Casio 3258 Manuale Utente

Operation Guide 3258

•

 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 
infl uence of the conditions listed above becomes even greater.

•

 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.
Mainfl ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles) 
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers) 
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles) 
Shangqiu (China) transmitter: 500 kilometers (310 miles)

•

 As of May 2011, China does not use Daylight Saving Time (DST). If China does go to the Daylight 

Saving Time system in the future, some functions of this watch may no longer operate correctly.

To get ready for a receive operation
1. Confi rm that the watch is in the Timekeeping Mode. If it isn’t, use 

D to enter the Timekeeping Mode 

(page E-24).

2. The antenna of this watch is located on its 12 o’clock side. Position the watch with 12 o’clock facing 

towards a window as shown in the nearby illustration. Make sure there are no metal objects nearby.

•

 Signal reception normally is better at night.

•

 The receive operation takes from two to seven minutes, 

but in some cases it can take as long as 14 minutes. Take 
care that you do not perform any button operation or 
move the watch during this time.

3. What you should do next depends on whether you are using Auto Receive or Manual Receive.

•

 Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto 

Receive” below for details.

•

 Manual Receive: Perform the operation under “To perform manual receive” on page E-18.

•

 With Auto Receive, the watch performs the receive operation each day automatically up to six times (up 

to fi ve 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.

•

 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 confi guring settings.

•

 You can use the procedure under “To turn auto receive on and off” (page E-21) to enable or disable 

auto receive.

1. Use 

D to select the Receive Mode (R/C) as shown on page E-24.

2. Hold down 

A until RC Hold appears on the display and then 

disappears.

•

 A signal level indicator (L1, L2, or L3, see page E-20) will appear 

on the display after reception starts. Do not allow the watch to 
move and do not perform any button operation until GET or ERR
appears on the display.

•

 If the receive operation is successful, the reception date and time 

appear on the display, along with the GET indicator.
The watch will return to the Timekeeping Mode if you press 

D or 

if you do not perform any button operation for about two or three 
minutes.

•

 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 two or three minutes.

Note
You can interrupt a time calibration signal reception operation by 
pressing any button.

If there was a previously 

successful reception

If there was a previously 

successful reception

During manual receive, the signal level indicator displays the signal level 
as shown below.

As you watch the indicator, keep the watch in a location that best 
maintains stable reception.

•

 Even under optimum reception conditions, it can take about 10 

seconds for reception to stabilize.

•

 Note that weather, the time of day, surroundings, and other factors all 

can affect reception.

Enter the Receive Mode (page E-24).

•

 When receive is successful, the display shows the time and date that 

receive was successful. - : - - indicates that none of the reception 
operations were successful.

•

 To return to the Timekeeping Mode, press 

D.

Note
The receiving indicator will not be displayed if you have adjusted the 
time or date setting manually since the last receive operation.

1. Enter the Receive Mode (page E-24).

2. Hold down 

E until On or OFF fl ashes on the display. This is the 

setting screen.

•

 Note that the setting screen will not appear if the currently selected 

Home City is one that does not support time calibration reception.

3. Press 

A to toggle auto receive on (On) and off (OFF).

4. Press 

E to exit the setting screen.

•

 Strong electrostatic charge can result in the wrong time setting.

•

 Even if a receive operation is successful, certain conditions can cause the time setting to be off by up 

to one second.

•

 The watch is designed to update the date and day of the week automatically for the period January 1, 

2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed 
starting from January 1, 2100.

•

 If you are in an area where signal reception is not possible, the watch keeps time with the precision 

noted in “Specifi cations”.

•

 The receive operation is disabled under any of the following conditions.

– While power is at Level 3 (L) or lower (page E-10)
– While the watch is in the power recovery mode (page E-11)
– While a sensor operation is being performed
– When the watch is in the function sleep state (“Power Saving”, page E-13)
– While a countdown timer operation is in progress (page E-91)

•

 A receive operation is cancelled if an alarm sounds while it is being performed.

•

 The Home City setting reverts to the initial default of TYO (Tokyo) whenever the battery power level 

drops to Level 5 or when you have the rechargeable battery replaced. If this happens, change the 
Home City to the setting you want (page E-28) .
