Instructions for Centrios Atomic Clock

Answer 1

This didn't work for me. Here's what worked for my Centrios Atomic Global travel alarm clock with dual time:

A. Set time zone to "US".

1. In regular time mode (not alarm or dual time modes), press and hold "Set" until the tiny country code, indicating time zone, starts blinking either "JP", "US", "GB", or "DE" for Japan, US, Great Britain, or DEutschland/Germany, respectively.

2. Press "Adjust" repeatedly until "US" is blinking.

3. Press "Set" and the "US" will stop blinking and turn solid.

4. Now you can set the language by pressing "Set" repeatedly to cycle through "GB" for English, "FR" for French, "DE" for German, "ES" for Spanish, and "IT" for Italian.

5. Press "Mode" to return to normal clock mode.

B. Set the specific US time zone.

1. In normal clock mode (NOT alarm or "dual" time modes) displaying the day of the week (such as "WED" for Wednesday), press and release (don't hold) "Set".

2. The day of the week should BRIEFLY change to "PA" in large letters in the upper left, indicating the default Pacific time zone. This will quickly revert to the day of the week! You can leave the Pacific time zone selected, or go to the next step.

3. Before the "PA" disappears, quickly press "Adjust" repeatedly to cycle among "MO", "CE", "EA", and back to "PA", for MOuntain, CEntral, EAstern, and PAcific time zones, respectively. Stop when you reach the desired time zone.

4. After a second or two, the US time zone will revert to the day of the week.

5. Press "Receive" to try to get the time code signal from WWVB in Fort Collins, Colorado, USA. The station is operated by the US government and continuously transmits a low-frequency code that radio-controlled clocks like the Centrios "Atomic Global" travel alarm use to automatically set the time.

6. The time code takes a full minute to transmit/receive, so it can take some time for the clock to set itself. The signal is clearer at night and during cold weather, so be patient. It might help to place the clock over night in a window roughly facing Colorado.

Getting Started

1. Remove the battery door by slightly pressing the knob upward.

2. Insert one new AA size battery as per indication marked in the

battery compartment.

3. Close the battery door.

4. When the battery is inserted, all the segments of the display

will be shown briefly before entering the radio controlled time

reception mode.

5. The RC Clock will automatically start scanning for the radio

controlled time signal after 15 seconds.

6. The default time zone is Pacific time zone. If you are in this

time zone, changing is not required. Otherwise, change to the

Signal Strength Indicator

The signal indicator displays signal strength in 3 levels. Wave

segment flashing means time signals are being received. The

signal quality could be classified into three types:

Poor signal quality Acceptable signal quality

Excellent signal quality

If the clock receives the signal successfully, a solid signal strength

symbol appears on the display.

The unit has already received the time signal. Otherwise the

signal strength symbol disappears from the LCD display.

NOTE: You may use the RECEIVE button to receive the time

signal manually. The receive mode stops automatically after 6-12

minutes. The receive mode consumes more battery power and will

reduce the battery lifetime.
