Operation Guide 3334
Location
Reception is difficult and may even be impossible in the locations described below. Avoid such locations when performing signal reception.
•You should think of your watch operating like a radio or TV when it is receiving the calibration signal.
Among or near buildings | Near |
Receiving the Calibration Signal
There are two methods you can use to receive the time calibration signal.
•Auto receive (Reception is performed automatically at midnight, 1:00, 2:00, 3:00, and 4:00 each morning.)
•Manual receive (You initiate reception using a button operation.)
•If reception is not successful for any of the normal auto receive times shown above, auto receive is performed one more time at 5:00 a.m.
•The watch is set up for auto reception at the factory, so all you need to do is to place it in a location that allows good reception each night.
❚Setting Up to Make Reception Easier
Remove it from your wrist and place the watch somewhere so its top (12 o’clock side, where the antenna is located) is facing approximately in the direction of the signal transmitter. Keep it away from metal objects.
❚Time Required for Reception
Signal reception takes anywhere from about two to six minutes.
•Note that when “AUTO” is specified as the frequency selection mode, signal reception can take up to 12 minutes.
•See “Configuring Signal Reception Settings” for more information.
❚Triggering Reception Manually
In the Timekeeping Mode, hold down the D button for about one second until the watch beeps.
•This indicates that manual receive
has started. Ongoing reception is indicated by the receive ( 
) icon and the receive indicator.

When reception is successful
The watch terminates reception and adjusts the current time. Next it beeps, and then the date and time the adjustment was performed appears in the bottom dial.
•The receive (
) icon and the receive indicator remain in the top dial to indicate that reception was successful.
When reception fails
The watch does not adjust its current time setting, and displays
•Even under optimum reception conditions, it can take about 10 seconds for reception to stabilize.
•Use the receive icon and receive indicator to check reception status and to determine the best location for signal reception.
•Note that weather, the time of day, surroundings, and other factors can all affect reception.
If you are experiencing problems with reception, move away from the types of locations described above to a location with better reception, and try again.
•Orienting the watch so it is sideways to the transmitter makes it more difficult to receive the signal.
•Do not move the watch while it is receiving the calibration signal.
“ERR” instead.
•The display also return to the normal timekeeping screen automatically if you do not perform any operation for about one or two minutes.
❚Viewing the Last Reception Date and Time
In the Timekeeping Mode, press the D button. This displays the date and time of the last successful signal reception in the bottom dial.
•To return the bottom dial to the day of the week, press the D button again.
•The bottom dial also returns to the day of the week automatically if you do not perform any operation for about one or two minutes.

Configuring Signal Reception Settings
Use the procedure below to turn auto calibration signal reception on and off. When Tokyo (TYO) is selected as the Home City, you can select either of two different Japanese transmitters for reception.
•For information about selecting a Home City, see “Manually Setting the Time and Date”.
•The initial factory default settings of the watch are TYO (Tokyo) for the Home City, and AUTO (auto select) for the transmitter selection mode.
•You can use the following procedure to turn auto signal reception on or off, and to specify transmitter selection while any one of the following is selected as your Home City: TYO (Tokyo), NYC (New York), CHI (Chicago), DEN (Denver), or LAX (Los Angeles).
1. In the Timekeeping Mode, press the D button to display the last reception date and time in the bottom dial.
• The display will return to the normal timekeeping screen automatically if you do not perform any operation for about one or two minutes.
2. Hold down the A button for about one second until the current transmitter mode starts to flash in the bottom dial.
• This is the transmitter mode setting screen.
3. Use the D and B buttons to cycle through the available transmitter mode settings.
