Troubleshooting - Casio 5011 (W3) Operation Manual

When reception is successful
After a receive operation is complete, the watch returns to the
Timekeeping Mode, which shows the newly adjusted time.
When reception fails
The watch will return to the Timekeeping Mode without adjusting the
time setting.
Manual Receive
You will need to perform the operations described below in order to
use Manual Receive.
• Configure the Home City setting of the Timekeeping Mode so it
matches your current location. The Home City must be in a time
zone where calibration signal reception is supported. See:
"Reception Ranges" and "Configuring Home City Settings".
• Put the watch into the Timekeeping Mode. See: "Modes and
Indicators".
• Position the watch correctly (see "Positioning the Watch for Best
Reception").
I To start a Manual Receive operation
In the Timekeeping Mode, hold
down the A A A A button for about A
two seconds until the
indicator hand moves to the
last signal reception result
("Y" or "N"), and then to
"READY" ("R" for some
30
models).
• The hour hand, 24-hour hand,
READY (or R)
and minute hand continue to
operate normally.
• The second hand will stop at "0".

Troubleshooting

1. The watch cannot receive the time calibration signal.
• Is there something in the immediate area that may be interfering
with reception?
Even if you are within the reception range of a transmitter,
electrical noise or objects between you and the transmitter can
interfere with reception. Avoid such areas (see "Positioning the
Watch for Best Reception") during signal reception.
• Are you within the reception range of a transmitter?
See "Reception Ranges" for information about areas where the
watch can receive the signal.
• Are your Home Time settings configured correctly?
See "Configuring Home City Settings".
• Is the signal being transmitted?
Transmission of time calibration signals may be interrupted
occasionally due to maintenance, lightning, etc.
Operation Guide 5011 (W3)
While reception is in progress...
• The indicator hand moves to
"WORK" (or "W" for some
models).
• The hour hand, 24-hour hand,
and minute hand will continue to
operate normally.
• Do not perform any watch
operations while signal reception
30
is in progress (indicator hand at
"WORK" or "W").
• Under some reception conditions,
WORK (or W)
the indicator hand may cycle
between "READY" (or "R") and
"WORK" (or "W") until reception
stabilizes.
When reception is complete...
• If reception was successful, the
Y (or YES)
hands will move to the correct
time. After that, the indicator hand
moves to "Y" (or "YES" for some
models). Then after about five
seconds the watch will resume
regular timekeeping.
• If the receive operation fails, the
indicator hand will move to "N" (or
30
"NO" for some models) and the
hands will move to the unadjusted
time. Then after about five
N (or NO)
seconds the watch will resume
regular timekeeping.
2. Time calibration signal reception is successful, but the
hourly time signal and current time are slightly off.
• After the watch receives the time calibration signal, it performs an
internal decoding process before updating its time setting.
Because of this, the time setting may be off slightly (within one
second).
3. Time calibration signal reception is successful, but the
current time setting is wrong.
• Are your Home Time settings configured correctly?
See "Configuring Home City Settings".
• If you cannot receive the calibration signal or if the time setting is
incorrect after signal reception, check the 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.

A A A button.
In the Timekeeping Mode, press the A A
• The indicator hand will move to "Y" (or "YES") if the last receive
operation was successful or to "N" (or "NO") if the last receive
operation was unsuccessful.
• Press the A button once to return to normal timekeeping.
• If you do not perform any operation for about five seconds, the
watch will revert automatically to normal timekeeping.

N (or NO) when not successful
The last receive status changes each time a new time
calibration signal reception operation is performed.
Calibration Signal Reception Precautions
• Auto Receive is not performed while the watch is in the Stopwatch
Mode or Alarm Mode.
• Operating any button while Auto Receive is in progress will cause
the watch to beep and then exit the receive operation.
• Make sure you are within the range of a calibration signal
transmitter before performing the receive operation. Remember
that geographic contours, nearby buildings, the season, or 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 signals transmitted in Japan, the
United States, the U.K., and Germany. Note that you will need to
make your own adjustments when using this watch outside of the
range of the time calibration signal transmitters.
• When the watch is unable to adjust its time using the calibration
signal for some reason, timekeeping accuracy is within ±15
seconds per month.
• Strong electrostatic charge can cause timekeeping error.
• Receive is cancelled if an alarm operation starts 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.
