x The areas covered by MOW, HNL and ANC are quite far from the calibration signal  
transmitters, so certain conditions may cause reception problems.  
Fort Collins  
Mainflingen  
x When HKG or BJS is selected as the Home City, only the time and date are  
adjusted according to the time calibration signal. You need to switch manually  
between standard time and daylight saving time (DST) if required. See “To  
configure Home City settings” (page E-42) for information about how to do this.  
The Anthorn signal is receivable  
within this area.

x Even when the watch is within range of a transmitter, signal reception may be  
impossible due to the effects of geographic contours, structures, weather, the time  
of year, the time of day, radio interference, etc. The signal becomes weaker at  
distances of approximately 500 kilometers, which means that the influence of the  
conditions listed above becomes even greater.  
x Signal reception may not be possible at the distances noted below during certain  
times of the year or day. Radio interference may also cause problems with  
reception.

3. What you should do next depends on whether you are using Auto Receive or  
Manual Receive.  
x Auto Receive: Leave the watch over night in the location you selected in step 2.  
See “Auto Receive” below for details.  
In the Timekeeping Mode, hold down D until the watch  
beeps.  
Receiving  
x A signal level indicator (L1, L2, or L3, see page E-32)  
appears on the display after reception starts. Do not  
move the watch or perform any button operation until  
GET or ERR appears on the display.  
x Manual Receive: Perform the operation under “To perform manual receive” on  
page E-29.  
Auto Receive  
x With Auto Receive, the watch performs the receive operation each day  
automatically up to six times (up to five times for the Chinese calibration signal)  
between the hours of midnight and 5 a.m. (according to the Timekeeping Mode  
time). When any receive operation is successful, none of the other receive  
operations for that day are performed.  
Receiving indicator  
x When a calibration time is reached, the watch will perform the receive operation  
only if it is in the Timekeeping Mode or World Time Mode. The receive operation is  
not performed if a calibration time is reached while you are configuring settings.  
x You can use the procedure under “To turn auto receive on and off” (page E-34) to  
enable or disable auto receive.

minutes.  
x If the current reception fails but a previous reception  
(within the last 24 hours) was successful, the display  
shows the receiving indicator and the ERR indicator.  
If the ERR indicator only is displayed (without the  
receiving indicator), it means that all of the receive  
operations over the past 24 hours have failed. The  
watch will return to the Timekeeping Mode without  
changing the time setting if you press D or if you do  
not perform any button operation for about one or  
two minutes.

Troubleshooting  
World Time Mode  
The time for my World Time City is off in the World Time Mode.  
Time Setting  
This could be due to incorrect switching between standard time and daylight saving  
time. See “To specify standard time or daylight saving time (DST) for a city” (page  
E-52) for more information.  
See “Radio Controlled Atomic Timekeeping” (page E-21) for information about  
adjusting the time setting according to a time calibration signal.  
The current time setting is off by hours.  
Your Home City setting may be wrong (page E-42). Check your Home City setting  
and correct it, if necessary.  
Charging  
The watch does not resume operation after I expose it to light.  
This can happen after the power level drops to Level 5 (page E-15). Continue  
exposing the watch to light until the battery power indicator shows H or M.  
The current time setting is off by one hour.  
If you are using the watch in an area where time calibration signal reception is  
possible, see “To configure Home City settings” (page E-42).  
If you are using in the watch in an area where time calibration signal reception is not  
possible, you may need to change your Home City’s standard time/daylight saving  
time (DST) setting manually. Use the procedure under “To change the current time  
and date settings manually” (page E-47) to change the standard time/daylight  
saving time (DST) setting.  
Time Calibration Signal  
The information in this section applies only when LIS, LON, MAD, PAR, ROM,  
BER, STO, ATH, MOW, HKG, BJS, HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI,  
MIA, YTO, NYC, YHZ, YYT, SEL, or TYO is selected at the Home City. You need to  
adjust the current time manually when any other city is selected as the Home City.

You may have the watch configured for Auto Receive of the time calibration signal  
(page E-28), which will cause the time to be adjusted automatically according to  
your currently selected Home City. If this results in the wrong time setting, check  
your Home City setting and correct it, if necessary (page E-42).
