• Replace battery annually or when the clock cannot receive the
atomic signal.
• Keep clock clean, dry and dust-free by cleaning it regularly with
a soft cloth.
• Do not use corrosive cleaners or chemicals on the clock.
• Always store the clock without a battery when not in use.
Mount the Clock
• Utilize the hanger molded into the backside of the clock for wall
mounting.
• Use a securely anchored screw, nail or hook to support the
weight of the clock.
• Ensure the mounting screw/nail head is large enough to secure
the clock and it from slipping off in the event that it is bumped.
Outdoor Use
This only applies to clocks that are labeled for outdoor use.
• Extended periods of cold temperatures (below -4ºF / -20ºC) can
cause alkaline batteries to function improperly. Use lithium
batteries in low temperatures to ensure continuous operation of
the clock.
• To extend the life of the clock, place in an area protected from
direct weather elements.
TROUBLESHOOTING
Problem
Possible Solution(s)
Poor Signal
• Place clock near a window with the
curtains or blinds open to improve signal
reception.
• Place clock more than 3 ft away from
electronics or wiring to minimize
interference. Electronics (computers,
TVʼs, fluorescent lights, microwaves, etc.)
can interfere with signal reception.
• If you do not find good reception on
your first attempt, try again later.
Reception may be impacted by the
weather, season, time of day and solar
activity. The best reception is typically at
night just before/after sunrise and sunset.
In areas and times of very poor
reception, it may take a few days before
the signal can be received.
• On rare occasions the atomic signal
WWVB transmitter is turned off for repair
or maintenance.
Clock will
not synchronize
• Insert a new 1.5 volt “AA” battery
• Take the clock outside on a clear night
and remove the battery. Power it up by
reinserting the battery, which will force it
to search for the atomic signal again. If
the clock works outside but not inside,
you may have an indoor interference
problem.
