Click to set the K3's date and time from your personal computer's time of day clock.
You may wish to first set your personal computer's clock from an authoritative time source such as the National Institute of Standards and Technology (NIST) Internet Time Service. See Configuring Windows 2000 and Windows XP to use NIST Time Servers for guidance. (You may need to install software such as the Adobe Reader to view PDF files.)
There is an Internet Time program built in to Windows 2000 and above. There are also a large number of other Internet Time Service client programs available. See the "Software and Instructions" section of Set Your Computer Clock Via the Internet.
