Radio Controlled Time - La Crosse Technology WT-8112-U Instruction Manual

SETUP AFTER CHANGING/REPLACING THE
BATTERY
1. After powering up the solar clock, all LCD segments will
light up briefly and it will show the time (00:00), indoor
temperature, date, and indoor humidity.
2. Next, the DCF time code reception will automatically
start. This takes typically between 3 - 5 minutes in good
conditions. If after 10 minutes the DCF time has not been
received, use the "SET" key to enter the set-up mode to
manually set the Time, Time Zone and Date (see manual
settings below). The clock will continue to search for DCF
at 3am and 5am. When the clock has successfully
connected with DCF signal, it will override the manually
set time and date.
Note: When changing the battery:
1. Be careful that it does not spring free from the
contacts.
2. Always wait at least 1 minute after removing
battery before re-inserting, otherwise start up
problems may occur.

RADIO CONTROLLED TIME

The time base for the radio controlled time is a Cesium clock
operated by the Physikalisch Technische Bundesanstalt
Braunschweig, which 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 Weather Station receives this signal
and converts it to show the precise time in summer or
wintertime.
The quality of the reception depends greatly on the geographic
location. In normal cases, there should be no reception
problems within a 1500km radius of Frankfurt.
Once the indoor temperature is displayed on the solar wall
clock, the DCF tower icon in the clock display will start flashing
in the LCD. This indicates that the clock has detected that there
is a radio signal present and is trying to receive it. When the
