2. Latitude, longitude, and altitude data can be obtained through the use of a
GPS hand-held receiver (user supplied). Location mapping software is also
available for personal computers, which can be used to obtain latitude and
longitude. When the entered figures are within 1/8 mi of the actual
coordinates, the TimeSource 3500 typically delivers UTC traceable timing
within 1 h of applying power. Warm-up times vary greatly depending on
the window location and antenna placement.
3. Obtain latitude, longitude, and altitude outdoors when using a GPS hand-
held receiver, to ensure an accurate reading. Do not use the GPS hand-
held receiver inside the building near the window or wall where the
antenna will be installed. GPS hand-held receivers do not provide an
accurate location reading when used indoors.
17 If UTC time is desired, skip to Step18. Use the Edit Date command to set the
local date and time.
