•Pressing Dto perform a lap/split time operation freezes the lap/split time at that point on the display for about eight seconds. After that, the display returns to normal stopwatch time measurement.
•During a stopwatch time measurement operation, the upper part of the display shows the hour digit and the current lap/split number, the center part shows the current split time, and the lower part shows the current lap time.
•When the pacer signal is turned on, it sounds for the first 30 seconds after you start
a stopwatch time measurement operation. After that, the pacer signal sounds for 30 seconds whenever you press B.
•If the pacer signal does not sound even though you have it turned on, press Bto change the positions of the lap time and split time on the display. This should cause the pacer signal to sound.

The following shows how you can control the position of the lap time and split time on
the stopwatch screen.

Basic Data
The term “basic data” refers to the pacer signal setup, and information about your stride length.

How the Stopwatch Works
There are two ways you can use the stopwatch: to measure elapsed time and lap/split times like a standard stopwatch (see “To measure times with the stopwatch”), and to keep track of the distance you cover while jogging or running. In order to use the stopwatch to keep track of distance, you must first perform the steps listed below.
1.Set your basic data. See “Basic Data”.
2.Turn on the pacer signal. See “To turn the pacer signal on and off”.
Note
•In order to obtain accurate distance calculations, you must set accurate basic data and keep your exercise pace in accordance with the pacer signal emitted by the watch.
•Use the Recall Mode to view data stored in memory.
•You can view distance covered data only by recalling it in the Recall Mode. It does not appear on the Stopwatch Mode screen.
•You cannot change basic data settings while a Stopwatch Mode time measurement operation is in progress. Stopwatch operation must be stopped and the Stopwatch screen must be cleared to all zeros before you can change basic data settings.
•Whenever you want to change the stride length unit, you must first reset the Cumulative Total screen to zero.
•Be sure to update basic data values whenever the person using the watch changes.
Pacer Signal
The pacer signal of this watch beeps in accordance with a pacer value (rate) set by you. You can use the pacer signal to maintain a constant pace while jogging or running. You can also turn off the pacer signal when you do not want to use it.
•The pacer value you set specifies the number of beeps per minute.
•Turning on the pacer signal causes the watch to beep at the rate specified by the pacer value.
•You can set a pacer value in the range of 100 to 200 beats per minute, in units of 5.
•You can disable the pacer function by setting a pacer value of xxx. While the pacer value is set to xxx, the watch does not calculate distance covered.
Stride Length
You can specify either centimeters (XM) or inches (Yn) as the stride length unit. The unit you specify for the stride length unit also determines the unit of measurement used for the distance value in the Stopwatch Mode and Recall Mode, as shown below.
