Using the Menu Screens
Many of the operations of this watch are performed using on-screen menus.
The following describes the general procedures for using on-screen menus.
To use the Menu Screens
• In any mode, press the MENU button to
display the Menu Screen.
• The highlighted menu item is the one that
is currently selected.
• Use L and K to move the highlighting.
The menu will scroll automatically if all the
items do not fit on a single screen.
• Press ● to select the highlighted menu item. Selecting a menu item
sometimes displays another menu, and sometimes it displays some sort of
Setting Screen.
• Press the MENU button to back track through menus.
Adjusting Display Contrast
Use the following procedure to adjust the relative darkness of the figures on
the display.
To adjust display contrast
1. In any mode, press the MENU button
and the H button at the same time to
display the Contrast Screen.
2. Use K to increase contrast (making the
screen darker) and L to decrease it.
• You can set contrast to one of 16 levels.
• The current contrast setting is indicated
by a value on the Contrast Screen.
3. After the contrast is the way you want, press MENU or ● to return to the
screen you started from in step 1.
• You can also display the Contrast Screen using the following procedure:
Press MENU, highlight SET UP, press ●, highlight CONTRAST, press ●.
After setting the contrast, press MENU twice to return to the Menu Screen.
BACKLIGHT
Press the LIGHT button to illuminate the
display for about two seconds.
• The backlight is disabled while a GPS
measurement operation is in progress
(indicated when the GPS indicator is
flashing) and while the WAIT message is
on the display following a Set Up Menu
operation.
• The electro-luminescent (EL) panel that
illuminates the display loses illuminating
power after very long use.
• Illumination may be hard to see when
viewed under direct sunlight.
• The watch may emit an audible sound
while the backlight is on. This is normal
and does not indicate malfunction.

Screen and return to the screen you started from in step 1.
Notes
• The year can be set in the range of 1995 to 2039.
• The day of the week is displayed automatically in accordance with the
month and day settings.
• The watch's built-in full automatic calendar makes allowances for different
month lengths and leap years. Once you set the date, there should be no
reason to change it except after replacing the watch’s battery.
• The summer time or Daylight Saving Time (DST) Screen automatically
advances the current time setting by one hour. This is a practice followed
in certain geographic areas, and may or may not apply in your area.
Setting the Current Time and Date
Use the Menu Screen to set the current time and date, and to reset the
second’s count to zero.

current positions of satellites. Make sure that your time and date setting are
always accurate.
