This atomic wall clock
features large bold digits, especially those for the indoor and outdoor
temperature, which are 1-1/2 inches tall (except for tenths of
a degree, which are smaller).
The hour and minute
digits are 1 inch tall, and seconds are 1/2 inch tall.
The month, date, and year (all displayed digitally) are 3/4 of an inch
tall. A remote
sensor/transmitter that reports the outdoor temperature to the clock for
display is included.
Prominently displayed in the center of the display
is a weather forecast icon. This self calibrating weather forecaster
analyzes it's environment in order to give you a forecast with superior
accuracy. Based on barometric pressure changes and outdoor temperature,
the forecaster displays a weather prediction for the next 12 to 24
hours.
You'll appreciate
the both the absolute accuracy and the useful features of
the 75321
Worthington
clock. Because this clock is atomic,
it sets itself automatically and adjusts automatically twice a year for
Daylight Saving Time (DST). If you live in a location that does not
observe DST (Arizona and parts of Indiana), you can easily disable the
DST time change function. Also, you can disable automatic setting of
time and date and set the clock manually if you wish (for example, if
you take the clock out of WWVB time signal range). The time can be displayed in 12-hour or 24-hour
mode. Calendar information is
pre-programmed from 1 January 2000 through 31 December 2099. Month,
date, and year are displayed digitally. Successful
reception of the time-synchronization radio signal from Colorado
is indicated
by a radio tower and waves icon, just above the weather forecast
icon. After synchronization occurs, you can
select your continental U.S. time zone (EST, CST, MST, or PST) by means of a switch on
the back of the clock.
The indoor
and outdoor temperatures can be displayed in
either
°F or °C, and both the
temperature unit and the 12-/24-hour time mode can be changed at
any time during normal operation simply by pressing buttons on
the back of the clock. You don't have to reinitiate clock setup to do this. Also, if you
live in an area that does not observe Daylight Saving Time
(Arizona and parts of Indiana), you can simply set a switch on
the back of the clock to disable automatic DST changes in the
spring and fall.
With the 75321 clock, you
install batteries in the clock first and then in the remote. You then press
the Tx (transmit) button on the remote. When reception occurs, the clock
logs the remote in as Channel 1. Channels 2 and 3 register in the
same way if additional sensors are purchased and used. The remote
sensors can transmit up to 100 feet (30 meters) without outside
interference, i.e., in an open area. The
clock requires three AA (1.5V) alkaline batteries for powering, and the
remote uses two AAA (1.5V) alkaline batteries. The batteries are not
included and must be obtained separately. Now that AAA lithium batteries
are available, you may want to try them in the remote when temperatures
are expected to fall below freezing. Based on past experience,
we believe that the outdoor temperature measuring range specification
below assumes the use of alkaline batteries in the remote. A
low-battery icon to the left of the time display digits indicate that
the clock's batteries need replacement, and a flashing outdoor
temperature tells you that the remote for the indicated channel needs
its batteries replaced. The
75321 can be mounted on a wall, or you can extend the folding legs
and place the clock on a table or shelf. Either way, this clock will
look good while providing you with valuable time and temperature
information..
