Power Supply; Reception Of Radio Controlled Time Signal - National Geographic 9070500 Bedienungsanleitung

When changing batteries always change batteries in the
main unit as well as all remote units and replace them in the
correct order, so the remote connection can be re-established.
If batteries are exchanged in only one of the devices (i.e. the
remote sensor) the signal can't be received or can't be received
correctly.
Note, that the effective range is vastly affected by building
materials and position of the main and remote units. Due to
external influences (various RC devices and other sources of
interference), the maximum distance can be greatly reduced. In
such cases we suggest to position the main unit and the remote
sensor at other places. Sometimes all it takes is a relocation of
one of these components of a few inches!
Though the remote unit is weather proof, it should be placed
away from direct sunlight, rain or snow.

POWER SUPPLY

Main station
1. Put the DC power plug (Fig. 1, C) in the DC jack (Fig. 2, 18).
2. Push the RESET knob to initialize the automatic time signal
and remote sensor signal seanning.
3. Open the battery compartment covering carefully with a coin
(turn to arrow direction OPEN).
4. Insert 1 button cell (Typ CR2032, 3V) according to the polarity
marked in the battery compartment.
5. Close the battery compartment.
NOTE!
1. If no signals are received or the transmission is interfered, ‚---'
will appear on the LCD.
2. Position the receiver and transmitter within the effective
transmission range: 30m in usual circumstances.
3. If the device is running on battery power, only a minimum
power supply is guranteed. The display is working on lowest
level, projection and color change function are not available
in low battery mode.
Remote sensor
1. Open the battery compartment covering carefully.
2. Install 2 batteries (AA size 1.5V) strictly according to the
polarities shown.
4. Reinsert the battery compartment door.
NOTE!
Once the channel is assigned to one transmitter, you can only
change it by removing the batteries or resetting the unit.
