    TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS•This clock can receive the time calibration signals transmitted from
    Mainflingen, Germany and Rugby, England. It automatically selects
    reception from the transmitter whose signal is strongest.
    Mainflingen: Signal reception is possible within approximately 1800 km
    of the transmitter.
    Rugby: Signal reception is possible within approximately 1800 km of the
    transmitter.
    •Even when the clock is within the reception range, signal reception is
    impossible if the signal is blocked by mountains or other geological
    formations between the clock and signal source.
    •Signal reception is affected by weather, atmospheric conditions, and
    seasonal changes.
    •The time calibration signal is bounced off the ionosphere. Because of
    this, such factors as changes in the reflectivity of the ionosphere, as well
    as movement of the ionosphere to higher altitudes due to seasonal
    atmospheric changes or the time of day may change the reception range
    of the signal and make reception temporarily impossible.
    •Reception is best when the back of the clock is facing in the direction of the transmitter. As a general rule, point
    the back of the clock towards the transmitter that is closest to your location. If you experience reception problems,
    try pointing it in the direction of the other transmitter. Note, however, that moving the clock while the time
    calibration signal receive operation is taking place will make stable reception impossible.
    •Think of the clock as acting like a TV or radio when it is receiving the calibration signal. When receiving indoors,
    move to a location as near as possible to a window. Proper signal reception can be difficult or even impossible
    under the conditions listed below.
    •Signal reception is normally better at night than during the day.
    •Radio interference can make signal reception impossible.
    •Strong electrostatic charge can result in the wrong time being set.
    USING THE CLOCK 1This clock can receive the time calibration signals transmitted from Mainflingen, Germany and Rugby, England.
    It automatically selects reception from the transmitter whose signal is strongest.
    Any of the following procedures can be used to set current date and time.
    •Auto receive of the time calibration signal
    •Manual receive of the time calibration signal
    •Manual setting without using the time calibration signal
    Auto Receive•This clock performs a 1-minute receive operation each hour.
    •A signal receive operation takes from two to fourteen minutes under good signal conditions.
    •As the clock receives a time calibration signal, current signal strength is indicated by the receive indicator, which
    is a horizontal line above the current time.
    •A longer receive indicator line means better signal reception.
    Antenna IconThe antenna icon appears when at least one signal receive operation is successful during a day. The antenna
    icon is cleared at 2 a.m. and 3 a.m. each day, and will reappear as soon as a subsequent signal receive
    operation is successful.
    Wave OK IndicatorThe Wave OK indicator is displayed when there has been a successful receive operation within the last hour.
    This indicator disappears at the top of each hour, or when you perform a manual receive operation.
    Unsuccessful Signal ReceptionThe antenna icon disappears from the display if no signal receive operation is successful during a continuous
    24-hour period. If this happens, try changing the position or orientation of the clock, and press the WAVE button
    (8) to receive again.
    Manual Receive•Press the WAVE button (8) to start a calibration signal receive operation.
    •Use the WAVE button (8) to perform a receive operation after replacing the clock’s batteries or if the auto receive
    operation was not performed correctly for some reason.
    •The antenna icon appears when signal reception triggered by the WAVE button (8) is successful.
    Important!•Do not perform any button or switch operation while a signal receive operation is in progress.
    •The time calibration signal includes both Standard Time and Daylight Saving Time (summer time) data.
    •The DST indicator appears on the display when Daylight Saving Time (summer time) data is received.
    •Note that Daylight Saving Time (summer time) is turned on and off in accordance with the received time
    calibration signal only. You cannot turn it on or off manually.

    USING THE CLOCK 2
    Setting the Time and Date Manually•When using the clock in an area that is outside of the range of the transmitter or in an area where signal
    reception is impossible for some reason, you need to manually adjust the time setting as required.
    1. Press the SET button (6) to cycle through the setting screens as shown below.

    Your GMT differential is a value that indicates the time
    difference between your current location and Greenwich
    Mean Time (GMT). You can find out the GMT differential
    of your location by checking the nearby map.

    •Press the SIG button (5) to toggle the Hourly Time Signal on and off.
    •The SIG indicator indicates that the Hourly Time Signal is turned on.
    THERMOMETER FUNCTIONS•A built-in sensor measures temperature and shows the measured value on the display.
    •The displayed temperature is replaced by “LO” for temperatures –20.0°C (–4.0°F) and lower,  and “HI” for
    temperatures 50.0°C (122.0°F) and higher.
    •Though temperature readings are displayed up to 0°C (32°F) and greater than 40.1°C (104.1°F), note that such
    readings are actually outside the guaranteed temperature range of this clock.
    Switching between Celsius and Fahrenheit•See “Setting the Time and Date Manually” for information about selecting Celsius (°C) or Fahrenheit (°F) as the
    temperature unit.
    High Temperature and Low Temperature Memory•The following data is stored in memory automatically.
    Current Temperature
    MAX/MIN button (   )High Temperature
    Low Temperature
    •Holding down the MAX/MIN (2) button for about two seconds starts auto display, which cycles automatically
    between the current, high, and low temperatures. To exit auto display, press the MAX/MIN button (2) again.
    •High temperature and low temperature memory is cleared each day at midnight.
    USING THE LIGHTPressing the SNOOZE/LIGHT button (1) turns on the light and illuminates the display for easy reading in the dark.Important!•Overuse of the light can shorten battery life.
    BATTERY REPLACEMENTReplace batteries whenever the display of the clock becomes dim and difficult to read.
    1. Pressing down lightly on the battery compartment cover, slide it downwards and remove it.
    2. Remove both of the old batteries.
    3. Load two new batteries. Make sure that their positive (+) and negative (–) ends face in the correct directions. If
    you load batteries incorrectly, they can burst and damage the clock.
    4. Press the RESET button (7). Be sure to press the RESET button (7) after replacing batteries.
    5. Replace the battery compartment cover.
    Battery precautions•Keep batteries out of the reach of small children. If a battery is accidentally swallowed, contact your physician
    immediately.
    •Be sure to load the batteries with their positive (+) and negative (–) ends facing correctly.
    •Never mix old and new batteries, or batteries of different brands.
    •Never charge the batteries that come with the clock.
    •
    Should batteries ever leak while in the clock, wipe out the fluid with a cloth, taking care not to let any get onto your skin.•Replace the batteries at least once a year, even if the current batteries are working properly.
    •The batteries that come with the clock lose some of their power during transport and storage.
