BATTERIES

Explanation: Many problems are resolved with fresh batteries of the appropriate voltage.

Many items sent in under warranty work when tested with fresh batteries. Batteries

manufactured this year will have an expiration date 10 years (or more) in the future. Battery

technology has improved and batteries will maintain voltage longer in storage. However,

the environment the batteries reside in for the 10 years can deplete the power.

• We suggest a name-brand Alkaline battery.

• A minimum voltage of 1.48V is necessary for proper performance.

• Use a battery dated at least six years in advance of the current year. Batteries dated

earlier than six years from now may still work, but may be unstable in performance.

• Good name-brand batteries make less noise, which reduces the chance of RF (radio

frequency) interference from the battery compartment.

ATOMIC CLOCK FACTORY RESTART Explanation: The factory restart returns the atomic clock to an “out-of-the-box” state and often resolves an issue. Factory Restart: 1. Remove the battery from the clock for 15 minutes. 2. Press the Manual Set Tab at least 20 times to clear all memory. 3. Insert fresh Alkaline battery into the clock. 4. The hands will spin to 12:00, 4:00 or 8:00 and wait for the WWVB time signal.

• • Check for fresh batteries. Without proper batteries, the antenna will have a harder time picking up the signal. Position the atomic clock in a window (with the front or back) facing Ft. Collins, Colorado and leave for up to five nights. If you do not have a window facing this direction, position the clock near an outside wall and point the unit in this general direction. MANUALLY SET TIME 1. Remove battery for 15 minutes and press the Manual Set Tab 20 times. 2.

HANDS SPIN NON-STOP • • • This is indicative of a low or overpowered battery (number 1 warranty issue). Replace battery and perform restart procedure. Allow 5 days to catch the WWVB signal If constant spinning continues, the movement may need replacement. HANDS JUMPS OR JERKS AROUND THE DIAL • • • This is indicative of a low or overpowered battery (number 1 warranty issue). Replace battery and perform the restart procedure. Allow up to 5 days to receive a signal.
