HOW TO USE THE TACHYMETER

(for models with tachymeter scale on the dial)

To measure the hourly average speed of a vehicle

1 Use the stopwatch to determine how many seconds it takes to go 1 km or 1 mile.
2 Tachymeter scale indicated by Second hand gives the average speed per hour.

Ex. 1

Ex. 1 Tachymeter scale: "80" Second hand: 45 seconds

"80" (tachymeter scale figure) x 1 (km or mile) = 80 km/h or mph

Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or miles and Second hand indicates "80" on tachymeter scale:

"80" (tachymeter scale figure) x 2 (km or mile) = 160 km/h or mph

"80" (tachymeter scale figure) x 0.5 (km or mile) = 40 km/h or mph

To measure the hourly rate of operation

1 Use the stopwatch to measure the time required to complete 1 job.
2 Tachymeter scale indicated by Second hand gives the average number of jobs accomplished per hour.

Ex. 2: If 15 jobs are completed in 12 seconds:

$$ \begin{array}{l} " 3 0 0" (t a c h y m e t e r s c a l e f i g u r e) \times 1 5 j o b s \ = 4 5 0 0 \text { jobs / hour } \ \end{array} $$

Ex. 1

Tachymeter scale: "300" Second hand: 12 seconds tachymeter (gure) x 1 job jobs/hour

NOTES ON OPERATING THE WATCH

*1 • The day of the week is automatically set once the year, month and date are set.
- When the time is set in the 24-hour indication, the world time and alarm time will also be displayed in the 24-hour indication.
*2 The digits except seconds and "12H"/"24H" move quickly if Button D is kept pressed.
- When the seconds read any number from "30" to "59" and Button D is pressed, 1 minute is added.
- When setting the hour digits in the 12-hour indication, check that the AM/PM mark is properly set. In the 24-hour indication, there is no mark.

*3 The hands move counterclockwise by pressing Button A and clockwise by pressing Button D. They move quickly if the respective buttons are kept pressed.

*4 If the watch is left untouched in TIME/CALENDAR SETTING display with the digits flashing, it will automatically return to TIME/CALENDAR mode in 2 to 3 minutes.

*5 The hourly time signal will not ring while the alarm is ringing.

*6 Daylight saving time is a system adopted by some countries to make the best use of daylight during a certain period in summer. Under this system the time is advanced an hour.

- The data on daylight saving time built into the watch's memory was collected as of February 1995, and use of daylight saving time may change when so decided by the countries concerned. In that case, therefore, the watch may not show daylight saving time properly.

*7 The time differences and use of daylight saving time may change in some areas or countries when they are so decided by the countries concerned. In that case, therefore, the watch may not show time differences/daylight saving time properly.

*8 • The digits move quickly if Button D is kept pressed.

- When the time in TIME/CALENDAR mode is set in the 24-hour indication, the alarm time will also be displayed in the 24-hour indication.

- When setting the hour digits in the 12-hour indication, check that the AM/PM mark is correctly set.

*9 If the watch is left untouched in ALARM SETTING display with the digits flashing, it will automatically return to ALARM mode in 2 to 3 minutes.

*10 • The alarm mark is displayed if either of the alarms is engaged.

- Alarm test: Press and hold Buttons C and D at the same time in TIME/CALENDAR mode.

*11 Remarks on stopwatch function:

- After 100 hours have been measured, the stopwatch will automatically be reset to "0:00'00"000".

- Even while the stopwatch is counting, the display can be changed from STOPWATCH to another by pressing Button A.

* The mode indicator for STOPWATCH mode flashes to indicate that the stopwatch is counting. After the stopwatch is used, however, be sure to stop it by pressing Button C as this will help to preserve the battery life.

- When the hourly time signal mark is displayed, a beep sounds with each press of the buttons.

☆☆ When all the segments light up ☆☆

If Buttons C and D are pressed at the same time in TIME/CALENDAR SETTING display, all the segments of the display will light up as shown at right. This is not a malfunction.

Press any one of the four buttons to return to TIME/CALENDAR mode.

BATTERY LIFE INDICATOR

- When the words "BATTERY CHANGE" scroll in the scroll window, replace the battery with a new one as soon as possible. Otherwise, the watch will stop operating in 2 to 3 days. We suggest that you have the battery replaced by a SEIKO DEALER.

* Even after the "BATTERY CHANGE" message appears, time accuracy is not affected.

BATTERY CHANGE

2 Years

The miniature battery which powers your watch should last approximately 2 years. However, because the battery is inserted at the factory to check the function and performance of the watch, its actual life once in your possession may be less than the specified period. When the battery expires, be sure to replace it as soon as possible to prevent any malfunction. For battery replacement, we recommend that you contact an AUTHORIZED SEIKO DEALER and request SEIKO SR1130W battery.

* The battery life may be less than 2 years if:
• the alarm is used more than 20 seconds a day,
- the stopwatch is used for more than 3 minutes a day,
- city selection is made more than 5 times a day,
- the confirmation sound is used more than 10 times a day, and/or
- the time transfer function is used more than once a day.

WARNING

• Do not remove the battery from the watch.
• If it is necessary to take out the battery, keep it out of the reach of children. If a child swallows it, consult a doctor immediately.
  ● Never short-circuit, tamper with or heat the battery, and never expose it to fire. The battery may burst, become very hot or catch fire.

CAUTION

● The battery is not rechargeable. Never attempt to recharge it, as this may cause battery leakage or damage to the battery.

10, 15 or 20 bar watch, be sure to observe the following:

* Do not operate the buttons when the watch is wet with soapy water or shampoo.
* If the watch is left in warm water, a slight time loss or gain may be caused. This condition, however, will be corrected when the watch returns to normal temperature.

* Pressure in bar is a test pressure and should not be considered as corresponding to actual diving depth since swimming movement tends to increase the pressure at a given depth. Care should also be taken on diving into water.

** We recommend that you wear a SEIKO Diver's Watch for scuba diving.

■ TEMPERATURES

+60°C -10°C

Your watch works with stable accuracy within a temperature range of 5^ C and 35^ C ( 41^ F and 95^ F).

Temperatures over 60^ C ( 140^ F) or below -10^ C ( +14^ F) may cause a slight time loss or gain or battery leakage or shorten the battery life.

However, the above conditions will be corrected when the watch returns to normal temperature.
