USING THE ALARM

The alarm can be set by following the same
procedure as that for the time/calendar adjustment.
Select the (flashing) display to be adjusted by
pressing the 

B

button in the alarm mode and set the

time when the alarm sounds by using the 

A

button.

* If the time/calendar mode employs the 12-hour
system for the hours display, the alarm set time is
also shown by the 12-hour system, so AM/PM
should be noted.

B. Switching the Alarm ON/OFF

The alarm can be switched ON/OFF by pressing the

A

button in the alarm mode. The alarm will sound

for 20 seconds. While the 

A

button is depressed,

the monitoring alarm sounds.

C. Stopping the Alarm Sound

Press any button to stop the alarm sound.

• The calendar can be set from 1994 to 2099
• The day of the week is automatically set when

the year, month and date are adjusted.

• If a non-existent date (for example, February

30) is set during adjustment, the time/calendar
display will show the 1st day of the month when
returned to the normal time/calendar mode.

• Because the auto-calendar is used, no

adjustment at the end of the month is needed.
