Note
-
Place the sensor out of direct sunlight and
moisture.
-
Do not place the sensor more than 30 m (100 ft)
from the main (indoor) unit.
-
Position the sensor so that it faces the main
(indoor) unit, minimizing obstructions such as
doors, walls, and furniture.
-
Place the sensor in a location with a clear view
to the sky, away from metallic or electronic
objects.
-
Position the sensor close to the main unit
during cold winter months as below-freezing
temperatures may affect battery performance
and signal transmission.
The transmission range may vary depending on
many factors. You may need to experiment with
various locations to get the best results.
Standard Alkaline batteries contain significant
amounts of water. Because of this they will freeze
in low temperatures of approximately -12°C (10°F).
Disposable Lithium batteries have a much lower
threshold for temperature with an estimated freezing
range of below -30°C (-22°F).
Wireless ranges can be impacted by a variety of
factors such as extremely cold temperatures.
Extreme cold may temporarily reduce the effective
range between the sensor and the base station. If
the unit’s performance fails due to low temperature,
the unit will resume proper functioning as the
temperature rises to within the normal temperature
range (i.e. no permanent damage will occur to the
unit due to low temperatures).
RECEPTION OF RADIO CONTROLLED TIME SIGNAL
The time and calendar are radio-controlled. The
current time and calendar are automatically
synchronized with time signal transmitted from
Germany/England.
When used for the first time (after inserting batteries
or pressing “RESET” key), the clock will start to
receive the time signals and the signal reception
indicator will be flashing for 5 minutes.
SIGNAL RECEPTION INDICATOR
The wave segment flashing means time signals are
being received. The signal quality could be classified
into 3 types:
No signal
Weak signal
Excellent signal
