Radio-controlled Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly.
The time calibration signal includes both Standard Time and Daylight Saving Time
(summer time) data.
This watch is designed to pick up the time calibration signal transmitted in Germany
(Mainflingen), England (Rugby), the United States (Fort Collins) and the time
calibration signals transmitted in Japan.
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration
signal. You can also perform a manual procedure to set the time and date, when
necessary.
The first thing you should do after purchasing this watch is to specify your Home
Time Zone, which is the time zone where you will normally use the watch. For more
information, see “To specify your Home Time Zone” below.
When using the watch outside the range of the time signal transmitters, you will have
to adjust the current time setting manually as required. See “Timekeeping” for more
information about manual time settings.
The U.S. time calibration signal can be picked up by the watch while in North
America.
*The term “North America” in this manual refers to the area that consists of
Canada, the continental United States, and Mexico.
To specify your Home Time Zone
1.In the Timekeeping Mode, hold down B for about five
seconds until the currently selected Time Zone appears
on the display. This is the setting mode.
The GMT differential value indicates the time
difference in hours between Greenwich Mean Time
and the currently selected time zone.
2.Press A to select the time zone you want to use as
your Home Time Zone.

P (GMT–8): Los Angeles, San Francisco, Las Vegas, Seattle/Tacoma, Vancouver,
Tijuana
3. Press B ten times to exit the setting mode.
The watch will also return to the Timekeeping Mode if you do not perform any
operation for about three minutes.
Normally, your watch should show the correct time as soon as you exit the Home
Time Zone setting screen. If it does not, it should adjust automatically after the next
auto receive operation (in the middle of the night). You can also perform manual
receive or you can set the time manually.
Even if the time calibration signal is received correctly, there are some times when
the analog hands may not indicate the correct time. If this happens, use the
procedures under “Adjusting the Home Positions” to check the home positions of the
hands, and make adjustments as required.
The watch will receive the time calibration signal automatically from the applicable
transmitter (in the middle of the night) and update its settings accordingly. For
information about the relationship between time zones (GMT differential values) and
transmitters, see “Transmitters”.
See the maps under “Reception Ranges” for information about the reception ranges
of the watch.
Yo u can disable time signal reception, if you want. See “To set the time and date
manually” for more information.
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to
five times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. For more information, see “About Auto Receive”.
Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see “To perform manual receive”.
Important!
When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 6 o’clock side facing towards a window.
Make sure there are no metal objects nearby.

Time calibration signal reception takes from two to seven minutes, but in some
cases it can take as long as ten minutes. Take care that you do not perform any
button operations or move the watch during this time.

Please note that these instructions are specific to the Casio 4305 watch and may differ for other models.

Why is the watch not receiving the time calibration signal?

The Casio 4305 watch may not be receiving the time calibration signal due to various factors. Here are some possible reasons: 1. Weather and Atmospheric Conditions: Signal reception can be affected by weather conditions, atmospheric changes, and seasonal variations. Changes in the reflectivity of the ionosphere or movement of the ionosphere to higher altitudes may temporarily disrupt signal reception. 2. Signal Range: The reception range of the time calibration signal can vary, and there may be areas where proper reception is impossible. The watch is designed to keep time within ±20 seconds a month in such cases. 3. Home Time Zone Setting: Ensure that the Home Time Zone (GMT differential) setting is correct. Incorrect settings may affect signal reception and time accuracy. 4. Transmitter Availability: The watch receives the time calibration signal from specific transmitters based on the selected home time zone. Check if the transmitter corresponding to your time zone is available and operational. 5. Interference: Radio interference from sources such as high-tension power lines, household appliances, or mobile phones can disrupt signal reception. If you are experiencing issues with time calibration signal reception or incorrect time settings, check the above factors and make necessary adjustments.

How do I switch between Standard Time and Daylight Saving Time on the watch?

To switch between Standard Time and Daylight Saving Time on the Casio 4305 watch, follow these steps: 1. In the Timekeeping Mode, hold down the B button until the currently selected Time Zone appears on the display. This enters the setting mode. 2. Press the B button, and the DST (Daylight Saving Time) setting screen will appear. 3. Use the A button to cycle through the DST settings. The available options are Auto DST (At), DST off (OF), and DST on (On). 4. When the desired DST setting is selected, press the B button nine times to exit the setting screen. Please note that the Auto DST setting automatically switches between Standard Time and Daylight Saving Time based on the time calibration signals received. If you experience difficulties receiving the time calibration signal in your area, it is recommended to switch between Standard Time and Daylight Saving Time manually. These steps should help you switch between Standard Time and Daylight Saving Time on your Casio 4305 watch.

Why is the watch not returning to the Timekeeping Mode automatically?

If the Casio 4305 watch is not returning to the Timekeeping Mode automatically, there could be a few possible reasons. Here are some steps to troubleshoot the issue: 1. Check for Inactivity: The watch is designed to automatically return to the Timekeeping Mode if no operation is performed for a certain period of time.

This feature automatically returns the watch to the Timekeeping Mode after a period of inactivity. To check the setting, go to the Timekeeping Mode and access the settings menu. Look for the Auto Return option and ensure it is turned on. 3. Check Battery Level: Low battery power can affect the watch's functionality. If the battery level is low, the watch may not be able to return to the Timekeeping Mode automatically. Consider replacing the battery if necessary. 4. Reset the Watch: If the above steps do not resolve the issue, try resetting the watch to its factory settings. This can be done by following the instructions in the manual for a factory reset. By following these steps, you can troubleshoot why the Casio 4305 watch is not returning to the Timekeeping Mode automatically.
