Batteries must not be thrown into a fire, short-circuited, taken apart or recharged. Risk of explosion!
Low batteries should be changed as soon as possible to prevent damage caused by leaking. Make sure the polarities are correct. Never use a combination of old and new batteries together, nor batteries of different types.
Remove the batteries if the device will not be used for an extended period of time.

- 5.1 Insert the batteries
Place the instruments on a table at a distance of about 1.5 meters from each other. Avoid being close to possible sources of interference such as electronic devices and radio equipment.
Open the battery compartment of the transmitter and insert two new AA 1.5 V batteries, polarity as illustrated. All LCD segments will be displayed for a short moment. The display shows the temperature. The switch is set to channel 1.
Close the battery compartment.
Remove the protective film from the base station dis play.
Open the battery compartment of the base station.
Insert two new AA 1.5 V batteries, polarity as illustrated. All LCD segments will be displayed for a short moment. The indoor temperature appears on the dis-play.
Close the battery compartment.

Reception of outdoor transmitter

The base station will scan the outdoor temperature and the reception symbol flashes.
If the reception is successful, the outdoor temperature and the reception symbol appear steadily on the base station display.

Wireless Thermometer

If the reception of the outdoor temperature fails, “- -,-” remains on the display. Check the batteries and try it again.
You can also activate the reception manually. Press and hold the +/CHANNEL button on the base station for three seconds. The reception symbol for the out-door transmitter will be flashing.
Press the TX button in the transmitter’s battery compartment. The transmission of the outdoor data takes place immediately and if the reception is successful, the outdoor temperature appears on the base station display.

Reception of the DCF frequency signal

After the reception of the outdoor values, the clock will now scan the DCF frequency signal and the DCF symbol flashes on the display.
When the time code is successfully after 3-10 minutes, the radio-controlled time, the date and the DCF symbol will be shown steadily on the display.
The DCF reception always takes place at 1:00, 2:00 and 3:00 o’clock in the morning. If the signal is not successfully received, further attempts will be taken at 4:00 and 5:00 o’clock.
If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can be set manually.
The clock will then work as a normal quartz clock (see: “Manual settings”).

Note on radio-controlled time

The time is transmitted from an atomic clock near Frankfurt am Main by a DCF-77 (77.5 kHz) frequency signal with a range of about 1,500 km. Your radio-con-trolled clock receives the signal, converts it and always shows the exact time. The adjustment of Daylight Saving Time and Standard Time is also automatic.
During night-time, the atmospheric interference is usually less severe. A single daily reception is adequate to keep the accuracy deviation under 1 second. In extreme cases, please place the unit close to a window to improve reception.

Operation

Manual settings

Press and hold the SET/MAX/MIN button for three seconds to enter the setting mode.
The first adjustable value flashes on the display.
Use the +/CHANNEL button to make the desired setting.
Confirm with the SET/MAX/MIN button and go to the next setting.
The sequence is shown as follows:
- DCF reception ON/OFF (default: DCF ON)
- Time zone -12/+12 (default: DCF 00H)
- Hours, minutes
- Year, month, day
- Automatic reset of the maximum and minimum values ON/OFF (default: AUTO OFF MAX MIN)
Press and hold the +/CHANNEL button in the respective setting mode for quick setting. The device will automatically quit the setting mode if no button is pressed for 20 seconds.

DCF reception

By default, the DCF reception is activated (DCF ON) and after successful reception of the DCF signal no manual time setting is necessary.
Once the DCF time reception is deactivated (DCF OFF), the clock and date must be manually set. No time zone will appear.
If the DCF reception is activated, the manually set time will be overwritten by the DCF time when the signal is received successfully.

Time zone setting

In the setting mode you can make the time zone correction.
The time zone correction is needed for countries where the DCF signal can be received but the time zone is different from the DCF time (e.g. +1=one hour plus).

Automatic reset of the maximum and minim values

In the setting mode you can activate (AUTO ON) or deactivate (AUTO OFF) the automatic reset of the maximum and minimum values.

Wireless Thermometer

If the automatic reset is activated, AUTO appears on the display besides the current time display.
All maximum and minimum values will be reset auto manically very midnight at 0:00.

Maximum/Minimum function

Indication of maximum and minimum values

Press several times the SET/MAX/MIN button in nor- mal mode.
You can now see the highest (MAX) and lowest values (MIN) since the last reset with time and date of recording.
The sequence is shown as follows: indoor tempera- ture (MAX), indoor temperature (MIN), outdoor temperature (MAX), outdoor temperature (MIN).
Press the SETMAXIMIN button again to return to nor mal mode.
The device will automatically quit the MAX/MIN mode if no button is pressed.

Reset of maximum and minimum values

Manual reset
- Press and hold the SET/MAX/MIN button while the highest or lowest values are displayed. The values will be deleted individually and reset to the current state.
Automatic reset
- Provided that in the setting mode the automatic reset is activated (AUTO ON). The AUTO symbol appears on the display.
- All maximum and minimum values will be reset auto magically every midnight at 0:00.
- An interim manual reset is still possible.

Installation

When placed outdoors, choose a shady and dry place for the transmitter. Direct sunlight may trigger incorrect measurement and continuous humidity damages the electronic components needlessly.
Before the final installation, make sure that the measured values are transmitted from the transmitter at the desired installation site to the base station.
Do not use the base station in the vicinity of radiators, other sources of heat or in direct sunlight.

Wireless Thermometer

Make sure to avoid the vicinity of any source of interference such as computer screens, TV sets or solid metal objects. Within solid walls, especially ones with metal parts, the transmission range (max. 100 m) can be reduced considerably.

Battery replacement

As soon as the corresponding battery symbol appears in the display, please change the batteries of the base station or transmitter
Please note: When the batteries are changed, the con-tact between the outdoor transmitter and the base sta-tion must be restored – so always restart both devices or start a manual transmitter search.

Additional outdoor transmitters (optional)

When having more than one external transmitter, select a different channel for each one with the 1/2/3 switch inside the transmitter’s battery compartment. Insert two new AA 1.5 V batteries, polarity as illustrated. Start the base station operation or the manual search for the outdoor transmitter:
Choose the respective transmitter by pressing the +/CHANNEL button.
Press and hold the +/CHANNEL button for three seconds. The last registered transmitter (channel) will be cancelled.
Press the TX button in the corresponding transmitter’s battery compartment. The transmission of the out-door data will take place immediately.
The outdoor temperature and the channel number will be shown on the base station display. If you have installed more than one outdoor transmitter, press the+/CHANNEL button on the base station to change
between the channels 1 to 3.
You can also choose an alternating channel display. Press the +/CHANNEL button. After the last registered channel (1 to 3) a circle symbol will appear. To deactivate the function, press the +/CHANNEL button again.
Press the SET/MAX/MIN button several times to view the maximum and minimum values of the currently selected channel.
• After a successful installation close the outdoor transmitter’s battery compartment carefully.
