs an electro-luminescent (EL) light, which loses its illuminating power after very long term use.

Frequent use of the backlight shortens the battery life.

The watch will emit an audible sound whenever the display is illuminated. It does not indicate malfunction of the watch.

The illumination provided by the backlight may be hard to see when viewed under direct sunlight.

The backlight automatically stops illuminating whenever an alarm sounds.

In the Timekeeping Mode, hold down [D] for about two seconds to toggle the EL alarm on (displayed) and off (not displayed).

The EL alarm on indicator remains on the display in all modes until you switch the EL alarm off.

The above operation controls operation of the EL alarm only. It does not affect operation of audible tones and signals.

You can set an alarm with hour, minutes, month, and day. When the alarm is on, the alarm sounds for 20 seconds at the preset time. When the Hourly Time Signal is on, the watch beeps every hour on the hour.

The types of alarm you get depends on the information you set:

Daily alarm: Set the hour and minutes for the alarm time. Set – for the month and – for the day. This type of setting causes the alarm to sound everyday at the time you set.

Date alarm: Set the month, day, hour and minutes for the alarm time. This type of setting causes the alarm to sound at the specific time, on the specific date you set.

1-Month alarm: Set the month, hour and minutes for the alarm time. Set – for the day. This type of setting causes the alarm to sound everyday at the time you set, only during the month you set.

Monthly alarm: Set the day, hour and minutes for the alarm time. Set – for the month. This type of setting causes the alarm to sound every month at the time you set, on the day you set.
