The auto-repeat on and off status indicators in the graphic area are not
shown in the countdown alarm display screen. To check whether auto-
repeat is on or off, perform step 1 of the above procedure to change to
the setting screen. Then you can check the status of the graphic area to
see if auto-repeat is on or off. After you are finished, press A to return to

manually reset to the starting countdown time by pressing A.
Normally, an alarm tone sounds for 10 seconds when the end of the

or less, the alarm tone sounds for only one second.
