Magnetic Declination Compensation

• To compensate for an object's bearing, either subtract westerly (W) magnetic 
   declination or add easterly (E) magnetic declination with the magnetic bearing.
• Example 1: Westerly magnetic declination 23° and the compass needle points 
   323°.  
• TB = MB - W.  When  MB = 323°; W =23° 
• TB = 323° - 23° 
• TB = 300°
• The true bearing is 300°.
• Example 2: Easterly magnetic declination 22° and the compass needle points 278°. 
• TB = MB + E.  When MB = 278°; E = 22°
• TB = 278° + 22°
• TB = 300°
• The true bearing is 300°.
• The Watch allows you to compensate the compass bearing at a place where the 
   magnetic declination is either Westerly declination or Easterly declination. 
• Check the coming section "Calibrating the Compass" for more details of the setting.

Precautions for Battery

15

Battery Life

The battery in your FILA watch is estimated to last for 2 years.

Battery Replacement

If the watch is out of battery, you are recommended to go to the 
authorized FILA service center for correct battery replacement in 
order to retain a valid warranty and avoid any damage on the 
water resistance function.

WARNING!  

Always keep watch batteries away from children. If swallowed, 
contact a doctor immediately. Batteries contain chemical 
substances. They should be disposed of properly according to 
local regulations.

Precautions for Water Resistance

14

 •  Water damage may occur if the push buttons are pressed 

under water.

 •  Should water or condensation appear in the watch, please 

check the watch immediately as corrosion of electronic 

parts can occur inside the case.

All FILA watches are designed to withstand use as indicated on 

the below chart.

Precautions for Straps

 •  Exposure to water often makes a strap fragile and it may 

soon tear. 

 • Don’t apply perfume or moisturizers around your wrist as 

the chemicals can erode the metal, leather and plastic of 

watch straps.

 • The strap’s condition will depend on the owner’s wearing 

habits as well as the climate of the place where the person 

lives. An original replacement on straps is possible to be 

re-ordered through an authorized service center.

 •  PU straps are usually very hard wearing, please wash them 

with mild soapy water only.

 •  There may be discoloration for light color and transparent 

straps after normal wear for some time.

 •  In case if there is any severe or persistent skin reaction, such 

as severe redness, itching, rash or hives, you should stop 

wearing this watch, and consult your doctor.

12

 •  This watch contains electronic components. Never attempt 

to open the case or remove the back cover.

 

• Avoid exposing the watch to extreme temperature, 

chemicals which will damage the watch.

 •  Keep the watch away from the conditions of strong electric 

field and static electricity.

 •  Avoid rough usage or severe impact. The watch is designed 

to withstand impact under normal use. It is advisable to 
subject it to severe impact or rough usage.

 •  Clean your watch occasionally with a soft moistened cloth 

only. Avoid using chemicals, especially soap as the 
waterproof gasket will corrode.

 •  Store the watch in a dry place when it is not in use.

Care and Maintenance

13

Low Battery Detection

•    When low battery is detected, the battery-low icon ‘           ’  will appear for 2 

seconds when entering the Time Mode. It is recommended to replace the battery 
with a new battery.

•    However, if the appearance of low-battery indicator is caused by using the Watch 

under very cold condition, the indicator will disappear when normal temperature 
returns.

For 3-hand movement, the second hand will move per 2 seconds during low battery.

NOTE:

 It is recommended to complete the battery replacement by a certified service 

agency because this Watch contains delicate electronic sensors and components. 

NOTE:

 

The memory will be cleared when the battery is replaced. Follow the previous 

section "Calibrating the Compass" to calibrate the compass before using the Compass.

Power Saving Mode 

•    This Watch has a Power Saving Function which can turn off the LCD display 

so that the battery can last longer.

•    In the Power Saving Mode, the watch function still works normally. (i.e. The 

timekeeping function is still running in Power Saving Mode.)

How to enter/exit the Power Saving Mode

•    To enter the Power Saving Mode, hold down the [L/R] button in Current Time 

Mode for about 5 seconds. “LCD Off” will be shown before it turns off.

•    Press any key in Power Saving Mode to exit this mode and the LCD display 

will be resumed.

of the city which is close to your current position. 

The angle will be input into the Watch during the 

calibration.

•     To select Magnetic Declination Display, press the 

[M] button in Rotation Calibration Display.

•     When the current magnetic declination appears, 

press the [S/S/C] or [L/R] button to increase/ 

decrease the value. 

•     When the setting is completed, hold the [M] button 

to confirm the setting and exit the adjustment

• In the Compass Mode, normally the upper row of the display shows the compass 
  direction.   
• The lower row of the display shows the bearing direction. 

Remark:

Analog movement will be stopped temporarily during compass measurement.

IDLE Display

• If no key is pressed for 1 minute, the watch will go to the IDLE Mode automatically. 
   To activate the compass again, press any button.

Distortion Display

• If distortion is detected, the bearing direction will flash. 
• Please refer to the coming section "Calibrating the Compass" to restore the 
   compass to normal operation when distortion is detected.

What is Magnetic Declination

• The Magnetic North Pole is slightly different from the True North Pole. 
• Like most magnetic compass, the Watch points to the Magnetic North Pole. On 
   the contrary, everything measured on a map is related to the True North Pole.
• The angular difference between Magnetic North Pole and True North Pole is 
   called magnetic declination. Its magnitude (degrees and minutes) and direction 
   (easterly and westerly) depend on where you are in the world. 
• For advance compass user who intends to perform an accurate navigation, the 
   compass must be adjusted for magnetic declination.  
• The Watch also includes a compensation setting for Magnetic Declination. 
   Check the coming section  "Calibrating the compass - Magnetic Declination 
   Mode" for more details.

Magnetic Declination Information

• Most topographic maps include a small arrow which shows the magnetic north 
   pole and magnetic declination information.
• For the benefit of the user, this manual includes the magnetic declinations for 
   some major cities. Check the coming section 'Magnetic Declination at Major 
   Cities' for more details.
• For those cities which their names are not included in the list, please check the 
   online magnetic declination information at:
1.http://ngdc.noaa.gov/geomag-web/ 
2.http://www.geomag.nrcan.gc.ca/calc/mdcal-eng.php 

When to Calibrate the Compass

• The Watch has to employ a compass calibration in one of the following 
   conditions: 
   1) The Watch is being used for the first time, 
   2) The battery is replaced,
   3) The bearing direction digits are flashing,
   4) The compass is used in a location that is apart from the place in which   
       the compass has been calibrated, 
   5) The user intends to maintain the precision of the digital compass.

How to Calibrate the Compass

• The compass calibration includes two different processes: Rotation 
   Calibration Mode and Magnetic Declination Setting. 
• It is advisable to conduct both calibrations from time to time to achieve a 
   more accurate reading.

IMPORTANT:

 If the compass has not been calibrated, the direction made by the 

compass may be inaccurate.
