TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS  
USING THE CLOCK  
This clock is able to receive the time calibration signal transmitted from  
Mainflingen, Germany (located 25kilometers southeast of Frankfurt).  
Signal reception is possible within approximately 1,200 km of the  
transmitter.  
Even when the clock is within the reception range, signal reception may  
be impossible if the signal is blocked by mountains or other geological  
formations between the clock and signal source.  
Any of the following procedures can be used to set current date and time.  
Auto receive of the time calibration signal  
Mainflingen  
Manual receive of the time calibration signal  
1200 km  
Manual setting without using the time calibration signal  
Auto Receive  
The clock receives the time calibration signal eight times each day (2:00, 5:00, 8:00, 11:00, 14:00, 17:00, 20:00,  
23:00).  
Signal reception is affected by weather, atmospheric conditions, and  
seasonal changes.  
A signal receive operation takes from two to ten minutes under good signal conditions.  
The time calibration signal bounces 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 toward  
Mainflingen. Note, however, that moving the clock while the time  
calibration signal receive operation is taking place will make stable  
reception impossible.

Wave OK Indicator  
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.  
If you see this:  
OK is not displayed.  
It means this  
All receive operations over the past 24 hours failed, or signal  
reception is in progress.  
OK is displayed.  
At least one of the receive operations over the past 24 hours was  
successful.  
Unsuccessful Signal Reception  
The antenna icon disappears from the display when a signal receive operation is unsuccessful. If this happens,  
try changing the position or orientation of the clock, and press the WAVE button (3) to receive again.

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.

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.

Setting the Time and Date Manually  
BATTERY REPLACEMENT  
When using the clock in an area that is outside of the range of the transmitter in Mainflingen or in an area where  
signal reception is impossible for some reason, you need to manually adjust the time as required.  
1. Press the SET button (2) to cycle through the setting screens as shown below.  
Low Battery Warning  
Note that the indicator appears on the main unit display when sub-unit battery power goes low.  
Replace the batteries as soon as possible.  
Normal Timekeeping Screen  
To replace main unit batteries  
Replace batteries whenever the display of the clock becomes dim and difficult to read.  
1. Open the battery compartment cover as shown in the illustration.  
2. Remove all of the old batteries.  
3. Load a full set of new batteries. Make sure that their positive (+) and negative () ends face in the correct

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 product.  
Should batteries ever leak while in the product, 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 product lose some of their power during transport and storage.  
2. While the screen you want is on the display, use the Time Setting buttons (1) to change the digits that are  
flashing.

Both the main unit and the sub-unit are equipped with their own temperature sensors. Temperature data measured  
by the sub-unit is sent by wireless transfer to the main unit. You can toggle the main unit display between the main  
unit temperature reading and the sub-unit temperature reading. This makes it possible to view both the indoor and  
outdoor temperature on the main unit display.  
Holding down + or changes the flashing digits at high speed.  
You can set the year in the range of 2000 to 2039. The day of the week is set automatically in accordance with  
the date setting.  
Temperature Measurements  
Pressing + or while the Time Setting Screen is on the display causes the seconds count to be reset to 00.  
Each press of + or while the 12-hour/24-hour Timekeeping Screen is on the display toggles between 12-hour  
and 24-hour timekeeping.  
Both the main unit and the sub-unit take temperature measurements every 16 seconds.  
The temperature display shows LOfor temperatures below 50°C (58°F) and HIfor temperatures above  
70°C (158°F).  
Though temperature readings are displayed up to 0°C (32°F) and greater than 41°C (105°F), note that such  
readings are actually outside the guaranteed temperature range of this clock.  
3. After configuring the settings you want, use the SET button (2) to display the Normal Timekeeping Screen.  
The clock automatically returns to the Normal Timekeeping Screen if you leave a setting screen on the display for  
about three minutes without performing any operation.

If a receive operation is not successful for some reason, the display of the main unit shows dashes () in place of  
the sub-unit temperature and humidity values.  
If you experrience problems with data transfer, press the RE-SYNC button (6) to synchronize the two units. If  
this does not eliminate the problem,try changing the positions or orientations of the main unit and sub-unit.  
The transferred data includes temperature and humidity data.

MAIN UNIT/SUB UNIT COMMUNICATION PRECAUTIONS  
Sub Unit Location  
Certain environmental conditions can greatly reduce the communication range.  
Avoid the following locations for the sub-unit.  
Inside or among  
buildings, or near  
neon signs  
Inside a vehicle  
Near refrigerators  
Near a  
Near high-tension  
power lines  
or other household construction site,  
appliances, near  
office equipment,  
mobile phones or  
wireless LAN  
devices  
airport, or other  
sources of  
electrical noise,  
underground or in
