6.  
After the clock receives the outdoor temperature the WWVB time code reception will  
automatically start. The clock will automatically set itself to the exact time, day and  
date after receipt of the WWVB time code reception. This typically takes over night.  
For best reception place your clock next to a window facing Colorado over night. Once  
a successful reception is received the Radio Reception (  
) icon will appear above  
the blinking colons. Once a successful reception is received relocate your clock to a  
desired location. The clock will then automatically attempt to receive the WWVB time  
from 12:00 am through 6:00 am each day (attempts WWVB reception every full hour  
within this time frame). When this is successful, the received time will override the  
manually set time. The date is also updated with the received time (Please refer to  
notes on “Manual time setting”).

OUTDOOR TEMPERATURE TRANSMITTER:  
The temperature is measured and transmitted to the radio-controlled clock every 1 minute.  
The radio-controlled 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 radio-controlled clock will receive the temperature data within 15 minutes. If the  
temperature data is not received 15 minutes after setting up (the display shows “- - -”), then  
please check the following points:  
1.  
The distance of the radio-controlled clock or outdoor temperature transmitter should be  
at least 6 feet away from any interfering sources such as computer monitors or TV  
sets.  
2.  
3.  
Avoid placing the receiver onto or in the immediate proximity of metal window frames.  
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.  
11  
Note:  
When the 433 MHz signal is received correctly, do not re-open the battery cover of either the  
outdoor temperature transmitter or radio-controlled 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 from the outdoor temperature transmitter to  
the radio-controlled 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). See our website  
POSITIONING  
Before permanently mounting ensure that the radio-controlled clock is able to receive  
WWVB signals from the desired location. Also, extreme and sudden changes in temperature  
will decrease the accuracy of the radio-controlled 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.  
POSITIONING THE RADIO-CONTROLLED CLOCK:  
There are 2 possible ways to mount the radio-controlled clock:  
use of the foldout table stands, or  
wall mounting  
FOLDOUT TABLE STAND  
The foldout table stand legs are located on the lower section of the backside of  
the radio-controlled clock. Pull the stands out from the bottom center edge,  
below the battery compartment. Once the foldout table stands are extended,  
place the radio-controlled clock in an appropriate location.  
Foldout table stand leg  
12  
WALL MOUNTING  
1) Using a straightedge, horizontally space at 2.36 inches (60 mm) 3  
screw positions on a wall.  
2) Install 3 mounting screws (not included) into a wall within  
transmission range—leaving approximately 3/16 of an inch (5mm)  
extended from the wall.  
3) Place the radio-controlled clock onto the screws, using the hanging  
holes on the backside. Gently pull the radio-controlled clock down to  
lock the screws into place.  
Note:  
Always ensure that the radio-controlled clock locks onto the screws  
before releasing.  
POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER  
To achieve a true temperature reading, avoid mounting where direct sunlight can reach the  
outdoor temperature transmitter. It is recommended to mount the outdoor temperature  
transmitter on a North-facing wall or in any well-shaded area. The maximum transmitting  
range is 330 feet obstacles such as walls, concrete, and large metal objects can reduce the  
range.  
Place both units in their desired location, and wait approximately 15 minutes before  
permanently mounting to ensure that there is proper reception. The outdoor temperature  
transmitter is not waterproof and should not be placed anywhere it will become submerged  
in water or be directly in the rain.  
The outdoor temperature transmitter can be mounted in two ways:  
with the use of screws, or  
using the adhesive tape.  
MOUNTING WITH SCREWS  
1)

electrical devices operating on the same signal frequency (433MHz)  
may prevent correct signal transmission and reception.  
"OF.L“ appears in the outdoor temperature section of the LCD.  
1) Wait until the current surrounding temperature cools down or  
increases. Current temperature is outside of the measuring range of  
the transmitter or has temporary affected battery strength. The  
outdoor temperature will be displayed again once the current  
surrounding temperature is within the range of the transmitter.

CARE AND MAINTENANCE:  
Avoid placing the units in areas prone to vibration and shock as these may cause  
damage.  
Avoid areas where the units can be exposed to sudden changes in temperature, i.e.  
direct sunlight, extreme cold and wet/moist conditions as these will lead to rapid changes  
which reduces the accuracy of readings.  
When cleaning the LCD and casing, use a soft damp cloth only. Do not use solvents or  
scouring agents.  
Do not submerge the units into water.  
Immediately remove all low powered batteries to avoid leakage and damage. Replace  
only with new batteries of the recommended size.  
Do not make any repairs to the units. Please return it to the original point of purchase.  
Opening and tampering with the units may invalidate the warranty.
