GENERAL GUIDE

Countdown Timer/Stopwatch Mode

Countdown Timer

Hold

down

The start time of the countdown timer can be set within a range of 1 minute to 24

hours. The operation of the countdown timer is configured to make it useful for timing

yacht races.

All of the operations in this section are performed in the Countdown Timer Mode.

Use the procedure below to switch between the Countdown Timer and Stopwatch.

To switch between the Countdown Timer and Stopwatch

1. Enter the Countdown Timer/Stopwatch Mode.

2. Hold down D for about two seconds to toggle the Countdown Timer Mode and

Stopwatch Mode.

Countdown Timer Mode

Hours

Note that the above steps work only when the currently displayed screen is

initialized (reset). The Countdown Timer is initialized when its start time is displayed,

while the Stopwatch is initialized when it shows all zeros.

See "STOPWATCH" for information about using the Stopwatch.

Countdown Timer Operation

The countdown timer counts down the displayed time in one-second increments,

starting from a countdown start time set by you. A progress beeper beeps each

minute, and each second for the last 10 seconds of the countdown. The operation of

the beeper is very useful for match race and ocean race timing.

Before using the Countdown Timer, you should set the countdown start time and

select either match race timing or ocean race timing as the timing method.

Match Race Timing

When you set up the countdown timer for match race timing, the countdown

automatically restarts from the countdown start whenever zero is reached. This type

of timing is best for match races, with start at regular intervals (every five minutes, for

example).

Ocean Race Timing

With ocean race timing, the stopwatch starts timing automatically as soon as the

countdown reaches zero. This type of timing is best for ocean racing, which is

conducted based on accumulated time following the start.

To set the countdown time

To select the timing method

To use the countdown timer

Press B while in the Countdown Timer Mode to start the countdown timer.

Press B while a countdown operation is in progress to pause it. Press B again to

resume the countdown.

To completely stop a countdown operation, first pause it (by pressing B), and then

press D. This returns the countdown time to its starting value.

Note

Match race timing continues until you stop it. Note that the progress beeper can

down the battery power after long periods, so you should stop the timing operation

when you are not using the countdown timer.

In the case of ocean race timing, stopwatch operation that starts at the end of the

countdown is the same as that for normal Stopwatch Mode timing. See "To measure

times with the stopwatch" for more information. Note that initializing the stopwatch

(clearing it to all zeros) after an ocean race timing operation also initializes the

countdown timer by returning it to its starting value.
