BACKLIGHT

Auto light switch on indicator

A-LIGHT

• The illumination provided by the backlight may be hard to see when viewed under direct sunlight.

• The watch will emit an audible sound whenever the display is illuminated. This is caused by a transformer that vibrates when the EL panel lights up. It does not indicate malfunction of the watch.

• The backlight automatically turns off whenever an alarm sounds.

To manually turn on the backlight

In any mode, press L to illuminate the display for about two seconds.

• The above operation turns on the backlight regardless of the current auto light switch setting.

About the Auto Light Switch

Turning on the auto light switch causes the backlight to turn on whenever you position your wrist as described below.

• Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when it is not needed, which shortens battery life.

The backlight uses an EL (electro-luminescent) panel that causes the entire display to glow for easy reading in the dark. The watch’s auto light

switch automatically turns on the backlight when you angle the watch towards your face.

• The auto light switch must be turned on (indicated by the auto light switch on indicator) for it to operate.

Note

• The electro-luminescent panel loses illuminating power after very long use.

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

Parallel to ground

• The backlight turns off in about two seconds, even if you keep the watch pointed towards your face.

• The backlight may not light if the face of the watch is more than 15 degrees off the parallel as shown below. Make sure that the back of your hand is parallel to the ground.

Parallel to ground

• Static electricity or magnetic force can interfere with proper operation of the auto light switch. If the backlight does not light, try moving the watch back to the starting position (parallel with the ground) and then tilt it back toward you 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.

• Under certain conditions the backlight may not light until about one second or less after turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight.

CHANGING THE MEASUREMENT UNITS

You can change the measured values displayed by the watch between the following units. Altitude: meters (m) Temperatures: Celsius (°C) Barometric Pressure: hecto-pascals/millibars (hPa/mb)

Some countries call this unit hecto-pascal (hPa), while other countries call it

millibars (mb). It really makes no difference, because 1 hPa = 1 mb. In this manual, we will refer to hPa/mb or hPa (mb).

Important!

• Certain measurement functions are automatically terminated when you change the measurement units. Be sure that you perform this operation before starting actual measurements.

• Changing the altitude unit of measurement automatically switches the altitude alarm off.

• Changing the barometric pressure unit of measurement automatically restarts the barometric pressure graph from a new value.

• Changing any of the units of measurement immediately starts to display newly measured data in the unit you specify. It also affects the unit of measurement for any data already stored in memory.

BAROMETER FUNCTIONS

This watch uses a pressure sensor to measure air pressure. This sensor can be calibrated.

Important!

The barometer that is built into this watch measures changes in air pressure, which you can then apply to your own weather predictions. It is not intended for use as a precision instrument in official weather prediction or reporting applications.

Example barometer applications

• Before going mountain climbing, you can take readings to find out the probable upcoming weather.

• You can predict the weather for golf or other outdoor activities.

About barometric measurements

The barometer automatically takes measurements every two hours (starting from midnight), regardless of what mode you are in. Barometric pressure measurements are also taken every five seconds for three minutes after you display the Timekeeping Mode’s Barometric pressure/Temperature screen. The last measurement result, along with the current temperature is displayed in the Barometric pressure/Temperature screen.

Understanding the barometer screen

1. Use C to enter the Timekeeping Mode.

2. Press D to display the Barometric Pressure/Temperature screen.

• If you do not press any button for 10 or 11 hours, the watch automatically returns to the Timekeeping screen.

(Barometric Pressure/Temperature)

1 The barometric pressure graph shows the barometric readings for the

past 26 hours. The flashing point on the right of the display is the point for the last measurement.

2 The display shows “– – – – hPa/mb” (or inHg) if a measured value falls

outside the range of 460 hPa/mb to 1100 hPa/mb (13.55 inHg to 32.45 inHg). The normal display will return as soon as the pressure returns within the allowable range.

Using the barometric pressure graph

Changes in barometric pressure are caused by changes in the weather and temperature. The following shows how to interpret the data that appears on the barometric pressure graph.

A built-in altimeter uses a pressure sensor to detect the current air pressure, which is then used to estimate the current altitude in accordance with ISA (International Standard Atmosphere) values for altitude and air pressure. If you preset a reference altitude, the watch will also calculate the current relative altitude based on your preset value. Altimeter functions also include data storage memory and an altitude alarm.

Important!

• This watch estimates altitude based on air pressure. This means that altitude readings for the same location may vary if air pressure changes.

• Sudden changes in the weather make it impossible to produce accurate altitude readings.

• This watch employs a semiconductor pressure sensor, which is affected by temperature changes. When taking altitude measurements, be sure to do so while ensuring that the watch is not exposed to temperature changes.

• Do not use this watch while participating in sports where there are sudden altitude changes. Also, do not use this watch for applications that demand professional or industrial level precision. This watch should not be used while engaging in the following activities: sky diving, hang gliding, paragliding, gyrocopter riding, glider riding, etc.

Applications

When no reference altitude is preset:

• The watch produces approximate altitude readings.

When a reference altitude is preset:

• Before beginning the climb, set the reference altitude to 0 m at the foot of the mountain. This makes it possible to determine the difference in altitude between the reference point and your destination.

• To determine the height of a tall building, set the reference altitude to 0 m on the ground floor. Note, however, that if the building is pressurized or air conditioned, you may not be able to get a good reading.

• To determine the difference in altitude between your house and another location, set the reference altitude to 0 m at your house, and then check the reading when you arrive at the other location.

• When mountain climbing, you can input the altitude from a marker as your reference altitude, which will then let you know your altitude as your climb proceeds. The following conditions will prevent you from obtaining accurate readings:

When air pressure changes because of changes in the weather Extreme temperature changes When the watch itself is subjected to strong impact

About altitude measurements

There are two types of altitude measurements: those for displayed data (Altimeter Mode measurement) and those for memory data (memory measurements; See “Memory measurements”).

Altimeter Mode measurement

This type of measurement is performed only when the watch is in the Altimeter Mode. As soon as you enter the Altimeter Mode, measurements are taken every five seconds for the first three minutes. After that, measurements are taken every two minutes. The display unit for Altimeter Mode measurements is 5 m (20 feet), and the display range is 0 to 6000 m (0 to 19680 feet).

• The measured altitude may be a negative value in cases where there is a reference altitude value set or because of certain atmospheric conditions.

Understanding the altimeter display

Use C to enter the Altimeter Mode. Note that once you enter the Altimeter Mode, if you do not press any button for 10 or 11 hours, the watch automatically returns to the Timekeeping Mode.

every five seconds. It does not flash during the measurements taken every two minutes.

2 The mark next to AUTO flashes while a memory measurement is in

progress. The indicator stops flashing while no measurement is being performed.

Memory measurements

Memory measurements are taken independently of Altimeter Mode measurements and stored directly into memory (along with temperature measurements) for later recall. There are two types of memory measurements: “Auto Memory Measurements” and “Manual Memory Measurements”.

Auto Memory Measurements

With auto memory measurement, the watch continuously performs measurements whenever the minutes in the Timekeeping Mode reach 00, 15, 30, or 45, until you switch auto measurements off. The watch continues to take measurements regardless of whether or not you change modes, so you can keep a running log of temperature and altitude changes automatically.

Manual Memory Measurements

You can use the manual procedure to take a reading anytime you want to store your current altitude data into memory for later recall. Manual memory measurements can be performed only while the watch is in the Altimeter Mode.

About the memory...

Each memory item (auto or manual) stored by the watch consists of the current altitude, plus the date, time, and temperature. Data is stored in the same sequence that it is input. Memory can hold a total of 50 sets of data, which is enough to store 12 hours and 15 minutes of auto memory data (if you do not take any manual readings during that time).

Important!

Further auto or manual memory measurements become impossible whenever memory is full. The message that memory is full. Always check the amount of memory remaining before starting memory measurements, and delete data if necessary.

Selecting Auto or Manual Memory Measurement

under “Selecting Auto or Manual Memory Measurement” to select manual memory measurement.

2. Hold down D until the watch emits a short beep, indicating that a measurement is taken.

3. Repeat step 2 whenever you want to take a reading.

Setting a Reference Altitude

After you set a reference altitude, the watch automatically calculates the difference between the current altitude and your preset value. The altitude measurements produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you set the reference altitude during your climb whenever one is available.

About the Target Altitude Graph

Graphic area

˚C

The start point differs according to what type of memory measurement

procedure you are using. With auto memory measurements (AUTO shown on the display), the start point is the first altitude measured. With manual memory measurements (MANUAL start point is 0 m (0 ft).

• The target altitude graph is not shown on the display if the altitude alarm is

off.

Example:

• The display below would appear at a current altitude of 160 m when you are using manual memory measurement with a target altitude setting of 200 m. Eight points on the graph are darkened because you are 8/10 of the way to your target.

• The display below would appear at a current altitude of 160 m when you are using auto memory measurement with a target altitude setting of 200 m and a starting point of 100 m. Six points on the graph are darkened because you are 6/10 of the way to your target.

The Target Altitude Graph appears in the graphic area of the display in the Altimeter

Mode. It divides the difference between your start point the altitude alarm into 10 equal parts. It then shows a graph that shows your current location, to give you some idea of how much farther you must go to reach your altitude

To fasten the two-piece band on your wrist

1. Wrap the wide inner band around your wrist, pressing the fasteners on the bands together to secure it.

• Band fasteners can separate when wet.

Buckle

2. Wrap the narrow outer band around your wrist. Grasping the buckle between your thumb and middle finger, insert the band into the buckle while pressing down the top of the band with your forefinger.

• The buckle locks with a snap when fastened.

• Actual buckle shape depends on watch model.

To adjust the length of the two-piece band

1. Slide the buckle on the band to adjust the band length.

2. Pass the band around the outside of the buckle.

3. Double the band back around the inside of the buckle and then pull on the end to tighten.

Using the Band Clip

Be sure to attach the band clip to the watch and then attach the watch to your belt whenever using the Trekking Counter. Failure to attach the Trekking Counter correctly to your belt can produce poor measurement accuracy.

To attach the band clip

1. Remove the band from the watch.

• If your watch was a one-piece band with a

fixed buckle, pull the band to remove it from the watch.

• If your watch has a two-piece band with

removable buckle, remove the buckle from the outer band and then slide the band from the watch.

Trekking Counter Precautions

• Be sure to turn off the Trekking Counter when: taking part in any activity

involving jumping, bending, stretching, etc.; resting; riding a bicycle, train, bus, or any other vehicle that vibrates.

• Any of the following can cause measurements to lose accuracy: walking on

loose ground, up or down steep slopes; running; shuffling your feet; uneven strides; walking in sandals, shower shoes, or similar footwear; walking up or down stairs.

• Measurements may become inaccurate or even fail entirely if the watch is

exposed to strong magnetic force.

• Always be sure to fasten the band clip to the bottom (6 o’clock position) of

the watch, and not to the top (12 o’clock position).

• Take care to avoid dropping the watch while walking.

• When using the Trekking Counter, make sure the watch is not resting

against your clothing or waist pack. If the watch is not hanging loosely, the Trekking Counter will not be able to count your steps correctly.

• When walking up stairs or performing other activities that requires raising of

the leg, measurement accuracy can be affected by the watch bumping against or riding on your leg. In such a case, try to position the band clip so it hangs naturally, away from your leg.

• Wear the band clip so it is located in front of your body. This helps to make

sure the watch and band clip do not become accidentally caught on something and pulled off your belt.

Leather Band

To fasten the band on your wrist

1. Pass the end of the band through the opening in the lock cover and then through the belt loop.

2. Fold the buckle over the two metal pieces, and press down on the buckle until it snaps into place.

3. Close the lock cover and press down until it snaps into place.

• To remove the band from your wrist, pull up on the

sides of the lock cover with your thumb and forefinger to release it, and then unfold the buckle.

Metal pieces

Buckle

To adjust the length of the band

1. Pull up the flap on the inside of the buckle to release the band, and then slide the band in or out to adjust its length.

Caution! The resistance of the flap is quite strong, so do not use your fingernail when pulling it up. Instead, use a screwdriver or other similar tool.

2. After the band is the length you want, fold the flap back down to lock it in place.

Trimming the tip of the band

Band trimming is optional. Use scissors to cut off the tip of the band to eliminate any excess that protrudes from the buckle after you adjust the length of the band. It is recommended that you cut the band at a point that is 5 to 10 mm inside the tip of the buckle.

Important!

• Always handle scissors and other cutting tools with care to avoid personal

injury.

• Take care not to trim too much off the end of the band. It is probably best to

cut off a little at a time until you get the band to the length you want.

• Cutting the band may cause the ends of the thread of the remaining part to

come loose. If this happens, do not pull on the thread. Trim the loose thread with scissors.
