7 MAIN UNIT FEATURES

Radio-controlled Clock : The unit starts synchronizing the clock after the 1st channel of the wireless sensor begins to send its information to the main unit. (This is called registration.) The built-in antenna receives the official time signal from the US Government's National Institute of Standards and Technology. A microchip translates the time signal and adjusts the time display for the correct time, and date.

Manually Setting the Time and Date:

1)Press and hold the “SET” button, and the year display will flash on the screen. Using the “+” and “– ” buttons set the year. When the correct year is entered, press and release the “SET” button to confirm the setting.

2)Once you have confirmed the year, follow the same procedure to set the month, date, hour, minute, 12 or 24-hour time preference, and DST (Daylight Saving Time).

NOTE: You cannot change any settings manually if the clock is attempting to synchro- nize. Allow the clock to finish the cycle, and then manual changes can be made if the clock has not automatically acquired the signal and set itself to the correct time.

Time Zone:

Note: Default setting is Pacific Time. If you live outside of the Pacific Time Zone, you will need to set your Time Zone using the following procedure:

1)Press and hold the “– /C/F” button on the front of the clock for three seconds. The area of the clock where the seconds are usually displayed will be replaced with the letter for the time zone it is currently set in.

2)If set to the default setting, you will see a flashing letter “P” on the screen after pressing and holding the “– /C/F” button. Press and release the “– /C/F” button until the letter shown corresponds to your time zone:

P = Pacific M = Mountain C = Central E = Eastern

Once your zone is displayed, there is nothing more you need to do. After about 3 seconds, the seconds will once again be displayed on your clock.

The antenna icon ( ) will flash on and off during synchronization. If the icon disap- pears, this indicates that the radio signal is not available. If you are unable to obtain a signal after a long period of time, try placing the base unit away from sources of interference such as computers, televisions, cordless phone bases, and other electronic items.

Note: The synchronization process can take 24-72 hours.

Celsius/Fahrenheit:

Press and release the “–” (minus) button. A beep sounds, and the display will change to either Fahrenheit or Celsius.
