‚ At low temperatures in winter, the performance of the
outdoor sensor batteries can markedly decrease. This
reduces the transmission range.
‚ Depending on your location, it can infrequently
happen that the base station receives signals from
another time signal transmitter or even alternately
from two time signal transmitters. This is not a fault in
the device. In this case you should change the location
of the base station.
As regards the signal reception between the time signal
transmitter and the base station, pay attention to the
following points:
‚ Maintain distance from TV sets, computers, and
monitors. Also, base stations from cordless phones
should not be located in immediate proximity to the
weather station.
‚ The reception is generally better at night. If the alarm
did not receive a signal during the day, it may well be
that the signal is received at night, immediately and at
full strength.
‚ The weather, e.g. a heavy storm, can cause
interference with the reception.
‚ Temporary shutoffs of the transmitter can sometimes
happen, e.g. because of maintenance work.
