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:
"OFL“ 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 transmitter or place the transmitter
closer to the Atomic Clock. Make sure the clock is at a receivable range
from the transmitter.
3) Move the units to another location. Interferences from other electrical
devices operating on the same signal frequency (433MHz) may prevent
correct signal transmission and reception.
Problem:
"OFL“ 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 transmitter.
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.
