4.3 CLOCK WINDOW

For all operations described in Chapter 4.5, press

 UP (

or 

DOWN (

)

 until the

TIME

 icon, in the left corner of the time window, begins to flash.

4.3.1 TIME FUNCTION

The radio controlled time signal (DCF 77) is transmitted from the central atomic clock in 

Frankfurt/Main. It has a reception range of approx. 1500 km. If the tower icon is not fully 

lit, or if the time and date are not set automatically, please consider the following: 

During night-time hours, atmospheric disturbances are typically less severe and radio 

signal reception may improve. A single daily reception is sufficient enough to keep the 

clock accuracy within 1 second.

Make sure the unit is positioned at least 2 meters (8 feet) distance from any interference 

source such as a TV, computer monitor, microwave, etc.

Within concrete and /or metal wall rooms, such as basements or office buildings, the 

signal may be weakened. In such a case, place the main unit near the window for better 

reception. Sometimes it also helps to turn the unit by 90°

NOTE: In any of below described settings, the unit will automatically exit any 

programming mode if it does not detect a button press for about 2 minutes. Any setting 

made before this will not be taken over by the unit. Therefore, as long you are in a setting 

and you have made changes, close the setting mode as described in below chapters.

HOW TO SET THE RADIO CONTROLLED CLOCK

1. After the batteries are installed. The clock will search the radio signal automatically 

    (DCF77 from Germany). It takes about 3-10 minutes to finish this process.

2. If you wish to disable the auto-reception feature, hold 

UP (

)

 for 3 seconds to disable 

    it. Having done that, the tower icon will disappear.

3. To enable the auto-reception feature again, hold 

UP (

)

 for 3 seconds again to start the 

    reception and the regular synchronization (daily at 0:00, 3:00, 6:00 and 12:00).

6.  BATTERY CHANGE

   

      : BATTERY CHANGE DISPLAY

The batteries last for around 8-12 months. Depending on the usage of the unit and the 

batteries used, this time can be slightly shorter or longer. In order to avoid a surprising 

and unpleasant interruption to operations, a battery symbol may appear

- in the

 temperature window

 with the corresponding channel. 

This means that batteries of the displayed sensor are becoming weak and need to be 

replaced.

- in the 

time window

This means that batteries of the main unit are becoming weak and need to be replaced.

To change the batteries, please also consult Chapter 3 (Putting into operation).

Important: 

- Insert batteries in the correct polarity

- Use only new batteries and never mix old and new batteries.

Please also remember that used batteries should not be thrown in the household rubbish 

bin but handed in at the designated collection points. The environment will thank you for 

it!
