TIME CALIBRATION SIGNAL RECEPTION PRECAUTIONS
• This clock is able to receive the time calibration signal transmitted from
Mainflingen, Germany (located 25kilometers southeast of Frankfurt).
Mainflingen
Signal reception is possible within approximately 1,200 km of the
1200 km
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
atmosaheric 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
500 km
Mainflingen. 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.

Near a
Near high-tension
construction site, power lines
airport, or other
sources of
electrical noise,
underground or in
tunnels, near
railroads,
highways, or radio
stations with
interfering
frequencies.

Among or behind
mountains

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.
The alarm does not operate during signal reception.

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

• 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).
• A signal receive operation takes from two to ten minutes under good signal conditions.
• A receive indicator shows the current status of the receive operation.

Receive in progress: Icon flashes
Receive failed: Icon not displayed
Receive successful: Icon displayed

Wave OK Indicator
Receive in Progress: OK not displayed
All receives over the past 24 hours failed: OK not displayed
At least one successful receive over the past 24 hours: OK displayed

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 (4) to receive again.

Manual Receive

• Press the WAVE button (4) to start a calibration signal receive operation.
• Use the WAVE button (4) 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 clock beeps and display illumination flashes for about three seconds when a receive operation trigged by the
WAVE button (4) 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.

BATTERY REPLACEMENT
High Temperature and Low Temperature Memory

Low Battery Warning
A
indicator appears on the display to let you know when battery power is low. Replace the batteries as soon
as possible.
Note that the
indicator appears on both the main unit and sub-unit when sub-unit battery power goes low.

• The following data is stored in memory automatically.
Main unit high temperature and low temperature
Sub-unit high temperature and low temperature

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
directions. If you load batteries incorrectly, they can burst and damage the clock.
4. Replace the battery compartment cover.
5. Press the RESET button (6). Be sure to press the RESET button (6) after replacing batteries.

Current temperature

To replace sub-unit batteries
1. Rotate the battery compartment cover from LOCK to OPEN.
2. Remove both old batteries.
3. Load 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. Replace the battery compartment cover.
5. Press the RESET button (B). Be sure to press the RESET button (B) after replacing batteries.
6. Press the RE-SYNC button (0).

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.

Sub-unit high temperature and low temperature

THERMOMETER FUNCTIONS
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. This makes it possible to view both the indoor and
outdoor temperature on the main unit display.

• To clear the high temperature and low temperature data memory, press the CLEAR button (8).
New data starts to be stored after memory is cleared.

Temperature Measurements

• Both the main unit and the sub-unit take temperature measurements every 16 seconds.
• The temperature display shows “LO” for temperatures below –50°C (–58°F) and “HI” for 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.

Switching between Celsius and Fahrenheit
• Push the °C/ °F button (9) to select either Celsius (°C) or Fahrenheit (°F).

USING THE SUB-UNIT
Data Transfer from the Sub-unit
• Data is transferred from the sub-unit to the main unit every three minutes.
• The sub-unit is able to send data to the main unit up to an unobstructed distance of about 30 meters.
• The data receive status is indicated on the display of the main unit by the icons shown below.
Receive successful

Receive unsuccessful

• 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 value.
• If you experience problems with data transfer, press the RE-SYNC button (0) 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.

Switching between Celsius and Fahrenheit

• Push the °C/ °F button (A) to toggle between Celsius (°C) and Fahrenheit (°F).
