WIRELESS WEATHER STATION
C-8123/C-8153
USER’S INSTRUCTIONS
P17812300030
The multifunctional weather station is equipped with many
functions providing thorough weather information to you.
The receiver unit has a clear, easy-to-read display that
shows weather forecast, indoor temperature, relative
humidity, pressure, moon phase, time and date, as well as
the temperature and relative humidity measured and
transmitted by the sensor. It is able to receive and display
readings from up to 3 remote sensors.
The receiver unit retains the minimum and maximum
temperatures and relative humidity readings measured at
various locations. The 433 MHz technology means no wire
installation is required and you can place the sensors
anywhere you like.
With radio controlled function, the current time and date
are automatically synchronized with the time signal
transmitted from Frankfurt Germany (DCF77) / UK (MSF) /
US (WWVB). The signal can cover a distance of about 1500
km from the related transmitter.
Note:
C-8153 is without humidity.
FCC Remarks:
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) This device must accept any
interference received, including interference that may cause
undesired operation.
Warning: Changes or modifications to this unit not expressly
approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:
l Reorient or relocate the receiving antenna.
l Increase the separation between the equipment and receiver.
l Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
l Consult the dealer or an experienced radio/TV technician for
help.
