Radio Controlled Atomic Timekeeping; Mode Reference Guide - Casio 5114 Operation Manual

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" 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)
HONOLULU (HNL), ANCHORAGE (ANC),
LOS ANGELES (LAX), DENVER (DEN), CHICAGO (CHI),
NEW YORK (NYC)
Important!
• The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration
signal transmitters, so certain conditions may cause reception problems.
• When HONG KONG (HKG) is selected as the Home City, only the time and date are adjusted
according to the time calibration signal. You need to switch manually between standard time and
daylight saving time (DST) if required. See "To confi gure Home City settings" for information about how
to do this.

• 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 January 2009, 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.
• Using this watch in a country covered by a time calibration that is different from the countries it
supports may result in incorrect time indication due to local application of summer time, etc.
To get ready for a receive operation
1. Confi rm that the watch is in the Timekeeping Mode. If it isn't, hold down D for about two seconds to
enter the Timekeeping Mode.
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.

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".
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 or World Time Mode. The receive operation is not performed if a calibration time is
reached while you are confi guring settings.
• You can use the procedure under "To turn auto receive on and off" to enable or disable auto receive.

• Signal reception normally is better at night.
• The receive operation takes from two to seven minutes, but
in some cases it can take as long as 14 minutes. Take
care that you do not perform any button operation or
move the watch during this time.

Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time setting.
• Even if a receive operation is successful, certain conditions can cause the time setting to be off by up
to one second.
• The watch is designed to update the date and day of the week automatically for the period January 1,
2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed
starting from January 1, 2100.
• If you are in an area where signal reception is not possible, the watch keeps time with the precision
noted in "Specifi cations".
• The receive operation is disabled under any of the following conditions.
– While power is at Level 3 (L) or lower
– While the watch is in the power recovery mode
– While a sensor operation is being performed
– When the watch is in the function sleep state ("Power Saving")
– While a hand home position adjustment operation is in progress
– While a countdown timer operation is in progress
• A receive operation is cancelled if an alarm sounds while it is being performed.
• The Home City setting reverts to the initial default of TOKYO (TYO) whenever the battery power level
drops to Level 5 or when you have the rechargeable battery replaced. If this happens, change the
Home City to the setting you want.

Mode Reference Guide

Your watch has 11 "modes". The mode you should select depends on what you want to do.
To do this:
• View the current date in the Home City
• Confi gure Home City and daylight saving time (DST) settings
• Confi gure time and date settings manually
• Determine your current bearing or the direction from your current
location to a destination as a direction indicator and angle value
• Determine your current location using the watch and a map
• View the barometric pressure and temperature at your current location
• View a graph of barometric pressure readings
• View the altitude at your current location
• Determine the altitude differential between two locations (reference
point and current location)
• Record an altitude reading with the measurement time and date

• Perform a time calibration receive operation
• Check whether the last receive operation was successful
Perform hand home position adjustment
1. Use D to select the Receive Mode (RC) as shown in "Selecting a
Mode".
2. Hold down A until the second hand points to READY (or R on some
models).
• This indicates that the watch is ready for signal reception.
• After a short while, the second hand will move to WORK (or W on
some models) and signal reception will begin. Do not operate
any of the watch's buttons until the second hand starts moving
normally again, which indicates that reception is complete.
• If signal reception is unstable, the second hand may keep moving
between WORK (W) and READY (R).
• OK will appear on the digital display if the receive operation is
successful, while Err indicates reception was unsuccessful.
• If the second hand remains at READY (R), press any button to cancel
signal reception. Move the watch to a location where reception
conditions are better and try again.
3. Press D twice to return to the Timekeeping Mode.
Note
To cancel an ongoing signal receive operation, press any of the watch's
buttons. This will return to the Receive Mode screen in step 1 of this
procedure.
Enter the Receive Mode.
• When receive is successful, the digital display shows the time and
date that receive was successful. - : - - indicates that none of the
reception operations were successful.
