Functions
- Waterproof watch: time of day, countup (from zero) timer and programmed countdown timer with alarm.
- The countdown can run to zero and count up again, or run to zero and repeat the programmed period.
- Buttons: "MODE", "CLEAR", "PROG", "START/STOP" (marked RONSTAN) and "SYNC". "MODE" toggles between time and timer, whether the timer is running or not.
Setting the Time
- Press "MODE" to put the watch in time mode (no countdown icons above the digits; AM or PM shown in 12 hour mode).
- Hold "CLEAR" approximately 2 seconds until the hour flashes.
- Press "PROG" until the correct hour shows (each press advances 1 hour; hold for fast scrolling). "START/STOP" toggles 12/24 hour while the hours flash.
- Press "MODE" to confirm the hours; set the minutes with "PROG".
- Press "CLEAR" once more: the time is set and running and the display stops flashing.
Countup Option
- In timer mode, with the timer stopped, press "CLEAR": the display shows 0:00.
- Press "START": the timer counts up from zero in minutes and seconds to a maximum of 59 mins 59 secs; an arrow icon shows count-up.
- The count-up can be stopped and restarted as many times as required.
The count-up timer only works when the countdown timer is set to countdown and up, not countdown repeat.
Countdown & Up or Countdown Repeat
- Press "MODE" to leave the clock and reach the timer function.
- Stop the timer ("START/STOP") and set the display to zero ("CLEAR").
- Press and hold "SYNC"; while holding it, press "CLEAR" to toggle between countdown and up and countdown repeat (shown by their icons).
- Release "SYNC" to confirm.
Programmed Countdown
| Programme | Countdown & up | Countdown repeat |
|---|---|---|
| 5,4,1,0 minutes | Single period or multiples | Single period only |
| 5 minute periods | Single period or multiples (e.g. 2 × 5 minutes = 10 minutes) | Single period only |
| 3 minute periods | Single period or multiples | Single period only |
| 1 minute period | Single period or multiples | Single period or multiples |
- Alarm: a short sound every minute; in the last minute at 50, 40, 30 & 20 seconds, then every one of the last 15 seconds.
- Choose the programme: timer stopped and at zero, hold "SYNC" and press "PROG"; each press steps 5,4,1,0 → 5 mins → 3 mins → 1 min → 5,4,1,0. The indicators at the top of the display show which programme is selected.
- Set one period (press "PROG" once) or multiples (press "PROG" several times, countdown and up or the 1 minute programme of countdown repeat), then press "START". The countdown can be stopped and restarted as many times as required.
- At zero, countdown and up switches to counting up (up arrow icon) to 59 mins 59 secs, then starts at 0:00 again – elapsed race time, useful in handicap racing. Countdown repeat reverts to the programmed time and counts down again.
- Once the countdown is running only "START/STOP", "SYNC" and "MODE" work. A single beep confirms any button press that has a function.
- Silence the alarm for visual use only: hold "MODE" for approximately 2 seconds until a short bip; the bell icon disappears. Repeat to switch it back on.
SYNC – synchronising with the starter
- "SYNC" only works during a running countdown. If you started late, or even missed the preparatory signal, just start the watch and press "SYNC" on the next signal: the display drops to the next full minute (5:08 → 5:00; 3:35 or 3:59 → 3:00) and keeps counting down.
- The "SYNC" button is deliberately stiffer than the other click-type buttons so it is not knocked by accident.
Strap and Mounting
- Elastic strap: pass the elastic through the clasp from the bottom to the top, pull to the required tightness, press the clasp firmly closed and push the elastic loop over the spare end.
- The timer case can be turned inside the outer clip for a better viewing angle.
- On the back of the hand: remove the timer and the strap from the outer clip, sew the clip to a glove through its 2 holes, then push the timer back in until it clicks positively.
- On the boom or any flat surface: fit the plastic spacer bar between the boat and the outer clip with countersunk screws or pop rivets. Without the spacer it is virtually impossible to remove the timer from the clip.
Changing the Battery
- Low battery indicator (top left of the display): change the battery; the watch will likely run several days with it on.
- Remove the timer from the outer clip (easier with the strap pulled out of the clip).
- Remove all 6 screws with a cross-point screwdriver and lift off the case back.
- Fit a new CR2032 3.0 Volt Lithium Battery with the +ve contact facing up; do not touch both contacts at once.
- Refit the case back with the battery correctly fitted and the rubber seal seated, and replace the screws without over-tightening (the manual says "4 screws" here, as printed).
- Snap the timer positively back into the outer clip.
