Atomic Projection Alarm Clock
La Crosse Technology WT-5120U displays very accurate
temperature, indoor humidity (rare in a projection clock), plus outdoor temperature on it's large LCD
display In addition, the WT-5120U projects an alternating pattern
of time and outdoor temperature on the ceiling or wall.
The La Crosse WT-5120U is attractively finished in silver
with black trim.
Of course, like all La Crosse Atomic
Clocks, the WT-5120U receives timing information from the U.S.
Atomic Clock source, transmitted by the U.S. Commerce
Department's transmitter near Boulder Colorado. You
know the time will always be accurate, plus, the time can automatically adjust for Daylight Savings Time.
Outdoor temperature information
is transmitted to the WT-5120 by the included TX6U transmitter,
which can be placed outdoors up to 80 feet away.
The time and temperature
projection display projects continuously when the included AC
adapter is used.
The front LCD display has LED
backlights that can be momentarily illuminated by depressing the
snooze button. When operating on batteries alone (without
the AC adapter), touching the snooze button also activates the

Note: This clock is
intended for use in the 48 contiguous U.S. States, and
Southwestern Canada. Outside of this area, the clock can
be set manually, but the signal will likely be too weak to
reliably set the clock.
Like all Atomic clocks, the auto
setting feature relies on the reception of a radio signal.
This signal can be interfered with by computers, lamp dimmers,
other sources of electronic noise, bad weather conditions, and
certain types of building construction. In most locations,
the signal will be received often enough that the time display
will remain quite accurate. There is a possibility,
however, that DST time changes may not occur immediately if the
location or weather are unfavorable.
