HOW TO INSTALL AND REPLACE BATTERIES IN THE OUTDOOR THERMO-
HYGRO TRANSMITTER
The outdoor Thermo-hygro transmitter uses 2 x AA IEC LR6, 1.5V batteries. To
install and replace the batteries, please follow the steps below:
1. Remove the battery cover at the front side with a small screwdriver.
2. Insert the batteries, observing the correct polarity (see battery
compartment marking).
3. Replace the battery cover on the unit.
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 because a random security code is assigned by the transmitter at
start-up and this code must be received and stored by the Weather Station in the first 3 minutes
of power being supplied to it.

BATTERY CHANGE:

It is recommended to replace the batteries in all units on an annual basis to ensure optimum
accuracy of these units.
Please participate in the preservation of the environment. Return used batteries
to an authorised depot.
DCF-77 RADIO CONTROLLED TIME RECEPTION:
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 Weather Station 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 1,500km radius around Frankfurt.
After the temperature and humidity reception is completed in initial setup, the DCF tower icon in
the clock display will start flashing in the upper right corner of the first section of the LCD. This
indicates that the clock has detected the presence of a radio signal and is trying to receive it.
When the time code is received, the DCF tower becomes permanently lit and the radio-
controlled 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.
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
battery compartment marking).
3. Replace battery cover.
