played (CH1 to CH3) (if only one remote sensor is connected, always se-

4. Reinsert the battery compartment door.
Low battery warning
When batteries need to be replaced the respective low battery indicator
will be shown near the indoor temperature display (batteries for main unit)
or near to the outdoor temperature (batteries for remote sensor).
USING TABLE STAND OR WALL MOUNTING
The main unit has a removable table stand, which - when connected - can
support the unit on a flat surface. It is possible to remove the stand and
mount the unit on a wall using the recessed screw hole. The same applies
to the remote unit; it can be placed on a flat surface or mounted on a wall
using the recessed screw hole.
OPERATION
Receiving measurements and time signal
Once batteries are placed in the remote unit, it will start transmitting tem-
perature readings at roughly 45 second intervals. As soon as batteries are
installed in the main unit it will start searching for a signal from the remote
sensor for about 3 minutes. Upon successful reception of the signal, the
outdoor temperature will be displayed on the main unit. The main unit will
automatically update its readings at about 45 second intervals.
Subsequently, the main unit will attempt to receive the DCF77 radio signal.
The reception symbol flashes. When the time signal is received after 3-5 min-
utes, the current time and date appear in the display. The reception symbol
will now be shown permanently in the display. Date and time are automati-
cally updated daily at 2:05 o’clock (CET) by the main unit.
Temperature and humidity
Once the batteries are installed the main unit will start displaying the inte-
rior measurement information. The main unit will display the information
from the remote sensor for the first time approximately 3 minutes after the
power supply was established.
COMFORT LEVEL
humidity is same or lower than 40%

Max/Min records of temperature and humidity
1. Pressing and releasing the UP button in short intervals repeatedly makes
the display alternate between the current temperature and humidity as
well as MIN/MAX recordings.
