TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE
TRANSMITTER

The transmitter uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the batteries, please
follow the steps below:

1. Remove the cover.

2. Insert the batteries, observing the correct polarity (see battery compartment marking).

3. Replace the battery cover on the unit.

Alkaline batteries are recommended for use in both units. Avoid using rechargable
batteries.

TO INSTALL AND REPLACE BATTERIES IN THE MOONPHASE WALL CLOCK

The moonphase wall clock uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the
batteries, please follow the steps below:

1. Insert finger or other solid object in the space at the bottom center of the battery
compartment and lift up to remove the cover.

2. Insert batteries observing the correct polarity (see marking inside battery compartment).

3. Replace compartment cover.

DO NOT SET THE CLOCK.

Battery replacement

• Replace the batteries of the clock when the battery symbol RX appears near the time

display.

• When the batteries of the transmitter are used up, the low battery icon TX appears near the

moon phase icon.

Note:

In the event of changing batteries in any of the units, all units need to be reset by following the
setting up procedures. This is due to a random security code assigned by the transmitter at start­up. This code must be received and stored by the moonphase wall clock
power being supplied to the transmitter.

in the first 3 minutes of

SETTING UP:

1. Insert the 2 x AA, IEC LR6, 1.5V batteries into the transmitter (See “To install and
replace batteries in the temperature transmitter” above).

2. Within 3 minutes, insert 2 x AA, IEC LR6, 1.5V batteries into the moonphase wall clock as
indicated above (see "To install and replace batteries in the moonphase wall clock“
above).

3. Once the batteries are in place, all segments of the LCD will light up briefly. Then the
indoor and outdoor temperature - -.-°C, the time as 0:00, the date as 1/1, and weekday will
be displayed.

4. Do not press any buttons for 10 minutes

5. The moonphase wall clock will start receiving data from the transmitter. The remote
temperature will then be displayed on the Moonphase wall clock. If the outdoor
temperature is not displayed 90 seconds after inserting the batteries into the receiver, all
batteries are needed to be removed and wait for at least 1 minute for reset from step 1.

6. The DCF time code reception will automatically start. This takes typically between 3 - 5
minutes in good conditions. This time period is an excellent opportunity to locate the

19

transmitter in suitable location outdoors. In order to ensure sufficient 868MHz transmission
however, this should under good conditions be no more than 100 meters from where the
Moonphase wall clock will be finally positioned (see notes on “Positioning” and “868MHz
Reception”).

7. If after 10 minutes the DCF time has not been received, use the SET key to manually enter
the set mode and change either the time or date in order to activate the DCF reception.
When this is successful, the received time will override the manually set time. The date is
also updated with the received time (Please refers to notes on “DCF Radio controlled

time” and “Manual time setting”).

DCF RADIO CONTROLLED TIME

The time base for the radio controlled time is a Cesium Atomic Clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of less than
one second in one million years. The time is coded and transmitted from Mainflingen near
Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately
1,500 km. Your radio-controlled moonphase wall clock receives this signal and converts it to
show the precise time in summer or wintertime.
The quality of the reception depends greatly on the geographic location. In normal cases, there
should be no reception problems within a 1500km radius of Frankfurt.

DCF reception is done twice daily at 02:00 and 03:00 am. If the reception is not successful at
03:00 am, then the next reception takes place the next hour and so on until 06:00am, or until the
reception is successful. If the reception is not successful at 06:00 am, then the next attempt will
take place the next day at 02:00 am.

Once the outdoor data reception test period is completed, the DCF tower icon in the clock
display will start flashing in the upper left corner. This indicates that the clock has detected that
there is a radio signal present and is trying to receive it. When the time code is received, the
DCF tower becomes permanently lit and the time will be displayed.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, then
please take note of the following:

• Recommended distance to any interfering sources like computer monitors or TV sets is a

minimum of 1.5 - 2 meters.

• Within ferro-concrete rooms (basements, superstructures), the received signal is naturally

weakened. In extreme cases, please place the unit close to a window and/ or point its front
or back towards the Frankfurt transmitter.
