The Chaney 75071 Extra Large Digital Wall Clock automatically displays the correct time from the moment you insert batteries and select your time zone. It continues to display the correct time even after battery changes. It also springs ahead and falls back automatically when the Daylight Saving Time (DST) change occurs twice a year. No adjustment by the user or detection of an external signal by the clock is ever needed for DST changes. Best of all, the hour and minute digits on this clock are 4 inches tall and extra bold, and the seconds digits are just under 3 inches tall and quite bold as well. (Yes!!! Finally!! Big seconds digits!) If you need a not-too-large, no-frills digital clock that can be viewed from across a large room or workspace, or if you or someone you know is visually impaired, the Set & Forget 75071 is one clock you should definitely consider.

Talk about super-easy setup! Simply insert four AA alkaline batteries. The clock takes it from there. An integral microchip that is pre-programmed with a calendar sets the clock instantly to the default Eastern zone time. All you need to do after inserting batteries is select your time zone (choices are Atlantic, Eastern, Central, Mountain, Pacific, Alaska, and Hawaii-Aleutian) and set a switch for Old DST (year 2006) or New DST (year 2007 and later). If you live in a location that does not observe DST, you can set the DST switch to OFF to disable the time changes. Down the line, the microchip tells the clock the exact days and times on which to change to DST in the spring and back to standard time in the fall and which years are leap years. No signals or antennas are required!'

The Chaney 75071 displays the time in 12-hour mode with AM and PM. Along with the time, this clock displays the selected time zone and, if DST is in effect, displays "Daylight ST" as well.

As mentioned above, the 75071 is powered by four AA alkaline batteries. These are not included and must be obtained separately. Although their expected life is not specified, we expect it to be about one year. You also need to know that the included and preinstalled CR2032 button cell battery that powers the time and calendar microchip needs occasional replacement. With the four AA batteries installed, the CR2032 battery should be replaced every three years. If AA batteries are not installed (for example, if the clock is stored), replace the CR2032 battery every 2 years. Here's the important thing: Never remove all of the batteries at the same time because the internal calendar memory (Set & Forget functions) will no longer function properly. When replacing the CR2032 battery, make sure that the AA batteries are installed and that the time display is operational.

If you wish to set the time forward or back from the actual time, manual time set capability lets you do so. This feature also lets you reset the clock (including the memory) if all batteries are accidentally removed or if you forget to change the CR2032 battery and it wears out. If the clock ever performs abnormally, you can use a small object such as a paper clip to press the recessed RESET button on the back of the clock. You then perform the manual time set procedure to set the clock to the correct time and date.

The movement in this clock is a highly accurate digital quartz movement (but not "atomic"). Although accuracy is not specified in the instructions, movements of this type are typically accurate to +/-15 to +/-30 seconds per month. Also, this clock has no alarm, and, as is typical of digital clocks with large displays, its display is not illuminated.

On the back of the clock are three keyhole slots for wall mounting and two fold-out table stands for free-standing use. For viewing from a distance or for people with imperfect vision, the jumbo display Chaney 75071 may be the perfect clock. 

Note: At the time of this writing, the U.S. Congress has passed legislation that will lengthen Daylight Saving Time in 2007 by starting it earlier and ending it later in the year. This clock can be optioned to change time on the old dates (2006) or on the new dates (2007 and later).

Features:

• Clock automatically displays Eastern zone time when the batteries are inserted. All you need to do is select your time zone and either Old DST (2006) or New DST (2007 and later).
• Clock automatically resets twice per year for DST. The DST time changes can be disabled for areas that do not observe DST.
• Time is displayed as hour, minutes, and seconds in 12-hour mode with AM or PM.
• Hour and minute digits are extra bold and 4 inches tall. Seconds digits are 2-7/8 inches tall and very bold as well.
• Selected time zone (Atlantic, Eastern, Central, Mountain, Pacific, Alaska, or Hawaii-Aleutian) is displayed along with time.
• If DST is in effect, "Daylight ST" is displayed below the time zone.
• Calendar dates are pre-programmed through December 31, 2029.
• Manual time and calendar setting is possible (for example, for a time offset either forward or back from actual time).
• Molded case is metallic silver-tone with a gray Set & Forget logo below display.
• Clock batteries: four AA (1.5V) alkaline batteries (not included), with expected life of approximately 1 year.
• Calendar memory battery for Set & Forget functions: one CR2032 (3V) lithium battery (included and preinstalled), with expected life of up to 3 years (see clock instructions).
