I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.
Being a user of older radios of many kinds, preferring them over more modern rigs, this manual was invaluable in the programming of my two. I now know for certain what the assorted buttons functions are, and am very grateful to have found this excellent site. Many thanks for your assistance, Tony.

If the display of the watch is blank...
If the SLEEP indicator is on the display, it means that the display is blank because the watchâs Power Saving function has turned off the display to conserve power. Power Saving automatically turns off the display and enters a sleep state whenever your watch is left for a certain period where it is dark. â¢ The initial factory default setting is Power Saving on. â¢ The watch recovers from the sleep state if you move it to a well-lit area*, if you press any button, or if you angle the watch towards your face for reading. * It can take up to five seconds for the display to turn on. â¢ See âPower Saving Functionâ for more information.

Timer Mode The countdown timer gives you a choice of two modes: auto-repeat and elapsed time. Auto-repeat The auto-repeat mode automatically restarts the countdown from the countdown start time you set whenever zero is reached. â¢ The auto-repeat mode is best when timing the starts of match races. â¢ Even if you start a countdown operation from the reset time, the countdown automatically restarts from the countdown start time whenever it reaches zero. â¢ Auto repeat timing repeats up to seven times.
Elapsed Time When the end of the countdown is reached in the elapsed time mode, the timer automatically switches to an elapsed time measurement operation. â¢ The elapsed time mode is best when timing the speed of yachts during ocean races. â¢ The elapsed time operation is performed in one-second increments up to 99 hours, 59 minutes, 59 seconds.

Countdown Timer Beeper Operations
The watch beeps at various times during a countdown so you can keep informed about the countdown status without looking at the display. The following describes the types of beeper operations the watch performs during a countdown. Countdown End Beeper The watch beeps each second of the final 10 seconds before a countdown reaches zero, and at zero. The first five beeps (seconds 10 through 6) are higher pitched than the final five beeps (seconds 5 through 1). The watch emits a longer beep to signal when the countdown reaches zero. â¢ The countdown end beeper always sounds, regardless of the on/off status of the progress beeper. Progress Beeper The progress beeper actually includes two beepers: a reset time beeper and a reset period progress beeper. â¢ The reset time beeper and reset period progress beeper sound only while the progress beeper is turned on.
4. Press A to exit the setting screen. â¢ See âPower Saving Functionâ for details about configuring Power Saving settings. â¢ The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is applied in all modes. â¢ The day of the week is automatically displayed in accordance with the date (year, month, and day) settings.
The countdown timer can be set within a range of one minute to 60 minutes. An alarm sounds when the countdown reaches zero. The countdown timer has two modes: auto-repeat and elapsed time, and a progress beeper signals the progress of the countdown. All of this makes the countdown timer a valuable tool for timing the start of a yacht race. â¢ All of the operations in this section are performed in the
Reset Time Beeper The reset time beeper is similar to the countdown end beeper. When the progress beeper is turned on, the watch beeps each second of the final 10 seconds before the countdown reaches the reset time. Reset Period Progress Beeper The reset period is the portion of the countdown between the reset time and zero. When the progress beeper is turned on, the watch emits four short beeps at the top of each minute during the reset period, and 30 seconds before the end of the countdown.
