EXIT THE MANUAL SETTING MODES
To return to the normal display mode from anywhere in manual setting mode simply press the
SNOOZE
key
anytime.
If no keys are pressed for at least 15 seconds in setting mode, the Atomic Clock will automatically switch back to
normal display mode.
ALARM SETTING
To enter into the alarm setting mode:
1.
Hold the
ALARM
key for 2 seconds. The hour digits start flashing.
2.
Press the + key to set the hour.
3.
Press the
ALARM
key to set the minutes. The minute digits start flashing.
4.
Press the + key to set the minutes.
5.
Press again the
ALARM
key to exit the Alarm setting mode or wait for 15 seconds automatic timeout.
TO DEACTIVATE THE ALARM:
The alarm will be automatically ON. To deactivate the alarm (OFF), press once the
ALARM
key in normal mode
display.
SNOOZE SETTING
The snooze can only be activated during alarm time for a snooze duration of 10 minutes.
OUTDOOR TEMPERATURE TRANSMITTER:
The temperature is measured and transmitted to the SkyScan 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.
433MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER
The Atomic Clock will receive the temperature data within 4 minutes. If the temperature data is not being 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 82 feet (25 meters) from the Outdoor Temperature Transmitter to the Skyscan
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
).
POSITIONING
Note:
Before permanently mounting ensure that the Skyscan Atomic Clock is able to receive WWVB signals from the
desired location. Also, extreme and sudden changes in temperature will decrease the accuracy of the Atomic Clock,
and changes in elevation will result with inaccurate temperatures readings for the next 12 to 24 hours. These changes
will require a 12 to 24 hour wait before obtaining reliable data. To achieve a true temperature reading, avoid
mounting where direct sunlight can reach the OutdoorTemperature Transmitter. It is recommended to mount the
Outdoor Temperature Transmitter on a North-facing wall. The maximum transmitting range is 82 feet (25 meters)
obstacles such as walls, concrete, and large metal objects can reduce the range. Place both units in their desired
location, and wait approximately 10 minutes before permanently mounting to ensure that there is proper reception.
