HOW TO INSTALL AND REPLACE BATTERIES IN THE

TEMPERATURE TRANSMITTER

The temperature transmitter uses 2 x AA, IEC LR6, 1.5V

battery. To install and replace the batteries, please follow

the steps below:

1. Remove the battery compartment cover at the back

of the transmitter.

Foldout stand

Battery

compartment

cover

Hanging hole

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

3. Replace the battery compartment cover on the unit.

HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER

STATION

The weather station uses 3 x AA, IEC LR6, 1.5V batteries. When batteries will

need to be replaced, the low battery

icon will appear on the LCD. To install

and replace the batteries, please

follow the steps below:

1. Lift up the battery compartment

cover.

2. Insert batteries observing the

correct polarity (see marking).

3. Replace compartment cover.

Battery replacement

Replace the batteries when the battery symbol of the weather station

appears above the indoor temperature.

When the batteries of the transmitter are used up, the low battery icon

appears above the outdoor temperature display.

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 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.

SETTING UP:

Note: This weather station receives only one outdoor transmitter.

1. First, insert the batteries into the Temperature transmitter. (see “Install

and replace batteries in the temperature transmitter“).

2. Immediately after and within 30 seconds, insert the batteries into

Weather station (see “Install and replace batteries in the weather

station”). Once the batteries are in place, all segments of the LCD will

light up briefly. Following the time as 0:00 and the weather icon will be

displayed. If these are not displayed after 60 seconds, remove the

batteries and wait for at least 30 seconds before reinserting them.

3. After inserting the batteries, the Weather station will start receiving data

from the transmitter. The outdoor temperature and the signal reception

icon should then be displayed on the Weather station. If this does not

happen after 3 minutes, the batteries will need to be removed from both

units and reset from step 1.

4. In order to ensure sufficient 868 MHz transmission however, this should

under good conditions be a distance no more than 100 meters between

the final position of the weather station and the transmitter (see notes on

“Mounting” and “868 MHz Reception”).

5. Once the remote temperature has been received and displayed on the

weather station, the DCF time (radio controlled time) code reception is

automatically started. This takes typically between 3-5 minutes in good

conditions.

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 weather station receives this signal and converts it to show the

precise time in summer or wintertime.

SET key

The quality of the reception depends greatly on the geographic location. In

normal cases, there should be no reception problems within a 1,500 km 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.

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.

During nighttime, the atmospheric disturbances are usually less severe

and reception is possible in most cases. A single daily reception is

adequate to keep the accuracy deviation below 1 second.

the snooze function. The alarm will stop and re-activate after the snooze

interval of 10 minutes.

2. To stop the alarm completely, press any keys other than the MIN/MAX

RESET key.

WEATHER FORECAST AND TENDENCY

THE WEATHER FORECASTING ICONS :

There are 3 weather icons in the second section of LCD which can be

displayed in any of the following combinations :

For every sudden or significant change in the air pressure, the weather icons

will update accordingly to represent the change in weather. If the icons do not

change, then it means either the air pressure has not changed or the change

has been too slow for the Weather station to register. However, if the icon

displayed is a sun or raining cloud, there will be no change of icon if the

weather gets any better (with sunny icon) or worse (with rainy icon) since the

icons are already at their extremes.
