Notes on the radio signal reception Modes supporting this function [LAX] [DEN] [CHI] [NYC] [LON]
■ Receiving the radio signal
There are three ways to receive the radio signal. This watch also incorporates a function to check last radio reception results. → pages 14 and 15

is unsuccessful, the watch tries to receive at 3:00 a.m. and 4:00 a.m.
On demand reception| Receive the signal manually when you want to adjust the time and date.  page 24
Recovery automatic| Reception Receives the signal automatically after charging when the watch stops due to insufficient charge.

• These reception operations take place only when the crown is in the closed position and the watch is not moved.
• When the watch is in a low power state (second hand moving in two second intervals), radio reception will not be attempted.
• Radio signal reception cannot be deactivated.
• Even when this watch receives a radio signal successfully, the accuracy of the displayed time will be dependent on the reception environment and internal processing.
• If the watch is not able to receive the signal, it will operate normally within an accuracy range of ±15 seconds per month.
  ■ During radio reception:
  Remove the watch and place it on a stable surface where it can receive the signal better, such as next to a window.
  • The reception antenna is located at the 6:00 position of the watch. Place the watch with the 6:00 position facing toward the station.
  • While the watch is receiving radio signals (the second hand indicates RX, H, M, or L), do not move the watch as a successful update will not be acheived.

■ Note on the radio signal

This watch receives the radio signal from the two signal stations located in U.S.A. or Germany and automatically adjusts the time and date. The receivable signal stations are listed as follows:

Signal stations

|

Kind of the radio signal

---|---
Fort Collins station, Denver, Colorado State, U.S.A.| WWVB
Mainflingen station, southeast Frankfurt, Germany| DCF77

■ When signal reception is poor
Radio signal reception may be affected by the surrounding environment. High- tension wires nearby or windows containing wire meshes make it difficult to receive radio signal. In this case, you should find another suitable place considering the location of the transmitter station in your region. Then, place the watch at a window facing to the station and attempt manual reception. →pages 24 and 25
If the window contains wire screens, open the window or change the location of the watch.

■ Poor reception areas
It may be difficult to receive the radio signal properly under certain environmental conditions or in areas susceptible to radio noise.

• Near high-tension electrical lines, railway overhead wires or communication facilities
• Inside reinforced concrete buildings, between tall buildings, mountains, or underground
• Near mobile phones that are in use

Time differences that can be set in the alternate time mode
In the alternate time mode, you can set any time difference within the following range relative to the London time.

Daylight savings time
When the daylight savings time is set to ON while the watch operates in the alternate time mode, the indicated time is increased by 1 hour. :

During the Daylight Saving Time season

Some areas observe Daylight Saving Time.

• Daylight Saving Time rules will vary depending on the country or region within a country.

When the watch receives a successful radio signal update for the 5 cities, the Daylight Saving Time setting is automatically updated, provided the user
has not manually turned OFF overridden the Daylight Saving Time setting. If you live in an area that does not receive a radio signal, you will need to update the Daylight Saving Time setting manually. — Page 30

Checking the daylight savings time setting
While the watch is in the time display mode or A-TM
mode and the crown is set at position , perform
the following steps.

1. Press and release the upper right button (B).
   The second hand moves and points to the current setting for daylight savings time (ON or OFF).
   

2. Press and release the upper right button (B).
   The current time display mode is resumed.
   • Even if the button is not pressed, the current time display mode is resumed automatically after about 10 seconds.

5. Return the crown to position to finish the setting.

Precautions for setting the daylight savings time to ON/OFF
When manually changing the Daylight Saving Time from OFF to ON to OFF, this engages the manual override built into the watch. This manual override precludes Daylight Saving Time from being automatically adjusted during the radio signal update.
If this function is not desired, the only way to cancel the manual override is to do the all reset and 0-Positioning outlined. + page 54

• Sharing of daylight savings time setting

• The Daylight Saving Time / standard time is shared by multiple cities and regions within the range of each transmitter station (Germany or  U.S.A.). Whenever radio signal is received from each station, the setting is updated automatically.
• If you manually set the watch to the standard time in a city, the watch will always indicate the standard time for that city without synchronizing with other cities.

If you live in an area that does not observe Daylight Saving Time
Change the daylight savings time setting to OFF  manually. Then, as long as the city is selected, the setting remains OFF and the watch ignores the daylight savings time update direction included in the radio signal.

Solar-powered watch handling precautions

< Always be Sure to Expose Your Watch to Light Regularly>

• Your watch enjoys regular exposure to light. Wearing in situations that prevent light exposure such as long shirt or coat sleeves will prevent your watch from receiving light sufficient for charging. In these instances, supplemental charging may be needed.
• When you take your watch off, try and place it in a bright location. This will ensure your watch receives light for charging and will continue to operate properly. Storing your watch in dark places for extended periods of time may cause the stored energy to become depleted and your watch to stop.

CAUTION Recharging Precautions

• Do not charge your watch at high temperatures (60°C/140°F) as this may cause damage to sensitive components and the watch to
  malfunction.
  Examples:

• Charging the watch too close to a light source which generates a large amount of heat such as an incandescent lamp or
  halogen lamp.

• When charging your watch under an incandescent lamp, be sure to leave 50 cm (19-11/16 inches) distance between the lamp and the watch to avoid excessive heat. Never use a halogen lamp for recharging as these generate excessive heat.

• Charging the watch in a location where the temperature may be the dashboard of a vehicle.
  

< Replacement of Rechargeable Cell>

• Your watch features a cell that does not need regular replacement. However, after an extended period of time, power consumption may increase due to deterioration of lubrication in the movement. This may result in shorter than expected run time. Be sure to have your watch regularly inspected by an Authorized Service Center. Note: Regular maintenance is not covered under the terms of the warranty.

WARNING Handling of Rechargeable Cell

• The rechargeable cell should never be removed from the watch. If for any reason it becomes necessary to remove the rechargeable cell from the watch, keep out of the reach of children to prevent accidental swallowing. If the rechargeable cell is accidentally swallowed, consult a doctor immediately.
• Do not dispose of the rechargeable cell with ordinary garbage. Please follow the instructions of  your municipality regarding collection of batteries to prevent the risk of fire or environmental contamination.

WARNING Use Only the Specified Rechargeable Cell

• Never install a conventional battery in your watch. Only use the specified rechargeable cell. Your watch is designed to operate only with the original type of rechargeable cell. It is not designed to run or be used with a conventional type of battery. Installing such a battery may result in overcharging which may cause the battery to burst. This can cause damage to the watch and injury
  to the wearer.
  If for any reason the rechargeable cell needs replacement, be sure to use only the original type rechargeable cell. We recommend contacting your nearest Authorized Service Center for this service.

Water resistance

WARNING Water Resistance

• Refer to the watch dial and the case back for the indication of the water resistance of your watch. The following chart provides examples of use for reference to ensure that your watch is used properly. (The unit “1bar” is roughly equal to 1 atmosphere.)
• WATER RESIST(ANT) xxbar may also be indicated as W.R.xxbar.

Water resistance

• Non-water resistant watches cannot be used underwater or in environments in contact with water.
• Water-resistance for daily use (to 3 atmospheres) means that the watch may be worn while washing your face or in the rain, but is not to be immersed in water.
• Upgraded water-resistance for daily use (to 5 atmospheres) means that the watch may be worn while swimming, but is not to worn while skin diving.
• Upgraded water-resistance for daily use (to 10/20 atmospheres) means that the watch may be worn while skin diving, but not while scuba or saturated diving using helium gas.
• For a metallic, plastic or rubber watchband, wash any dirt off with water. Remove the small amounts of dirt trapped between the crevices of the metallic band with a soft brush. If your watch is not water resistant, be sure not to get the case of the watch wet.

Precautions and usage limitations

CAUTION To Avoid Injury

• Be particularly careful when wearing your watch while holding a small child, to avoid injury.
• Be particularly careful when engaged in strenuous exercise or work, to avoid injury to yourself and others.
• DO NOT wear your watch while in a sauna, jacuzzi or other location where it may become excessively hot. This may result in burns to the wearer and/or malfunction of your watch.
• Be careful when putting on or taking off your watch since there is a risk of pinching your skin or damaging your fingernails depending on the manner in which the band is fastened.

CAUTION Precautions

• Always wear your watch with the crown pushed in to the normal position. If your crown is a screw down type, be sure it is properly screwed down (locked) to the case.
• Do not operate the crown or any buttons when the watch is wet. This may allow the entrance of moisture and cause damage to sensitive components.
• If water enters the watch or the watch fogs up and does not clear up even after a long time, consult  Authorized Service Center for inspection and/or repair.
• If a watch of upgraded water resistance for daily use is immersed in sea water or subjected to excessive perspiration, thoroughly rinse with fresh water and wipe completely dry with a soft cloth.
• If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown, buttons, etc.) may come off.
