Radio outdoor sensor

Securely placing or mounting the weather station

The weather station with radio outdoor sensor is not designed for operation in rooms with high humidity (i. e. bathroom). not designed for use in rooms with high humidity (e.g. bathrooms). Use the supplied dowel and screw for wall mounting. Before mounting to a wall, make sure that there are no gas, water or electricity lines at the drilling location. Pay attention to the condition of the wall. The enclosed mounting material is not suitable for all types of walls. The manufacturer is not liable for any damage caused by improper mounting.
Protect sensitive surfaces before setup, otherwise scratches may occur. Make sure that:

• sufficient ventilation is always guaranteed (don’t place the device on shelves or where curtains or furniture block the ventilation slots 22 , and ensure that there are at least 10 cm of space on all sides);
• the device isn’t placed on a thick carpet or bed during operation, no direct heat sources (i.e. radiators) influence the device;
• no direct sunlight reaches the device;
• contact with splashing or dripping water must be avoided (don’t place any items filled with liquids, i.e. vases, onto or next to the device);
• the device doesn’t stand near magnetic fields (i.e. speakers);
• no foreign objects or dust penetrate the housing;
• candles and other open flames must be kept away from this product at all times to prevent the spread of fire.

Securely placing or mounting the radio outdoor sensor

Place the sensor in a location where it is protected from the weather, for example under an awning or carport. The sensor has an IPX4 rating and is therefore protected from water splashes. not designed for use in rooms with high humidity (e.g. bathrooms). Use the supplied dowel and screw for wall mounting. Before mounting to a wall, make sure that there are no gas, water or electricity lines at the drilling location. Pay attention to the condition of the wall. The enclosed mounting material is not suitable for all types of walls. The manufacturer is not liable for any damage caused by improper mounting.
Protect sensitive surfaces before setup, otherwise scratches may occur. Make sure that:

• the sensor hangs or stands upright;
• sufficient ventilation is always guaranteed (don’t place the device on shelves or where curtains or furniture block the ventilation holes, and ensure that there are at least 10 cm of space on all sides);
• no direct sunlight reaches the device;
• the device doesn’t stand near magnetic fields (i.e. speakers);
• no foreign objects or dust penetrate the housing;
• sensitive surfaces are protected before placement.

Setup

** Insert the batteries into the battery compartment of the radio outdoor sensor 36 and only then insert batteries into the battery compartment of the radio-controlled weather station 23**.

Remove the protective film from the display. Open the battery compartment of the radio outdoor sensor 36 and insert the included batteries in the correct polarity.
The operation LED 31 lights up briefly and the temperature is displayed.
Close the battery compartment. Open the battery compartment of the radio- controlled weather station 23 and insert the included batteries in the correct polarity.
Close the battery compartment.
The display will turn on For 5 seconds and a tone will sound. The radio- controlled weather station will measure the indoor temperature and indoor humidity. Then the radio-controlled weather station will begin to receive the temperature and humidity from the radio outdoor sensor.
The radio waves 12 will blink. The process can take up to 3 minutes. If radio signal reception is not possible, the radio-controlled weather station will abort the process. The radio-controlled weather station now starts reception of the DCF77 radio control signal. The radio control symbol 10 will blink on the display. This process can take from 3 to 10 minutes. During the reception process, all buttons except the SNOOZE/LIGHT button 7 will not function. If the reception of the radio time signal remains unsuccessful after 10 minutes, the radio control symbol 10  will disappear from the display. Set the time manually (see basic settings). The radio- controlled weather station will start a new reception attempt at 04:00 o’clock and 05:00 o’clock and the time will be corrected automatically if reception is successful.

Note: Please do not move the radio-controlled weather station during the reception process.

If reception is successful, the radio control symbol 10 will appear on the display permanently and the correct time will be set automatically. During daylight saving time, DST will appear on the display to the left of the radio control symbol 10 .

Time zone adjustment

If you are in a country, in which the clock displays the wrong time even though it can receive the DCF77 time signal, please use the time zone adjustment to use your weather station in a time zone other than the standard time zone (UTC+1 = Central European Time). Set the difference in hours (- 01 for example) to the desired time zone.
Press and hold 1 x long and 2x briefly the °C/°F-SET-button 18 in normal time display mode. The time zone will blink and can be set with the MEM- -button 17 or the CH- -button 16. Press the °C/°F-SET- button 18 to confirm your setting. The 12/24 hour time format will blink. Press the button again and the radio-controlled weather station will return to the normal setting. The radio-controlled weather station will show the changed time (for example: 1 hour less).

Reception problems

The DCF77 radio signal is transmitted from a location near Frankfurt am Main and can be received within a radius of approximately 2000 km around Frankfurt am Main. However, there are some obstacles and sources of interference, which may substantially hinder reception. If your weather station does not correctly receive the DCF77 radio signal, please hang or place the weather station in a different location at your site. Please note that devices such as computers, telephones, radios and televisions may cause electromagnetic radiation which can interfere with the DCF77 signal reception. Other possible detriments to reception are: strong building insulation (metal building materials), nearby mountains or atmospheric interference. It may also be necessary to replace the batteries.

**Turning radio control signal reception on or off

Radio control reception can be turned off temporarily by pressing and holding the MEM- -button 17 2 x for 3 seconds. The radio control symbol 10 will disappear from the display. The radio-controlled weather station will no longer receive the radio control signal but will restart reception every hour between 01:00 and 05:00 o’clock. Alternatively press and hold the MEM- -button 17 to restart DCF77 radio control signal reception.
To permanently turn off radio control signal reception, press and hold both the MEM- -button 17 and the CH- -button 16 together for 3 seconds. The radio control symbol 10 will disappear. The radio-controlled weather station will now no longer receive the DCF77 radio control signal.
Press and hold the MEM- -button 17 and the CH- -button 16 together for 3 seconds and the radio wave symbol 10** will disappear. The radio-controlled weather station can now receive the DCF77 signal again.

The radio-controlled weather station will attempt to receive the radio control signal hourly between 01:00 and 05:00 o’clock and correct the time automatically if reception is successful. If reception is successful, the radio control symbol 10 will appear on the display permanently.

Restarting radio control signal reception

Radio control signal reception can be restarted by pressing and holding the MEM-  -button 17 for 3 seconds. The radio control symbol 10 will blink on the display. The radio-controlled weather station will now start the DCF77 signal reception attempt. This process can take from 3-10 minutes.
