Operation Guide 5535
Note
Resetting the seconds to 00 while the current count is in the range of 30 to
59 causes the minutes to be increased by 1.
The watch's built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to
change it except after you have the watch's battery replaced.
The day of the week changes automatically when the date changes.
While the 12-hour format is selected for timekeeping, a P (PM) indicator will appear
for times from noon to 11:59 p.m. No indicator appears for times from midnight to
11:59 a.m. With 24-hour format, time is displayed from 0:00 to 23:59, without any
P (PM) indicator.

Memory
The watch has enough memory to hold up to 121 records for session start
information (date and time), and lap time records. You can record up to 120 lap
times.
Example 1: Single session (from start to reset)
Example 2: Multiple sessions
1. In the Timekeeping Mode, hold down A until the
DST indicator
seconds digits start to flash (about two seconds).
This enables setting of the seconds.
2. Press C to display the DST setting mode.
3. Press D to toggle between Daylight Saving Time (ON)
and Standard Time (OFF).
4. After the setting is the way you want, press A to
return to the Timekeeping Mode.
The DST indicator appears to indicate that Daylight
Saving Time is turned on.
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.

This will result in one of the following, depending on the status of the stopwatch the
last time you exited the Stopwatch Mode.
Stopwatch reset: Timing starts.
One-press timing start from the Timekeeping Mode (direct timing start from the
Timekeeping Mode).
If an ongoing timing operation is paused: Timing remains paused.
If an ongoing timing operation is in progress*: Timing continues to be performed.
* An ongoing stopwatch timing operation continues even if you navigate to
another mode from the Stopwatch Mode.
LAP time
Each press of B records the current lap time. Memory can hold up to 120 lap
time records.
Recording a lap time while there are 120 records in memory will automatically
delete the oldest record to make room for the new one.
The final lap time (time displayed when the elapsed time operation is stopped) is
recorded in memory when the stopwatch is reset to all zeros.
Session start information (date and time) requires one record for each session. A
session is from the start of measurement up the point the stopwatch is reset.
Each lap time uses one record.
Start information (date and time) record + 120 lap time records =
121 records in total
Session 1: Start information (date and time) record + 60 lap time
records = 61 records
Session 2: Start information (date and time) record + 59 lap time
records = 60 records
Total: 121 records
