Operation - Bresser National Geographic Operating Instructions Manual

• The international standard for accurate air temperature measurements is 1.25 metres (4 feet) above
the ground.
• Make sure that the base station is located within the operating range of all outdoor sensors.
• Ideally, the base station should be placed within line of sight of the outdoor sensors. Avoid placing
the base station near surfaces that emit or radiate heat (e.g. heating ducts or air conditioners) and
areas with interference from wireless devices (e.g. cordless phones, radio headsets, baby monitor-
ing devices and other electronics).
Important notice about batteries
• The weather station comes with batteries to make start-up easy for you. These batteries may not
last as long as new batteries may. When you have to replace the batteries on the outdoor sensor,
we recommend you use alkaline batteries. One advantage of this type of battery is better perform-
ance when the outside temperature falls below 0°C (32°F). For optimal performance, we recom-
mend lithium batteries.
• Avoid using rechargeable batteries. Rechargeable batteries do not maintain correct power require-
ments.
• First, insert the batteries into the base station, and then insert the batteries into the outdoor sensor.
• Insert batteries before fi rst use, matching the polarity indicated in the battery compartment.

OPERATION

Immediately after batteries are installed, the outdoor sensor will start transmitting temperature data to
the base station at regular intervals. Once the base station is powered up by inserting the batteries,
the display will show all available LCD segments for a moment.
Important:
After this, the base station will scan the outdoor sensors (channel 1 to channel 3) in the TEMPERA-
TURE window. There is no need to press any button during this process. After this, the base station
will start to scan the DCF77 time transmitter in the CLOCK window. The default time the base station
starts with is 12:00, which will be automatically reset during this process. There is no need to press
any button during this process either.
Recommendation:
Allow the base station to receive the outdoor sensor's data and the time without touching any button
for about 6-8 minutes during the base station's initial set up. This will give the base station time to
synchronize with the sensors, stabilize pressure readings and attain default settings.
