If the temperature is not between 20°C and 28°C, or the relative humidity is between 40 and 70%, there is no display of information.

Outdoor temperature and humidity

Pressing the CHANNEL button will select temperature or relative humidity display from among transmitters 1, 2 or 3.

On the outdoor transmitters

The temperature, relative humidity (RH) and current channel will display on the LCD display of the outdoor transmitter. The °C/°F button
under the battery compartment lid is used to switch between °C and °F temperature display. This setting has no effect on the outdoor
temperature unit displayed on the weather station.

pair the outdoor transmitter.
Then the setting will continue with the automatic reception of the DCF77 clock signal. The DCF77 signal (9) will flash on the display.

TROUBLESHOOTING

Meanwhile, position the weather station so that it receives a clear DCF77 signal. This is indicated by the full DCF77 symbol flashing. A
stronger signal can be received in a westward facing window, far from TV sets or monitors, and at night when interference is at a
minimum.
Setup takes 3-8 minutes and on successful setup, the DCF77 symbol will display. This completes setup of the time and date.
If no signal can be received, try manually tuning in the DCF77 clock signal, or setting the time, date and day of week language manually.
The day of week language can only be set manually.

Location

The weather station and the outdoor transmitter can be either wall-mounted or placed on a horizontal surface by opening the stand. To
ensure accurate measurement, select a dry and shaded location for the outdoor transmitter. Even though it is resistant to splashing
water, it must not be exposed to constantly high humidity.
Preferably move the units away from other electromagnetic signal sources that may cause electrical interference.
Please note that the transmitter's range is 60 m in the open range, which of course is reduced by building walls, reinforced concrete
structures and other radio-frequency interference sources.

Manual Pairing of Outdoor Transmitter

The default channel used by the outdoor transmitter is Channel #1. If you want to use additional outdoor transmitters (max. 3) with the
weather station, they must be set to unique channels.
Setting channels other than Channel #1: after inserting the battery, select channel #1, #2 or #3 by pressing the CH button on the outdoor
transmitter. The outdoor transmitter's LCD display will accordingly show CH 1, CH 2 or CH 3. Afterwards, keep the CHANNEL button
pressed on the weather station until a short beep is heard. Then the weather station will search and register any new outdoor

transmitters again while the signal icon will continuously blink. On successful reception, the outdoor temperature and humidity will
display alongside the channel number.

Care

If no signal is received, check the batteries in both the weather station and the outdoor transmitter.

A slightly dampened cloth can be used to clean the equipment. Aggressive detergents can mar the units' finish.

Do not allow water to enter the weather station.

Manual reception of DCF77 clock signal

When not planning to use the units for an extended period of time, remove the batteries.

DCF77 is a long-wave (77.5 kHz) atomic clock synchronization signal transmitter in Mainflingen, Germany, 25 km SE from central
Frankfurt. The atomic clock is accurate to 1 second per one million years. The signal can be received inside a radius of 2000 km, thus

Important!

The outdoor transmitters must be paired with the weather station after battery replacement.

If synchronization fails even on completing the set-up procedure, manual adjustment of the time and date is possible.
