• Use the tap switch or button to switch the time
and calendar modes between three digital
displays. Set the time and calendar displays
according to their respective adjustment methods.
(1) How to switch the display by tap switch
(by tapping the watch gently)
• When the tap switch is on, tap the
face of the watch (the glass or
somewhere else) gently with your
fingernail to light the EL light and
switch display.
Do not tap on the glass with any sharp or
metallic object as these could scratch or break
the glass.
If the watch is strapped tightly to your wrist, it
may become difficult to switch the tap switch on.
For best results, adjust the strap to deep some
slack.
