Timer time
The One-Touch Timer function lets you quickly and easily set a
countdown timer. When the end of the countdown is reached, the alarm
sounds for 10 seconds and the graphic timer indicator flashes on the
display. To stop the alarm press any button. When the alarm stops, the
timer time is cleared automatically.
• You can set the One-Touch Timer time within the range of 1 to 60
minutes.
To use the One-Touch Timer
1. While in the Timekeeping Mode, hold down A until the display shows “1” (which indicates the Timer
Setting Mode).
• The timer is automatically set to one minute whenever you enter the Timer Setting Mode. The
countdown starts from one minute as soon as you release A.
2. Each time you press A again, the timer advances by one minute. Holding down A advances the
time at high speed. The countdown starts as soon as you release A.
• The hand indicator moves to indicate the timer time as it changes.
• Once the countdown starts (after you release A), the digital display automatically returns to the
Timekeeping Display. You can find out how much time remains by looking at the hand indicator.
• Whenever a timer operation is in progress, a hand rotates inside of the graphic timer indicator on
the display. This indicator remains on the display no matter what mode the watch is in.
Timer precautions
• Whenever a timer operation is in progress, pressing A does not switch between the time and date
display as it normally does. Instead, it changes the timer time.
• You cannot set the current time and date while a timer operation is in progress.
• The hand indicator is not meant to be a precise indicator, and so it may not align exactly with the
numbers on the scales. If the hand indicator does not align properly with "0" when a measurement
operation is complete, perform the adjustment procedure described for the Hand Setting Mode.
To clear the One-Touch Timer
1. While a One-Touch Timer operation is in progress, press A.
• At this time, the amount of time remaining appears on the digital display.
2. Keep pressing A until the timer changes to the current time or date display.
• As shown in the above illustration, the timer time advances up to 60, and then goes back down to
1, which is followed by the current time or date display.
