Troubleshooting - Casio 5325 Operation Manual

To adjust home positions
1. Pull out the crown.
2. Hold down B for at least fi ve seconds until the watch beeps and the
x Second Hand moves to 12 o'clock.
 Automatic home position adjustment of all of the hands (but not the
n Day Indicator) will start.
 If all hands are at 12 o'clock (the proper home hand home position),
advance directly to step 3.
 If the v Upper Dial Hand is not pointing at 24 o'clock, which is its home
position, hold down A for about two seconds to move it there.
3. Press C.
 This enters the n Day Indicator home position adjustment mode.
4. Check the n Day Indicator to confi rm that it is 1, which is its home position.
 If the 1 is not in the center of the n Day Indicator, rotate the crown to
center it.
 Rotating the crown three full consecutive turns clockwise will cause the
n Day Indicator to start changing in a forward direction (increment).
 To stop n Day Indicator movement, press any button.
5. Push the crown back in to return to the Timekeeping Mode.
 This will cause the hands to return to their normal positions and resume
regular timekeeping. Wait until everything stops moving before performing
any other operation.
E-56
■ The current time setting is off by hours.
 Your Home City setting may be wrong. Check your Home City setting and correct it, if necessary (page
E-25).
■ 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
confi gure Home City settings" (page E-25).
 The period when summer time is applied in the location where you are using the watch may be
different from the period set for your currently selected Home City. Use the procedure under "To switch
between standard time and summer time manually" (page E-27) to switch from AUTO to STD (for standard
time) or DST (for summer time).
■ The time and date settings are off.
This could indicate that the watch has been exposed to magnetism or strong impact, which has caused
problems with proper hand and day indicator alignment. Adjust the watch's hand and day indicator home
position alignment (page E-55).
E-58
Whenever you have a sensor malfunction, take the watch to your original dealer or nearest authorized
CASIO distributor as soon as possible.
■ What causes incorrect direction readings?
 The watch may have been exposed to magnetism. Calibrate the direction sensor.
 A nearby source of strong magnetism, such as a household appliance, a large steel bridge, a steel
beam, overhead wires, etc., or an attempt to perform direction measurement on a train, boat, etc. Move
away from such objects and try again.
■ What causes different direction readings to produce different results at the same location?
 Magnetism generated by nearby digital noise sources (such as high-tension power lines) can interfere
with the detection of terrestrial magnetism. Move away from the source of the digital noise and try
again.
■ Why am I having problems taking direction readings indoors?
A TV, personal computer, speakers, or some other object is interfering with terrestrial magnetism
readings. Move away from the object causing the interference or take the direction reading outdoors.
Indoor direction readings are particularly diffi cult inside ferro-concrete structures. Remember that you will
not be able to take direction readings inside of trains, airplanes, etc.
Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3 (page E-12). Continue exposing the watch to light until
the x Second Hand starts moving normally (at one-second intervals).
E-60
■ The current time setting changes after I set it manually.
You may have the watch confi gured for Auto Receive of the time calibration signal (page E-18), 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-25).
■ The current time setting is off by one hour.
Possible Cause
The period when summer time is applied in the
location where you are using the watch may be
different from the period set for your currently
selected Home City.
■ Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause
The watch is in the World Time Mode.
The watch is in the Stopwatch Mode.
Your Home City setting is wrong.
Auto time calibration signal reception is OFF.
A direction reading or countdown timer operation
is in progress.
There is not enough power for signal reception.
E-62
Operation Guide 5325
Remedy
Use the procedure under "To switch between
standard time and summer time manually" to switch
from AUTO to STD (for standard time) or DST (for
summer time).
Remedy
Auto Receive is not performed while the watch
is in the World Time Mode or Stopwatch Mode.
Hold down C at least two seconds to enter the
Timekeeping Mode.
Check your Home City setting and correct it, if
necessary.
Check the auto time calibration signal reception
setting.
Stop the ongoing operation.
Expose the watch to light to charge it.

Troubleshooting

Hand Movement and Position
■ I lost track of what mode the watch is in.
Refer to "Mode Reference Guide" (page E-22). To return directly to the Timekeeping Mode, hold down C at
least two seconds.
■ The x Second Hand is moving at two-second intervals.
■ All the watch's hands are stopped at 12 o'clock and none of the buttons work (x Second Hand
stopped at 57, 58, 59, or 00).
Power may be low. Expose the watch to light until the x Second Hand starts moving normally, at one-
second intervals (page E-12).
■ The hands of the watch suddenly start moving at high speed, even when I do not perform any
operation.
This could be due to any one of the following causes. In all cases, the hand movement does not indicate
malfunction, and should stop shortly.

The watch is recovering from a sleep state (page E-14).
 The time setting is being adjusted following a successful auto time calibration signal receive operation
(page E-15).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-13). Do not perform any operation until the hands
return to their normal positions (in about 15 minutes). The hands should return to their correct positions
when normal operation returns. To help power recover, leave the watch in a location where it is exposed
to light.
Sensor modes
■ An error is indicated during sensor operation.
Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal
circuitry. When this happens an error is indicated and the sensor operation cannot be performed. The
illustrations below how sensor mode errors are indicated.
 During digital compass operations, nearby strong magnetism can cause an
Digital Compass Mode
error to be indicated.
 If the error is indicated during a measurement, restart the measurement. If
an error is indicated when you restart the measurement, it probably means
that there is a problem with the sensor or internal circuitry.
■ Abnormal magnetism detection is indicated.
 Move the watch away from magnetic accessories, electric devices,
computers, and any other devices that generate strong magnetism, and try
performing the sensor operation again.
 If abnormal magnetism detection is indicated again, it may mean that the
watch case may have become magnetized or that magnetism conditions
are completely different from those where you last performed bidirectional
calibration. Perform bidirectional calibration using the procedure under "To
perform bidirectional calibration" (page E-37).
■ The x Second Hand starts to move at one-second intervals, but then suddenly returns to moving
at two-second intervals.
The watch probably is not suffi ciently charged yet. Continue keeping it exposed to light.
Time Calibration Signal
The information in this section applies only when LONDON (LON), PARIS (PAR), ATHENS (ATH),
HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX), DENVER (DEN), CHICAGO (CHI),
NEW YORK (NYC), HONG KONG (HKG), or TOKYO (TYO) is selected as the Home City. You need to
adjust the current time manually when any other city is selected as the Home City.
■ The x Second Hand indicates NO (N) when I check the result of the latest receive operation.
Possible Cause
 You are wearing or moving the watch, or
performing a button operation during time
calibration signal receive operation.

The watch is in an area with poor reception
conditions.
You are in an area where signal reception is not
possible for some reason.
The alarm time was reached during time calibration
signal reception.
The calibration signal is not being transmitted for
some reason.
■ Signal reception is being performed successfully, but the time and/or day is wrong.
Possible Cause
Your Home City setting is wrong.
The watch may have been exposed to magnetism
or strong impact, which has caused problems with
Page
proper hand and day indicator alignment.
E-27
World Time
■ The indicated World Time is wrong.
There is a problem with your Home City settings.
Check your Home City settings.
See "To confi gure Home City settings" (page E-25).
Page
■ The indicated World Time is one hour off.
E-18
The daylight saving time (summer time) setting for the World Time city is wrong.
E-23
See "To view the time in another time zone" (page E-43).
E-15
Alarm
E-25
■ The alarm does not sound.
E-20
 Power may be low. Expose the watch to light until the x Second Hand starts moving normally, at one-
second intervals (page E-12).
E-32
 The time setting is wrong in terms of a.m. and p.m.
E-49
 The crown may be pulled out. Push the crown back in.
E-10
Remedy
Keep the watch in an area where reception
conditions are good while time calibration signal
receive operation is being performed.
See "Approximate Reception Ranges".
The alarm sounded during time calibration signal
reception, causing reception to be canceled.
 Check the website of the organization that
maintains the time calibration signal in your area
for information about its down times.
 Try again later.
Remedy
Check your Home City setting and correct it, if
necessary.
Adjust the watch's hand and day indicator home
positions.
