Warning!

Things to check before using the watch

1. Check the Home City and the daylight saving time (DST) setting.

Use the procedure under “To conﬁ gure Home City settings” (page E-12) to conﬁ gure your Home City and daylight saving time settings.

Important!

• Proper World Time Mode data depends on correct Home City, time, and date settings in the

Timekeeping Mode. Make sure you conﬁ gure these settings correctly.

2. Set the current time.

See “Conﬁ guring Current Time and Date Settings” (page E-14).

Temperature

• Temperature is displayed in units of 0.1°C (or 0.2°F).

• The displayed temperature value changes to

measured temperature falls outside the range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The temperature value will reappear as soon as the measured temperature is within the allowable range.

TemperatureTemperature

Display Units

You can select either Celsius (°C) or Fahrenheit (°F) for the displayed temperature value. See “To specify the temperature unit” (page E-22).

Temperature Sensor Calibration

The temperature sensor built into the watch is calibrated at the factory and normally require no further adjustment. If you notice serious errors in the temperature readings produced by the watch, you can calibrate the sensor to correct the errors.

Important!

• Incorrectly calibrating the temperature sensor can result in incorrect readings.

Carefully read the following before doing anything. –

Compare the readings produced by the watch with those of another reliable and accurate thermometer.

– If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the

temperature of the watch time to stabilize.

Thermometer Precautions

Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

1. Take a reading with another measurement device to determine the exact current temperature.

2. With the watch in the Timekeeping Mode, press D to enter the Thermometer Mode.

3. Hold down A for about two seconds until the temperature reading disappears from the lower display. Release A at this time, which will cause the temperature reading to ﬂ ash, which indicates the setting mode.

About the Auto Light Switch

While the Auto Light Switch is enabled, illumination will turn on whenever you position your wrist as described below in any mode.

Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes illumination to turn on.

Warning!

Always make sure you are in a safe place whenever you are reading the display of the watch

•

using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not startle or distract others around you.

When you are wearing the watch, make sure that its auto light switch is turned off before riding

•

on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a trafﬁ c accident and serious personal injury.

Illumination

The face of the watch is illuminated for easy reading in the dark. The watch’s auto light switch turns on illumination automatically when you angle the watch towards your face.

• The auto light switch must be enabled (page E-35) for it to operate.

To turn on illumination manually

PressB in any mode (except when a ﬂ ashing setting screen is displayed) to turn on illumination.

• You can use the procedure below to select either 1.5 seconds or three

seconds as the illumination duration. When you press B, the illumination will remain on for about 1.5 seconds or three seconds, depending on the current illumination duration setting.

• The above operation turn on illumination regardless of whether the auto

light switch is enabled or disabled.

• Illumination is disabled while conﬁ guring sensor measurement mode

settings.

To change the illumination duration

1. In the Timekeeping Mode, hold down A until

• When you rel ease A (aft er ADJ appears), SET will be ﬂ ashing in t he lower disp lay. This is the

setting m ode.

2. Use C to cycle through the settings on the lower display until the current illumination duration (

• See the sequ ence in step 2 of t he procedu re under “To chang e the current ti me and date

settings” ( page E-14) for information a bout how to scro ll through set ting scree ns.

Note

• The auto light switch is always disabled, regardless of its enabled/disabled setting, when any one of

the following conditions exists.

Illumination Precautions

• Illumination may be hard to see when viewed under direct sunlight.

• Illumination will not turn on while an alarm is sounding, while high-speed hand movement is in progress,

while a sensor is taking a reading. Illumination will turn on if B is pressed between sensor reading operations.

• Illumination turns off automatically whenever an alarm sounds.

• Frequent use of illumination runs down the battery.

In the Timekeeping Mode, hold down B for about three seconds to toggle the auto light switch between enabled (LT shown in the upper display) and disabled (LT not displayed).

• The auto light switch enabled indicator (LT) is on the upper display in

all modes while the auto light switch is turned enabled.

Auto light switch precautions

E-36

• Illumination may not turn on if the face of the watch is more than 15 degrees above

or below parallel. Make sure that the back of your hand is parallel to the ground.

• Illumination turns off after the preset illumination duration (page E-33), even if you

keep the watch pointed towards your face.

• Static electricity or magnetic force can interfere with proper operation of the auto

light switch. If illumination does not turn on, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards your face again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again.

• You may notice a very faint clicking sound coming from the watch when it is shaken

back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.

Troubleshooting

Time Setting

Why is the current time setting off by a couple of hours?

■

Your Home City setting may be wrong (page E-12). Check your Home City setting and correct it, if necessary.

Why is the current time setting off by one hour?

■

You may need to change your Home City’s standard time/daylight saving time (DST) setting. Use the procedure under “To change the current time and date settings” (page E-14) to change the standard time/ daylight saving time (DST) setting.

Sensor modes

Why can’t I change the temperature unit setting?

■

The temperature unit setting is always Celsius (°C) whenever this case, the setting cannot be changed.

Why does “ERR” appear while a sensor operation is in progress?

■

Why is the low battery alert ﬂ ashing?

World Time:

Alarms: Illumination:

Other: Battery:

48 cities (31 time zones)

Other: daylight saving time/standard time

5 daily alarms (one snooze alarm); Hourly Time Signal

LED (light-emitting diode); Selectable illumination duration (approximately 1.5 seconds or

3 seconds); Auto Light Switch

Button operation tone on/off

Two silver oxide batteries (Type: SR927W)

Approximate battery operating time: 2 years under the following conditions:

• 1 illumination operation (1.5 seconds) per day

• Alarm: 10 seconds/day

• Temperature readings: Once/week

Frequent use of illumination runs down the battery. Particular care is required when using the auto light switch (page E-36).

Battery power is low. Watch operations are disabled while the low battery alert is ﬂ ashing on the upper display. If the low battery alert disappears after battery power recovers but then starts to ﬂ ash again after a short while, it means that you need to have the watch’s battery replaced.

* As of December 2013, the ofﬁ cial UTC offset

for Moscow, Russia (MOW) was changed from +3 to +4, but this watch still uses an offset of +3 (the old offset) for MOW. Because of this, you should leave the summer time setting turned on (which advances the time by one hour) for the MOW time.
