Getting started
Insert the batteries
- Place the instruments on a desk with a distance of approximately 1.5 meters. Avoid being close to pos-sible sources of interference such as electronic devices and radio installations.
- Open the battery compartment of the transmitter.
- Set the switch to the channel 1 position.
- Insert two new AA 1,5 V batteries, polarity as illustrated.
- Close the battery compartment carefully.
- Open the battery compartment of the base station and insert two new AA 1.5V batteries, polarity as illustrated.
- All segments will be displayed briefly.
- Close the battery compartment again.
Transmitter reception
- After the batteries are inserted the base station will automatically receive the measured values. The reception symbol will be flashing on the display.
- If the reception of the measured values fails, “- -“”appears on the display. Check the batteries and try it again. Check if there is any source of interference.
- As soon as the base station receives the radio-controlled time, you can start the transmitter’s manu-al initialization. Press and hold the CHANNEL button for four seconds. The base station tries to receive the measured values.
- Press the TX button to transmit the measured values manually.
Radio-controlled time reception
-
After the base station has completed searching for the transmitter, the device starts scanning the DCF signal and the DCF reception symbol will be flashing.
-
When the time code is successfully received after 2-10 minutes, the radio-controlled time, the date, the DST (if applicable) and the DCF symbols will be shown steadily on the display.
-
The DCF reception always takes place hourly between 1:00 and 5:00 o’clock in the morning. If the reception is not successfully received until 5:00 o’clock, the next DCF reception attempt will happen at 1:00 o’clock in the following morning.
-
There are three different reception symbols:
flashing – reception is active
solid – reception is very good
no symbol – no reception / set the clock manually -
If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can be set manually. The DCF reception symbol disappears and the clock will then work as a normal quartz clock (see: Manual settings).
Note on radio-controlled time
The time base for the radio-controlled time is a caesium atomic clock operated
by the Physikalisch Technische Bundesanstalt Braunschweig. It has a time
deviation of less than one second in one million years. The time is coded and
transmitted from Mainflingen near Frankfurt via the frequency signal DCF-77
(77.5 kHz) and has a transmitting range of approximately 1,500 km. The
adjustment to Daylight Saving Time (summer/winter time) is automatic. In
Daylight Saving Time the DST symbol is shown on the display. The reception
quality depends mainly on geographic location. Normally there should be no
reception problems within a 1,500 km radius around Frankfurt.
Therefore, please note the following steps
- The recommended distance to any interfering sources like computer screens or TV sets is at least 1.5 – 2 meters.
- Within concrete walls (reinforced with steel) such as basements, the received signal is naturally weakened. In extreme cases, please place the unit close to a window to improve reception.
- During night-time, the atmospheric interference is usually less severe and reception is possible in most cases. A single daily reception is adequate to keep the accuracy deviation under 1 second.
Operation
- Important: a button operation is not possible during the reception of the transmitter or of the radio-controlled time signal.
- Press and hold the MAXMIN/+ or RCC/- button in the respective setting mode for fast setting.
- The device will automatically quit the setting mode if no button is pressed for 20 seconds.
Manual settings
- Press and hold the SET button in normal mode.
- RCC appears on the display and on (default) will be flashing.
- Press the MAXMIN/+ or RCC/- button to deactivate (OFF) or activate (on) the DCF time reception.
- Once the DCF time reception is deactivated, the clock must be manually set.
- Press the SET button to do the settings in the following sequence: Time zone (0 – default), the 12 or 24- hour system (24hr – default), the hours, the minutes, the year, the month, the day, the language of the day of the week (GERMAN – default), and the temperature display (°C – default). Press the MAXMIN/+ or RCC/- button to adjust it.
- Confirm with the SET button.
- Once the DCF time signal is successfully received, the manually set time is overwritten, if the DCF reception is activated.
Time zone setting
- In the setting mode you can make the time zone correction (-12/+12).
- 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).
12/24-hour display setting
- Press the MAXMIN/+ or RCC/- button in the setting mode to choose between the 12 or 24-hour system.
- In the 12-hour system AM or PM (after 12 o’clock) appears on the display as well as the American date format (month first, then the day).
Day-of-the week language
Press the MAXMIN/+ or RCC/- button in the setting mode to select between
the day-of-the week language: GERMAN, ENGLISH, FRENCH, SPANISH, ITALIAN and
DUTCH.
Temperature display setting
Press the MAXMIN/+ or RCC/- button in the setting mode to select the
temperature display in °C (Celsius) or °F (Fahrenheit) as temperature unit.
Trend arrows
The trend arrows indicate whether the temperature and humidity values are
currently increasing or decreasing. If the arrows are steady, there is no
change.
Maximum/Minimum function
- Press the MAXMIN/+ button in normal mode.
- appears on the display.
- The maximum values measured since the last reset appear on the display.
- Press the MAXMIN/+ button again.
- appears on the display.
- The minimum values measured since the last reset appear on the display.
- When the maximum or the minimum values are displayed, press and hold the MAXMIN/+ button for four seconds to reset the corresponding values.
- Press the MAXMIN/+ button again to return to normal mode.
Positioning and mounting of the base station and the transmitter
- Place the base station at the final position. Avoid the vicinity of any source of interference such as computer screens, TV sets or solid metal objects.
- The transmitter can be wall mounted (mounting hole at the back). When placed outdoors, choose a shady and dry place for the transmitter. Direct sunlight may trigger incorrect measurement and continuous humidity strains the electronic components needlessly.
- Once the desired location is chosen, check if the transmission from transmitter to the base station is possible (transmission range of up to 80m in open areas), within solid walls, especially with metal parts, the transmission range can be considerably reduced.
- If necessary choose another position for the transmitter and/or base station.
Care and maintenance
- Clean the devices with a soft damp cloth. Do not use solvents or scouring agents.
- Remove the batteries if you do not use the devices for a long period of time.
- Keep the devices in a dry place.
Battery replacement
- When the battery symbol appears on a channel display, change the batteries of the respective transmitter.
- Change the batteries of the base station, when the battery symbol appears on the display of the indoor values.
- Please note: When the batteries are changed, the contact between transmitter and base station must be restored – so always start a manual transmitter search or make a restart according to the manual.
