Before Commissioning; Setting Up Power Supply - National Geographic VA 9070700 Bedienungsanleitung

7 Before commissioning

NOTICE
Avoid connection faults!
In order to avoid connection problems between the devices, the following points must be observed
during commissioning.
1. Place the base unit (receiver) and sensor (transmitter) as close together as possible.
2. Connect the power supply to the base unit and wait until the indoor temperature is displayed.
3. Establish power supply for the sensor.
4. Set up/operate the base unit and sensor within the effective transmission range.
5. Make sure that the base unit and the radio sensor are set to the same channel.
When changing the batteries, always remove the batteries in both the base unit and the sensor and
reinsert them in the correct order so that the radio connection can be re-established. If one of the two
devices is operated via a mains power connection, the power connection for this device must also be
disconnected briefly when changing the battery. If, for example, only the batteries in the sensor are re-
placed, the signal cannot be received or can no longer be received correctly.
Note that the actual range depends on the building materials used in the building and the position of
the base unit and outdoor sensor. External influences (various radio transmitters and other sources of
interference) can greatly reduce the possible range. In such cases, we recommend finding other loca-
tions for both the base unit and the outdoor sensor. Sometimes a shift of just a few centimetres is
enough!

8 Setting up power supply

Base device
1. Insert the DC connector into the connection socket of the base station.
2. Insert the mains plug into the power outlet.
3. The device is energized directly.
4. Wait until the indoor temperature is displayed on the base station.
NOTICE! For permanent operation, mains power supply is recommended. Alternatively a
power supply with batteries is also possible, to keep the time setting in case of power fail-
ure. Proceed as follows:
5. Remove the battery compartment cover.
6. Insert the batteries into the battery compartment. Ensure that the battery polarity (+/-) is correct.
7. Replace the battery compartment cover.
8. Wait until the indoor temperature is displayed on the base station.
NOTICE! When switching from mains power supply to battery power supply or vice versa,
the power supply is being disabled for a short moment for technical reasons. Exception: per-
manent battery operation.
Remote sensor
9. Remove the battery compartment cover.
10. Insert the batteries into the battery compartment. Ensure that the battery polarity (+/-) is correct.
11. Set the channel selector switch to the desired channel.
NOTICE! This weather station can be operated with one or more remote sensors. Each re-
mote sensor being connected must be operated on a different channel. If only one remote
sensor is connected, it should be operated on channel 1.
