5) 

Position the remote temperature sensor in the desired location, 
ensuring that the atomic clock can receive the signal. 

 

Note:

  Mounting with adhesive tape is not recommended as a permanent 

mounting solution.  Only use the adhesive tape during set-up process. 

 

TROUBLESHOOTING 

 

Problem: 

The LCD is faint. 

Solution: 

1)   Replace the batteries. 

Problem: 

No reception of WWVB signal 

Solution: 

1)  It may help reception to face the front of the atomic clock in the general 

direction of Ft. Collins, Colorado. 

2)  Wait overnight for signal. 
3)  Be sure the atomic 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 are selected. 

Problem: 

"OF.L“ appears in the indoor temperature section of the LCD 

Solution: 

1)  Move the atomic clock to an area with warmer or cooler surrounding 

temperature. Current surrounding temperatures are outside measuring 
range. 

Problem: 

"--.-" appears in the outdoor temperature section of the LCD. 

Solution: 

1)  Remove the batteries of both units for one minute, then reinsert them 

again. Make sure the batteries are new and fresh. 

2)  Move the atomic clock closer to the sensor or place the sensor closer to 

the atomic clock. Make sure the clock is at a receivable range from the 
sensor. 

3)  Move the units to another location. Interferences from other electrical 

devices operating on the same signal frequency (915MHz) may prevent 
correct signal transmission and reception.  

Problem: 

"OF.L“ appears in the outdoor temperature section of the LCD. 

Solution: 

1)  Wait until the current surrounding temperature cools down or increases. 

Current temperature is outside of the measuring range of the sensor. The 

 

14

outdoor temperature will be displayed again once the current surrounding 
temperature is within the range of the sensor. 

 

 

MAINTENANCE AND CARE INSTRUCTIONS 

 

Extreme temperatures, vibration, and shock should be avoided to prevent damage to the 
units. 

 

Clean displays and units with a soft, damp cloth.  Do not use solvents or scouring agents; 
they may mark the displays and casings.  

 

Do not submerge in water. 

 

Immediately remove all low powered batteries to avoid leakage and damage. 

 

Opening the casings invalidates the warranty.  Do not try to repair the unit.  Contact La 
Crosse Technology for repairs. 

 

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.
