SNOOZE SETTING
The snooze can only be activated during alarm time for a snooze duration of 10 minutes by
pressing the SNZ key on the back of the clock.
OUTDOOR TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the atomic clock every 1 minute. The atomic
clock will update the temperature display every 5 minutes.
The range of the outdoor temperature transmitter may be affected by the temperature. At cold
temperatures the transmitting distance may be decreased. Please bear this in mind when
positioning the transmitter. Also the batteries may be reduced in power during periods of extreme
cold temperatures.
433MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER
The atomic clock will receive the temperature data within 4 minutes. If the temperature data has
not been received 4 minutes after setting up (the display shows “- - -”), then please check the
following points:
1. The distance of the atomic clock or outdoor temperature transmitter should be at least 6 feet (2
meters) away from any interfering sources such as computer monitors or TV sets.
2. Avoid placing the receiver onto or in the immediate proximity of metal window frames.
3. Using other electrical products such as headphones or speakers operating on the same signal
frequency (433MHz) may prevent correct signal transmission and reception.
4. Neighbors using electrical devices operating on the 433MHz signal frequency can also cause
interference.
Note:
When the 433 MHz signal is received correctly, do not re-open the battery cover of either the
outdoor temperature transmitter or atomic clock, as the batteries may spring free from the
contacts and force a false reset. Should this happen accidentally then reset all units (see
Setting
up
above) otherwise transmission problems may occur.
The maximum transmission range is 330 feet (100 meters) from the outdoor temperature
transmitter to the atomic clock (in open space). However, this depends on the surrounding
environment and interference levels. If no reception is possible despite the observation of these
factors, all system units have to be reset (see
Setting up
).
