2. OPERATION CHART: MODULE QW-3334
Power saving causes the watch to automatically enter a sleep state to save power whenever the watch is left in the dark. The Power Saving feature of the watch is turned on at the factory. •Note that the watch may also enter the sleep state if its face is blocked from light by your sleeve. ■How the sleep state works There are actually two sleep state levels, a “display sleep state” and a “function sleep state”.
•Display sleep state
The display sleep state is triggered whenever the watch is left in the dark for about one hour between the hours of 10 p.m. and 6 a.m. The display sleep state causes the display to go blank.
•Alarms and the Hourly Time Signal continue to operate
normally while the watch is in the display sleep state. Even when the watch is in the display sleep state, analog time timekeeping and auto signal receive are both performed.
•The watch does not enter the display sleep state if it is in the
Timer Mode or Stopwatch Mode.
•Function sleep state
The function sleep state is triggered whenever the watch is left in the dark for six or seven days.
•Alarms and the Hourly Time Signal are also disabled while the
watch is in the function sleep state. Analog time timekeeping and auto signal receive are not performed while the watch is in the function sleep state.
•Timekeeping functions continue to operate normally in the
function sleep state.
■To recover from the sleep mode Place the watch in an area that is well-lit, press any button, or angle the watch towards your face to illuminate the display using the auto light. •It can take up to two seconds before the display re-appears after
you place the watch in a well-lit area.
■To turn power saving on and off See the procedure under “Manually Setting the Time and Date”.
Leaving the watch in a drawer or anywhere else it is dark can cause the power saving mode to trigger in order to conserve battery power.

■Positioning Your Arm Correctly •You should be wearing the watch on the outside of your wrist
when using the auto light switch.
•Make sure that the left (9 o’clock)
and right (3 o’clock) sides of the watch are within
±
15 degrees of
being parallel with the ground. The auto light switch may not operate properly if the angle is greater.
Important! •The light may be difficult to see if you turn it on under bright
sunlight.
•If you press the Lbutton or if an alarm operation starts while the
display is illuminated, illumination will turn off.
■Charging Precautions Avoid charging the watch in the following locations, and anywhere else the watch may become very hot. •On the dashboard of an automobile parked in the sun •Very close to an incandescent light source or other sources of
heat
•In a location exposed to direct sunlight for long periods Note that the display panel may become black under very high temperatures. This is temporary, and the display will appear normal again at lower temperatures.
Depending on the light source you are using, the case of the watch may become quite hot during charging. Take care to guard against burn injury after charging.
■Charging the Battery Point the solar panel (face) of the watch at a light source. •Remember that even a partial blockage of the solar cell reduces
charging efficiency.
Example: Positioning the watch

•Note that the above charging times are for reference only. Actual
charging time depends on a variety of environmental factors.
The power supply of this watch uses a solar cell to generate electrical power, which is stored by a rechargeable battery. Using or storing the watch where it is not regularly exposed to light, or allowing it to be blocked from light by your sleeve as you are wearing it can cause the power of the rechargeable battery to run down. To ensure stable operation, be sure to allow the watch to be exposed to light as much as possible when you are wearing or storing it.
Note that all data in memory and all settings are cleared whenever you allow the level of the rechargeable battery to drop to Level 4.
■Flashing RECOVER Indicator If you use the light or alarms a number of times during a short period, a RECOVER indicator flashes in the top dial, and the following operations become disabled as battery power recovers. •Illumination •Alarm and Hourly Time Signal •Time calibration signal reception Normal operation will return after the battery recovers.
Power Supply
Auto Light Precautions •Frequent use of the auto light can run down the battery. •The auto light switch may cause the display to illuminate when
your sleeve covers the display of the watch.
•The display may not illuminate immediately when you angle the
watch towards your face. This does not indicate malfunction.
•The display remains lit for the currently set illumination duration
(1.5 or 2.5 seconds) only, even if you leave the watch angled towards your face.
•The auto light switch is automatically disabled whenever battery
power is at Level 3 or lower.
•The display may illuminate unintentionally when you wear the
watch on the inside of your wrist, when you shake your arm, or when you raise your arm. Be sure to turn off the auto light switch whenever you do not need illumination.
•Keep the auto light switch turned off whenever you are wearing
the watch on the inside of your wrist.
•Electro-static charge and magnetism can interfere with auto light
operation and even make operation impossible. If this happens lower your arm to the starting position and then raise it again. If you still have trouble with illumination, try lowering your arm down to your side and then raise it to your face for reading.

•Exposing the watch to direct sunlight or other strong light may cause
the battery level indicator to momentarily indicate a level that is higher than the actual battery level. Because of this, you should wait for a short while after charging to check the battery level indicator.
•Even if the battery level drops all the way to Level 4, you will still
be able to recharge the battery and use the watch again.
•When recharging from Level 4, set the current time and date after
the battery level recharges to Level 3. At this time you should continue to expose the watch to light so it can charge up to Level 2 or Level 1.
■Start charging at Level 3! Battery Level 3 indicates that remaining battery power is very low. Be sure to expose the watch to light for recharging as soon as possible after the battery level indicator shows Level 3. Illuminating the Display with the Auto Light Switch
The auto light switch automatically illuminates the display whenever you angle the watch towards your face for reading, but only when it is dark. You can use the procedure under “Specifying the Illumination
Duration”to configure the illumination duration as
approximately 1.5 seconds or 2.5 seconds. •The auto light switch does not illuminate the display when
surrounding light is bright.
The auto light switch illuminates the display in all modes.
Turning the Auto Light Switch On and Off In any mode, hold down the Lbutton for about two seconds to toggle the auto light switch on (auto light switch on indicator displayed in the upper dial) and off (no indicator displayed).

What is a radio-controlled watch? Your radio-controlled watch is designed to receive a time calibration signal that contains standard time data and adjust its current time setting accordingly.
Signal is received using built-in antenna.
Signal Data

Atomic Clock
Transmitter Long-wave
Calibration Signal
Internally
Decode
Watch
Time Data
Watch decodes received data and converts it to time data. Time is adjusted according to time data.
After the watch receives the time calibration signal, it performs internal calculations to determine the current time. Because of this, there may be an error of up to one second in the displayed time.
Calibration Signal •The Japanese calibration signal (Call Sign: JJY) is maintained by
the independent Japan Ministry of Posts and Telecommunications Communication Research Laboratory (CRL). It is a long wave signal transmitted 24 hours a day from the Mt. Otakadoya transmitter (40kHz) located in Tamura-gun, Fukushima Prefecture, and from the Mt. Hagane transmitter (60kHz) located on the border between Saga Prefecture and Fukuoka Prefecture.
•The U.S. calibration signal (Call Sign: WWVB) is transmitted by
the National Institute of Standards and technology from Fort Collins, Colorado.
Though the calibration signal is normally transmitted 24 hours a day, transmission may be interrupted occasionally due to maintenance, lightening, etc.

•The contents of the above table are current as of December 2003. •Time differentials in the above table are in accordance with
Universal Time Coordinated (UTC).
Troubleshooting Cannot perform manual reception. Cause: •Manual receive can be performed in the
Timekeeping Mode only.
•Manual receive cannot be performed
while a timer operation is in progress.
•The Home City is set to a city other than
TYO (Tokyo), NYC (New York), CHI
(Chicago), DEN (Denver), or LAX (Los
Angeles).
Corrective Measures: •Perform manual receive in the
Timekeeping Mode.
•Change the Home City to TYO (Tokyo),
NYC (New York), CHI (Chicago), DEN (Denver), or LAX (Los Angeles). Correctly set the Home City as detailed under “Manually Setting the Time and
Date”.
The receive ( ) icon is not on the display even though auto signal reception is turned on. Cause: •The receive ( ) icon appears after the
watch successfully receives the calibration signal and adjusts the current time setting.
•A single receive operation was not
successful.
•The watch is not in the Timekeeping
Mode or World Time Mode when an auto reception time is reached.
•
You performed manual reception, which clears the receive ( ) icon from the display.
Corrective Measures: •Check to make sure the watch is in a
location where it can receive the signal.
•Place the watch in a location where
reception conditions are good.
•Make sure that the watch is in the
Timekeeping Mode or World Time Mode during the auto reception times.
Calibration Signal Reception Precautions •Auto reception can be performed while the watch is in the
Timekeeping Mode or World Time Mode only.
•Signal reception cannot be performed while a timer operation is in
progress.
•Receipt of a calibration signal causes the digital time to be
adjusted first, followed by adjustment of the analog time. In order to ensure correct adjustment of the analog time, be sure to match the analog time with the digital time before performing a signal receive operation.
•Operating any button while auto reception is in progress will
cause the watch to beep and then exit the receive operation.
•Make sure you are within the range of the calibration signal
transmitter before performing the reception operation. Remember that geographic contours, nearby buildings, the season, the time of day can make reception impossible even when you are within range of the transmitter.
•Proper reception may be impossible if there is something blocking
the signal. If reception is unsuccessful, try again.
•This watch is designed to adjust its current time setting in
accordance with the calibration signal transmitted in Japan and the United States only. Note that you will need to make your own adjustments when using this watch outside of Japan or the United States, or in any area that is outside the range of one of the receivable time calibration signal transmitters.
•When the watch is unable to adjust its time signal using the
calibration signal for some reason, timekeeping accuracy is within
±
15 seconds per month.
•Strong electrostatic charge can cause timekeeping error. •Signal reception is cancelled if an alarm starts to sound while it is
being performed.
•The watch’s calendar shows dates up to the year 2099.
Attempting a receive operation after that causes an error.
DST Indicator
•If you cannot receive the calibration signal or if the current time
setting is incorrect after signal reception, check the current setup of the watch. •The following are the watch’s factory default settings, which are
configured automatically whenever you have the battery of the watch replaced.
Transmitter Mode
Home City Summer Time
Tokyo Auto Japan transmitter select (40kHz/ 60kHz) Auto switching (according to signal data)
Time setting is incorrect following signal reception. Cause: •If the current time is advanced by one
hour, it probably means that summer time is turned on (indicated by the DST indicator).
•If there is a large error in the setting, it
probably means that the wrong Home City is selected.
Corrective Measures: •Correctly configure the summer time and
Home City settings as detailed under “Turning Summer Time On and Off”and
“Manually Setting the Time and Date”.
Cannot configure signal reception settings. Cause: •The Home City is set to a city other than
TYO (Tokyo), NYC (New York), CHI
