Troubleshooting - Casio 5477 Operation Manual

■ The watch won't enter the Timekeeping Mode.
If you accidentally enter the Depth Meter Mode while in an aircraft or any other vehicle where there are
large changes in air pressure, the watch will interpret the current pressure as being underwater (depth of
1.0 meters or greater). In this condition, the watch will not return to the Timekeeping Mode.
If this happens, hold down B for about two seconds to force the watch to return to the Timekeeping
•
Mode.
■ The warning mark ( ! ) is fl ashing on the display.
Refer to "Troubleshooting when a Flashing Warning Mark ( ! ) Appears" (page E-86).
■ Depth readings are incorrect.
When the watch enters the Depth Meter Mode, it sets the current ambient pressure as 0 meters. Because
of this, you should always enter the Depth Meter Mode while on the water surface. If you entered the
Depth Meter Mode while under water, reset 0 meters on the water surface.
Especially during the summer months, direct sunlight can cause the watch to become abnormally hot. If
this happens, leave the watch in the water for two to three minutes to acclimate before using it.
Subjecting the watch to strong shock can affect the accuracy of the depth measurements. If this happens
immediately contact an authorized CASIO service center for inspection and sensor adjustment.
This watch displays sea water depth. Fresh water depth can be obtained by multiplying the displayed
depth value by 1.025.
Barometric Pressure, Bearing, Altitude, Temperature, and Depth Readings
■ ERR appears on the digital display during sensor reading operations.
This indicates that there is a problem with the sensor, making sensor readings impossible.
• If the error is indicated while a reading operation in progress, restart the operation. If ERR appears
again, it could mean there is something wrong with the sensor.
E-120
Note
• Performing repeated illumination and/or sensor reading operations over a short time period can cause
a sudden drop in watch's charge. This will cause the watch to enter the charge recovery mode. The
watch is in the charge recovery mode when RECOVER is fl ashing on the digital display. The charge
recovery mode is the same as a low battery charge state, access to some functions is limited while the
watch charge is recovering. Normal operation will resume after recovery is complete. For more
information, refer to "Power Recovery Mode" (page E-17).
• A fl ashing CHARGE indicator means that the charge level of the watch has suddenly dropped.
Immediately expose the watch to light to charge it.
Time Calibration Signal

HKG, BJS, HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI, NYC, YHZ, YYT, TPE, SEL, or 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.

• If ERR appears frequently, it could mean that the sensor is faulty. Contact your original retailer or
CASIO service center.
■ I can't change the temperature, barometric pressure, and altitude display units.
When TYO (Tokyo) is selected as the Home City, the altitude unit is set automatically to meters (m), the
barometric pressure unit to hectopascals (hPa), and the temperature unit to Celsius (°C). These settings
cannot be changed.
World Time Mode
■ The time for my World Time City is off in the World Time Mode.
This could be due to incorrect switching between standard time and daylight saving time. See "To
confi gure World Time City and summer time settings" (page E-93) for more information.
Charging
■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 5 (page E-15). Keep the watch exposed to light until it
recharges suffi ciently.
■ RECOVER is fl ashing on the digital display.
The watch is in the charge recovery mode. Wait until the recovery process is complete (about 15 minutes).
The watch will recover more quickly if you place it in a brightly lit location.

■ 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-23), 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-34).
