Operating Modes 24
Button Locking
In timer mode when the timer is started or synchronized the buttons lock, if the timeout lock is enabled.
This is to prevent unintentional button pressing after the timer has started or been synchronized. You
must follow the unlock procedure to unlock the buttons to use the button after these events.
Configuring Countdown
The start sequence can be configured by selecting sync points in device settings. For example, a classic
dinghy start with a start horn at 5 minutes followed by horns at 4, and 1 minutes is defined by selecting
5, 4, 1 sync points. The timer will start from and reset to the highest sync point. Then the timer will
synchronize to subsequent sync points. The classic dinghy start sequence will start from and reset to
5:00 and will synchronize to 4:00 and 1:00.
Beeping
The device beeps multiple times before each minute mark during the countdown. The number of
beeps before each minute mark corresponds to the minute remaining. For example, when there are
three minutes remaining, the SC-1 will beep three times and when there are two minutes remaining the
SC-1 will beep twice.
The unit will beep one long followed by 3 short beeps at 1 minute 30 seconds remaining. 3 short beeps
at 30 seconds and 2 short beeps at 20 seconds.
Beginning when there are 10 seconds remaining in the countdown, the SC-1 will beep once every
second. Beginning when there are five seconds remaining in the countdown, the SC-1 will beep twice
every second. When the timer expires the device will beep continuously for three seconds.
