Digital Clock Factory Restart

Explanation:

The factory restart returns the digital clock to an “out-of-the-box” state and often

resolves an issue.

Factory Restart:

1. Remove AC cord and batteries from the digital clock.

2. Press one of the buttons on the digital clock at least 20 times to clear all memory.

3. Verify that the digital clock is blank before proceeding (some lines are painted on and will not

disappear).

Leave without power for 15 minutes

(very important).

5. Insert AC power into the wall than into the digital clock.

6. Do not press buttons for 15 minutes.

like a quartz clock.

How do I change Language?

This clock will display weekday and month in English or Spanish.

Use the Program Menu to select language

Does the clock have a backlight?

When operating with the AC adapter, the backlight is adjustable: (HI-LOW-OFF).

Press and release the SNOOZE/LIGHT HI-LOW-OFF button to adjust backlight.

When operating on batteries only, the backlight will come on briefly when the SNOOZE button

is pressed.

Time is off by hours

Check to see if the WWVB Tower icon appears on the atomic digital clock. If not, the digital

clock has not received a WWVB time signal in the past 24 hours.

Reposition the digital clock with the front or back facing Colorado.

Check that the Time Zone selected correctly reflects your location. Adjust the time zone in the

Program Menu.

Check that the DST indicator is correct for your location (On this clock, please change the DST

setting to OFF unless you live in Arizona). Adjust the DST indicator in the Program Menu.

Large buildings, metal roofed buildings and buildings or rooms full of electrical and/or radio

equipment make it difficult to receive the WWVB time signal.

Daylight Saving Time

Dependent on your location, position of the clock in your home, and atmospheric interference,

it may take up to 5 nights for the change from Daylight Savings Time to Standard Time and

vice-versa to occur.

Check for a WWVB Tower Icon showing on the atomic digital clock. The tower icon indicates

you have received the WWVB signal from Ft Collins CO in the past 24 hours.

Check that the clock is in the correct Time Zone.

Check whether the DST indicator is ON or OFF. On this clock, please change the DST setting

to OFF unless you live in Arizona.

Check for fresh batteries. Without proper batteries, the antenna will have a harder time

picking up the signal.

Position the digital 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.
