Timer Mode

In timer mode the SC-1 provides a countdown timer that is user configurable to specific start sequences.

The start sequence is defined by selecting minute marks in device settings. For example, a classic dingy start with a start horn at 5 minutes followed by horns at 4, and 1 minutes is defined by selecting 5, 4, 1 minute marks. The timer will start from and reset to the highest minute mark. Then the timer will synchronize to subsequent minute marks. The classic dingy start sequence will start from and reset to 5:00 and will synchronize to 4:00 and 1:00.

The timer can be configured to roll over to the timer sequence start value and continue counting. If the rollover is enabled, for a classic dingy 5, 4, 1 start, the timer counts down in the following manner. 0:03, 0:02, 0:01, 0:00, 4:59, 4:58... If the rollover is disabled the countdown will reset to 5:00 at 0:00.

The following diagram shows the SC-1 with both the upper and lower displays in timer mode indicating one minute and 36 seconds remaining before the start. Note that there is no mode indicator for timer mode on the upper display. Timer mode on the upper display is indicated only by the presence of a colon.

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.
