THE OUTDOOR TEMPERATURE TRANSMITTER

SETTING UP:

Note: This temperature 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 Temperature
station (see “Install and replace batteries in the Temperature station”).
Once the batteries are in place, all segments of the LCD will light up briefly.
Following the time as 0:00 will be displayed and indoor temperature. If these
are not displayed after 60 seconds, remove the batteries and wait for at least
10 seconds before reinserting them.

3. After inserting the batteries, the Temperature station will start receiving data
from the transmitter. The outdoor temperature and the signal reception icon
should then be displayed on the Temperature station. If this does not happen

• Remote transmission of outdoor temperature to
temperature station by 868MHz

• Weather-resistant casing

• Wall mounting case

• Mount in a sheltered place. Avoid direct rain and

sunshine

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 Temperature station and the transmitter (see notes on
“Mounting” and “868 MHz Reception”).

5. Once the remote temperature has been received and displayed on the
Temperature station, the DCF time (radio controlled time) code reception is
automatically started. This takes typically between 3-5 minutes in good
conditions. If after 10 minutes, the DCF time has not been received, press the
SET key to manually enter a time initially.

Note:

Daily DCF reception is done at two hours interval until a reception is successful for
the day. If the reception is still not successful, then the next try takes place at 00:00
the next day.

If reception is successful, the received time will override the manually set time. The
date is also updated with the received time. (Please refer also to notes on “DCF-77

Radio Controlled Time” and “Manual Time Setting”)

TRANSMITTER

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
Temperature station in the first 3 minutes of power being supplied to it.

BATTERY CHANGE:

It is recommended to replace the batteries in all units regularly to ensure optimum
accuracy of these units (Battery life see Specifications below).

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.

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