Initial operation:
 Open Weather Station battery compartment cover
 Insert 2 x AA batteries observing polarity [ “+” and “ –“ marks]
 When you insert the batteries, all the icon on the LCD display will briefly light up for 3 seconds, and you will
hear a beep tone, and detect indoor temperature & humidity.
 Then insert 2 x AAA batteries in the outdoor sensor observing polarity [ “+” and “ –“ marks]. Be sure the
switch button is on channel 1.
 The Weather Station will now start to make a connection to the OUT sensor. This operation takes about 3
minutes and is displayed by a flashing reception RF antenna symbol in the “OUT” display area on the
receiver.
 After receiver has created a connection to the OUT sensor, it will then be enters the Radio control time
receive mode.
Reception of the Radio signal:
 The clock automatically starts the DCF signal search after 3 minutes of any restart or changing of new fresh
batteries. The radio mast icon starts to flash.
 At 1:00 /2:00 / 3:00 am, the clock automatically carries out the synchronization procedure with the DCF
signal to correct any deviations to the exact time. If this synchronization attempt is unsuccessful (the radio
mast icon disappears from the display), the system will automatically attempt another synchronization at the
next full one hour. This procedure is repeated automatically up to total 5 times.
 To start manual DCF signal reception, press and hold down the “+” button for two seconds. If no signals
