Frequently Asked Questions - Modus Plus TFA

How to install the Modus Plus weather station?

Place the base station indoors and the outdoor sensor outdoors (sheltered from rain). Insert batteries into each unit. The radio link establishes automatically.

What to do if the outdoor display shows '--'?

Check that the sensor batteries are correctly installed and the distance does not exceed 100 m. Reset both devices by removing the batteries for 10 seconds.

How to set the time and date?

Press and hold the SET button until the time blinks. Use the + and - buttons to adjust, then press SET to move to the next parameter.

How to interpret the weather forecasts?

The icons (sun, cloud, rain) indicate the trend for the next hours. Accuracy is based on atmospheric pressure.

What type of batteries to use?

Use good quality alkaline batteries: AAA for the base station, AA for the outdoor sensor. Avoid rechargeable batteries (insufficient voltage).

How to reset the station?

Remove all batteries from both units, wait 10 seconds, then reinsert them. The station will restart in search mode.

Why is the outdoor temperature not updating?

Ensure the sensor is within 100 meters and not obstructed by thick walls. Change the batteries if they are low.

How to turn on the backlight?

Briefly press the LIGHT/DOWN button to activate the backlight for a few seconds. Some models turn on automatically in low light.

Can the station be mounted on the wall?

Yes, the base station has a wall mount on the back. Use a suitable screw. The outdoor sensor can be fixed using a provided bracket.

What to do in case of pressure error?

Calibrate the pressure according to your altitude. Consult the manual for the manual relative pressure adjustment procedure.

6. Getting started

Insert batteries:

• Place both instruments on a desk with a distance of approximately 1.5 meter. Check that no other electronic devices are close.
• Insert at first three new batteries 1,5 V AA in the battery compartment of the base station and then two new batteries 1,5 V AA in the battery compartment of the outdoor transmitter. Make sure the polarities are correct.

Reception of outdoor temperature and humidity

• The base station automatically starts scanning the signals to register the outdoor transmitter after batteries are inserted. The basic unit will scan for 2 minutes the outdoor values. The reception symbol flashes.
• The LED indicator of the transmitter is flashing. The outdoor transmitter is set to channel 1 by default.
• If the reception of outdoor values fails, “- -” appears on the display. Check the batteries and try it again. Check if there is any source of interference.
• Manual initialization can be helpful. Press and hold ▲/CH button for 3 seconds. The reception symbol flashes. The weather station will only search for an outdoor transmitter on the actual selected channel.

Radio-controlled time reception

• The clock will now scan the DCF frequency signal and the DCF symbol flashes on the LCD. When the time code is received successfully after 3-8 minutes, the radio-controlled time is displayed and the DCF symbol remains permanently on the display. During the DCF time reception period, no outdoor values will be transmitted.
  • There are 3 different reception symbols:

- reception is active

- reception is very good

- No DCF reception

• To activate the DCF reception, press the ALARM button for 2 seconds. The reception signal - symbol flashes. Press the ALARM button again to stop scanning DCF time signal.
• If the clock cannot detect the DCF-signal (for example due to disturbances, transmitting distance, etc.), the clock can be set manually.
• The clock will then work as a normal quartz clock. (see: Manual setting of the clock, calendar and day-of-week language).

Note for radio-controlled time DCF:

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 frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. Your radio controlled clock receives this signal, converts it to shows the precise time. Changeover from summer time or winter time are automatic. The quality of the reception depends mainly on the geographic location. Normally there should be no reception problems within a 1,500 km radius around Frankfurt.

Please take note of the following:

• The recommended distance to any interfering sources like computer monitors or TV sets is at least 1.5 - 2 metres.
• Inside ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window to improve the reception.
• During nighttime, 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.

7.13 Positioning and fixing of base station and outdoor transmitter

• With the foldable leg at the back of the unit, the base station can be placed onto any flat surface or wall mounted at the respective location by the hanging hole at the back of the unit. Avoid the vicinity of any interfering field like computer monitors or TV sets and solid metal objects.
• Choose a shady and dry position for the transmitter. (Direct sunshine falsifies the measurement and continuous humidity strains the electronic components needlessly).
• Check the transmission of the signal from the outdoor transmitter to the base station (transmission range 75 m free field). Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened.
• If necessary choose another position for the outdoor transmitter and/or base station.
• If the transmission is successfully, fix the outdoor transmitter by using a nail (not included) on the wall or place it onto a flat surface.

8. Care and maintenance

• Clean the instruments with a soft damp cloth. Do not use solvents or scouring agents.
• Remove the batteries if you do not use the products for a long period of time.
• Keep the instruments in a dry place.

8.1 Battery replacement

• Replace the batteries when the battery symbol of the base station appears next to the time display.
• When the batteries of the transmitter are used up, the low battery icon appears next to the outdoor temperature display.
• Make sure the polarities are correct. Close the covers again.
• Please note: When the batteries are changed, the contact between transmitter and receiver must be restored – so always insert new batteries into both units or start a manual transmitter search.
