How to set time on ProTrek SPF-100

1. In the Timekeeping Mode, hold down A until the seconds digits start to flash, which indicates the setting screen.

• While the seconds digits are flashing, press D to set the seconds count to 00.

2. Press C to move the flashing in the sequence shown below to select other settings.

• See “Daylight Saving Time (DST)” for details on the DST setting and “Adjusting Display Contrast” for information about contrast.

3. Use C to move the flashing to the hour, minutes, year, month, and day, and make the settings you want for each.

• While the hour, minutes, year, month, or day setting is flashing, use D (+) and B (–) to change it.
• When the 12/24-hour setting is selected, press D to toggle between 12-hour (1CL) and 24-hour (CZL) timekeeping.

4. Press A twice to exit the setting screen.

• The day of the week is automatically displayed in accordance with the date (year, month, and day) settings.
• The year can be set in the range of 2000 to 2039.
• The watch’s built-in full automatic calendar automatically 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.
