To Recover From The Sleep State - Casio 5463 Operation Manual

Power Recovery Mode
• Performing multiple sensor, illumination, or beeper operations during a short period may cause the
recovery indicator (RECOVER) to start fl ashing on the display. This indicates that the watch is in the
power recovery mode. Illumination, alarm, countdown timer alarm, hourly time signal, and sensor
operations will be disabled until battery power recovers.
• Battery power will recover in about 15 minutes. At this time, the recovery indicator (RECOVER) will stop
fl ashing. This indicates that the functions listed above are enabled again.
• Frequent fl ashing of the recovery indicator (RECOVER) indicates that battery power is low. Expose the
watch to bright light as soon as possible.
• Even if battery power is at Level 1 (H) or Level 2 (M), the Digital Compass Mode, Barometer Mode,
Thermometer Mode or Altimeter Mode sensor may be disabled if there is not enough power available
to power it suffi ciently. This is indicated when the recovery indicator (RECOVER) are fl ashing.
• Frequent fl ashing of the recovery indicator (RECOVER) probably means that remaining battery power
is low. Leave the watch in bright light to allow it to charge.

Power Saving
When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain
period in an area where it is dark. The table below shows how watch functions are affected by Power
Saving.
• For information about enabling and disabling power saving, see "To turn Power Saving on or off" (page
E-99).
• There actually are two sleep state levels: "display sleep" and "function sleep".

• The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep
state when 6:00 AM arrives, however, it will remain in the sleep state.
• The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode.
• The watch will not enter a sleep state while barometric pressure change indicator is enabled (page
E-73).

To recover from the sleep state

Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading (page
E-96).

3. What you should do next depends on whether you are using auto receive or manual receive.
• Auto receive: Leave the watch over night in the location you selected in step 2. See "Auto Receive"
below for details.
• Manual receive: Perform the operation under "To perform manual receive" on page E-23.
Auto Receive
• With auto receive, the watch performs the receive operation each day automatically up to six times (up
to fi ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to
the Timekeeping Mode time). When any receive operation is successful, none of the other receive
operations for that day are performed.
• When a calibration time is reached, the watch will perform the receive operation only if it is in the
Timekeeping Mode. The receive operation is not performed if a calibration time is reached while you
are confi guring settings.

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. However, when
using the watch outside of areas covered by time calibration signals, you will have to adjust the settings
manually as required. See "Confi guring Current Time and Date Settings Manually" (page E-36) for more
information.
This section explains how the watch updates its time settings when the city code selected as the Home
City is in Japan, North America, Europe, or China, and is one that supports time calibration signal
reception.
If your Home City Code setting is this:
LONDON (LON), PARIS (PAR), ATHENS (ATH)
HONG KONG (HKG)
TOKYO (TYO)
NEW YORK (NYC), CHICAGO (CHI), DENVER (DEN), LOS
ANGELES (LAX), ANCHORAGE (ANC), HONOLULU (HNL)
Important!
• The areas covered by ANC and HNL are quite far from the calibration signal transmitters, so certain
conditions may cause reception problems.
• Even when the watch is within range of a transmitter, signal reception may be impossible due to the
effects of geographic contours, structures, weather, the time of year, the time of day, radio interference,
etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the
infl uence of the conditions listed above becomes even greater.
• Signal reception may not be possible at the distances noted below during certain times of the year or
day. Radio interference may also cause problems with reception.
Mainfl ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
Shangqiu (China) transmitter: 500 kilometers (310 miles)
• As of December 2014, China does not use Daylight Saving Time (DST). If China does go to the Daylight
Saving Time system in the future, some functions of this watch may no longer operate correctly.
To get ready for a receive operation
1. Confi rm that the watch is in the Timekeeping Mode. If it isn't, use B to enter the Timekeeping Mode
(page E-30).
2. The antenna of this watch is located on its 12 o'clock side. Position the watch with 12 o'clock facing
towards a window as shown in the nearby illustration. Make sure there are no metal objects nearby.

• A signal level indicator (L1, L2, or L3, see page E-25) will appear
on the display after reception starts. Do not allow the watch to
move and do not perform any button operation until GET or ERR
appears on the display.
• If the receive operation is successful, the reception date and time
appear on the display, along with the GET indicator.
• The watch will immediately return to the Timekeeping Mode if you
