TROUBLESHOOTING: 

 

Problem: 

The LCD is OFF. 

Solution: 

1) Move the solar clock to a brighter 

environment. 

2)  Check that the solar panel is not 

covered. 

3)  Replace the battery if using alkaline 

battery. 

4)  Enter program menu and turn Solar 

Mode OFF (this is a power saving 
feature). 

Problem: 

No reception of WWVB signal 

Solution: 

1)  It may help reception to face the front of 

the radio-controlled clock in the general 
direction of Ft. Collins, Colorado. 

2)  Wait overnight for signal. 
3)  Be sure the radio-controlled clock is at 

least 6 feet (2 meters) from any electrical 
devices, i.e. TV sets, computers, or other 
radio controlled clocks. 

4)  Remove batteries for five minutes, 

reinsert and leave the unit alone overnight 
without pressing any keys. 

Problem: 

Hour is incorrect (minute and date are 
correct). 

Solution: 

1) Be sure the correct time zone and daylight 

saving time is selected. 

Problem: 

"OFL“ appears in the indoor temperature 
section of the LCD 

Solution: 

1)  Move the radio-controlled clock to an 

area with warmer or cooler surrounding 
temperature. Current surrounding 
temperatures are outside measuring 
range. Batteries. 

Problem: 

"00" appears in the in humidity section of 
the LCD. 

Solution: 

1) Remove the battery from the unit for ten

Solution:

Remove the battery, slide the battery switch 

to BATTERY and reinsert the the 
battery.  

If you are using a rechargeable battery, you 

can then slide the battery switch to 
SOLAR. 

 
CARE AND MAINTENANCE: 

 

Avoid placing the unit in areas prone to vibration and shock as 
these may cause damage. 

 

Avoid areas where the unit 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 
reduce 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 unit into water. 

 

Immediately remove all low powered batteries to avoid 
leakage and damage. Replace only with new battery of the 
recommended size. 

 

Do not make any repairs to the unit. Please return it to the 
original point of purchase. Opening and tampering with the 
unit may invalidate the warranty.
