Question about Emerson Smartset Clock Radio
I received this clock as a Christmas gift. It's only mid-February and its already lost 5 minutes.
This is a problem with either the a/c power or the Clock/Radio's internal timing crystal circuitry. The radio depends on the 60 cycle power source as the timing device. If this power is irregular or uneven in its delivery it can cause the timing circuits to lose or gain time. The Clock/Radio has a frequency tuned crystal that operates like the second hand on a clock. When the calibration for whatever reason is lost the crystal will not be able to perform the timing function correctly. The reason this does not happen in all Clock/Radios is that they usually have correction circuits. These circuits keep the crystal from drifting out of calibration during operation. Because of the low production cost of these Clock/Radios, the quality control is almost non existent. The components are variable and sometimes they do not stay within specifications. This problem is usually handled by quality control departments in the manufacturers facilities. They usually test a certain amount of the production run to make sure it meets specification. In higher priced electronics these test are on going during the production run. In lower cost electronics these tests for quality control are usually done before the production run. This is to choose the best and most reliable components for the price level of the product in production. What this means to you, is that the quality of the components and quality control of the production runs are based on cost efficiency to the manufacturer. This is the reason for these type of efficiency variables in the products. The customer support telephone number for Emerson is 1-800-898-9020 between the hours of 9am-5pm CT. Give them the make and model number of the Clock/Radio and ask them for assistance with your problem. I hope this information helps you under the problem and reason these problems can occur in the products. Thank you for using FixYa and have a nice day.

To set up your clock simply install one fresh AA, LR6 ALKALINE battery. Due to the nature of long wave radio signals it is normally not possible to receive a signal during the day so it is best to install the battery late in the evening. Select your time zone by pressing one of the four time zone buttons PT-Pacific Time, MT-Mountain Time, CT-Central Time, ET-Eastern Time. The time zone buttons may be pressed any time after installing the batteries. If multiple buttons are pressed the clock will set to the time zone selected last. If no time zone is selected the clock will default to Pacific Time. Another time zone can be selected during or after the clock has set itself. Your clock can only set itself to one of the four time zones stated above. For time zones outside of PT, MT, CT or ET you must manually set the time using the Manual Time set button on the back of the movement.
When the battery is installed the second hand will advance eight seconds (two seconds per step x four steps). The clock is now searching for a signal. For the initial setting it is recommended to stand the clock in an upright position near a window. Within five minutes the clock will either receive the WWVB signal and set itself to the exact time, or it will determine that the signal is not receivable at its current location and time of day. If a signal is not receivable it will fast-forward the hands to the 4, 8, or 12 o'clock position and search for WWVB each
hour until a signal is received. If the time is manually set the clock will continue to periodically search for a signal and automatically reset the hands when the signal is received.
Select a location to place your radio controlled clock where it will be at least six feet away from a TV, computer, air conditioner or other household electrical appliances. The optimal location is near a window. Windows facing Colorado providing the best signal. The WWVB time signal will easily penetrate Masonry and wood framed buildings. WWVB will penetrate almost every residential building and most steel buildings if they have adequate windows. It is not possible, however, for WWVB to penetrate most indoor shopping malls and rooms in the center of large office buildings that do not have windows. In buildings that WWVB cannot penetrate you may set the time using the manual time set button. When the clock is exposed to the WWVB signal it will automatically set the hands to the exact time. OK.
