Countdown Timer
Dual timers can be set with two different starting times.
The watch can be configured so the two timers alternate,
so when one reaches the end of its countdown, the other
timer starts. You can specify a “number of repeats” value,
which controls how many times the two-timer countdown
operation is performed (1 = once, 2 = twice, etc.). The
starting time of each timer can be set in five-second steps
up to 99 minutes, 55 seconds.
You can specify up to 10 repeats. The watch emits a short
beep whenever either of the timers reaches the end of its
countdown during an ongoing timer operation. The watch
emits a 5-second beep when the end of the final timer
operation (specified by the number of repeats) is reached.
Countdown End Beeper
The countdown end beeper lets you know when the countdown reaches zero. The
beeper stops after about 5 seconds or when you press any button.

About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on, whenever you position
your wrist as described below in any mode. Note that this watch features a “Full Auto
EL Light”, so the auto light switch operates only when available light is below a certain
level. It does not turn on the backlight under bright light.
Moving the watch to a position that is parallel to the ground and then tilting it towards
you more than 40 degrees causes illumination to turn on.
• Wear the watch on the outside of your wrist.
